We’re very happy to announce a new partnership between NASA and our Zooniverse teams at the Adler Planetarium and the University of Minnesota. This new partnership advances and deepens our existing relationship and efforts with NASA. Our team will work together with NASA to create new opportunities for the Zooniverse volunteer community to engage and participate in projects that span the wide range of NASA’s science divisions: astrophysics, heliophysics, planetary science, and earth science.
This new NASA grant will enable new projects as well as provide support for our developers to maintain our research-enabling platform. This support is very welcome, and will help us share our platform with a growing number of scientists who want to unlock data from NASA’s missions, centers, and projects. We’re really looking forward to building and launching these new projects, but don’t worry — nothing else will change. The platform will still be a welcome home to a wide range of research and projects.
It’s been more than a decade now since the Zooniverse launched, and it’s exciting to have reached the point where the Zooniverse platform, research teams, and AMAZING community of volunteers are consistently recognized as valuable contributors and collaborators in research. The Zooniverse team is excited for this partnership and for the future ahead — here’s to lots more adventures to come!
In the beginning of April 2020, we were notified that subjects from one Zooniverse project were appearing in the subject set of a separate project where they did not belong. In our investigation of the issue, our team determined that this behavior was being caused by a Caesar configuration mistake that used an incorrect Subject Set ID. Project owners using Caesar were able to create Subject Rule Effects that added subjects to collections or subject sets, even without proper subject set editing permissions. We have rectified the issue surrounding Subject Rule Effects and eliminated this vulnerability, and would like to share the details for anyone who is interested.
The issue was raised by project lead James Perry (@JamesPerry), who reported that subjects that didn’t belong to his project were appearing in his subject sets. Due to a mistyped subject set ID in a Caesar `add_to_subject_set` effect for an unrelated project, that Subject Rule Effect was sending subjects from that project to one of James’s subject sets instead of the correct target.
Our immediate course of action was to fix the project impacted by the vulnerability, and push out a temporary code fix to prevent the vulnerability from being exploited.
To fix the affected project, we updated the incorrect subject set id for the project that was incorrectly sending subjects to the wrong project and removed the unwanted subjects from the set.
On April 3rd we deployed a temporary code fix to disable Subject Rule Effect creation and modification for all but admin users (see PR #1109). This change was communicated to affected teams that were most impacted by the change, and teams that reached out after seeing our notification banner or encountering a Caesar interface error.
On May 15th we pushed out a permanent fix that checked the user has permissions to send data to the target subject set or collection. Specifically, the updated validation code checks that the user has update permissions on the project the subject set or collection is linked to. (see PRs #1115, #1129 and #1131).
For anyone running their own hosted copy of Caesar, we recommend pulling these changes as soon as you’re able.
The following is an update from the SuperWASP Vairable Stars research team. Enjoy!
Welcome to the Spring 2020 update! In this blog, we will be sharing some updates and discoveries from the SuperWASP Variable Stars project.
What are we aiming to do?
We are trying to discover the weirdest variable stars!
Stars are the building blocks of the Universe, and finding out more about them is a cornerstone of astrophysics. Variable stars (stars which change in brightness) are incredibly important to learning more about the Universe, because their periodic changes allow us to probe the underlying physics of the stars themselves.
We have asked citizen scientists to classify variable stars based on their photometric light curves (the amount of light over time), which helps us to determine what type of variable star we’re observing. Classifying these stars serves two purposes: firstly to create large catalogues of stars of a similar type which allows us to determine characteristics of the population; and secondly, to identify rare objects displaying unusual behaviour, which can offer unique insights into stellar structure and evolution.
We have 1.6 million variable stars detected by the SuperWASP telescope to classify, and we need your help! By getting involved, we can build up a better idea of what types of stars are in the night sky.
What have we discovered so far?
We’ve done some initial analysis on the first 300,000 classifications to get a breakdown of how many of each type of star is in our dataset.
So far it looks like there’s a lot of junk light curves in the dataset, which we expected. The programme written to detect periods in variable stars often picks up exactly a day or a lunar month, which it mistakes for a real period. Importantly though, you’ve classified a huge number of real and exciting light curves!
We’re especially excited to do some digging into what the “unknown” light curves are… are there new discoveries hidden in there? Once we’ve completed the next batch of classifications, we’ll do some more to see whether the breakdown of types of stars changes.
An exciting discovery…
In late 2018, while building this Zooniverse project, we came across an unusual star. This Northern hemisphere object, TYC-3251-903-1, is a relatively bright object (V=11.3) which has previously not been identified as a binary system. Although the light curve is characteristic of an eclipsing contact binary star, the period is ~42 days, notably longer than the characteristic contact binary period of less than 1 day.
Spurred on by this discovery, we identified a further 16 candidate near-contact red giant eclipsing binaries through searches of archival data. We were excited to find that citizen scientists had also discovered 10 more candidates through this project!
Of the 10 candidate binaries discovered by citizen scientists, we were happy to be able to take spectroscopic observations for 8 whilst in South Africa, and we have confirmed that at least 2 are, in fact, binaries! Thank you citizen scientists!
Why is this discovery important?
The majority of contact or near-contact binaries consist of small (K/M dwarf) stars in close orbits with periods of less than 1 day. But for stars in a binary in a contact binary to have such long periods requires both the stars to be giant. This is a previously unknown configuration…
Interestingly, a newly identified type of stellar explosion, known as a red nova, is thought to be caused by the merger of a giant binary system, just like the ones we’ve discovered.
Red novae are characterised by a red colour, a slow expansion rate, and a lower luminosity than supernovae. Very little is known about red novae, and only one has been observed pre-nova, V1309 Sco, and that was only discovered through archival data. A famous example of a possible red nova is the 2002 outburst in V838 Mon. Astronomers believe that this was likely to have been a red nova caused by a binary star merger, forming the largest known star for a short period of time after the explosion.
So, by studying these near-contact red giant eclipsing binaries, we have an unrivalled opportunity to identify and understand binary star mergers before the merger event itself, and advance our understanding of red novae.
What changes have we made?
Since the SuperWASP Variable Stars Zooniverse project started, we’ve made a few changes to make the project more enjoyable. We’ve reduced the number of classifications needed to retire a target, and we’ve also reduced the number of classifications of “junk” light curves needed to retire it. This means you should see more interesting, real, light curves.
We’ve also started a Twitter account, where we’ll be sharing updates about the project, the weird and wacky light curves you find, and getting involved in citizen science and astronomy communities. You can follow us here: www.twitter.com/SuperWASP_stars
We still have thousands of stars to classify, so we need your help!
Once we have more classifications, we will be beginning to turn the results into a publicly available, searchable website, a bit like the ASAS-SN Catalogue of Variable Stars (https://asas-sn.osu.edu/variables). Work on this is likely to begin towards the end of 2020, but we’ll keep you updated.
We’re also working on a paper on the near-contact red giant binary stars, which will include some of the discoveries by citizen scientists. Expect that towards the end of 2020, too.
Otherwise, watch this space for more discoveries and updates!
We would like to thank the thousands of citizen scientists who have put time into this Zooniverse project. If you ever have any questions or suggestions, please get in touch.
Over the past week a number of students and organizations have reached out to us to see if Zooniverse participation can fulfill volunteering/service hour requirements for graduation, scholarships, etc.
The short answer is — Yes! Many organizations welcome and encourage Zooniverse participation as a way to fulfill service hour requirements.
We recommend that organizations place at the forefront what students/participants get out of these experiences beyond contributing time and classifications. Rather than creating busy work, we favor a model where participants take time to reflect on how their efforts (and the community’s collective efforts) are contributing to our understanding of our world and the broader universe.
Here is one approach for constructing a productive and rewarding volunteer experience for your organization:
Step 1: Share this opportunity with your Organization
Email your organization to see if participation in Zooniverse can be used to fulfill volunteering or other participation requirements. Share this blog post with them so they understand what you would be doing and how you’ll ‘document’ your participation (see Step 8 below).
Step 2: Register at Zooniverse.org
Create a Zooniverse account by clicking ‘Register’ in the upper-right of the Zooniverse.org homepage (only a name and email are required).
Registering is not required to participate in Zooniverse. But it is useful in this case in order to provide a record of participation.
Step 3: Zooniverse background info
Watch this brief animation and video for background/context about the Zooniverse, the world’s largest platform for people-powered research, with 100 active projects and 2 million people around the world participating. Every Zooniverse project is led by a different research team, spanning a wide range of subjects that include: identifying planets around distant stars (PlanetHunters.org), studying the impact of climate change on animals (SnapshotSafari.org) and plants (FloatingForests.org), tracking resistance to antibiotics (Bash the Bug), transcribing handwritten documents (antislaverymanuscripts.org), and more. The collective efforts of Zooniverse projects have resulted in over 200 research publications to date.
Step 4: Choose your project(s)
Choose from the full list of ~100 active Zooniverse projects (see zooniverse.org/projects) or choose from the curated lists of projects below that tend to work well with different age groups, as selected by the Zooniverse team:
Consider these Reflection Questions, or other similar questions. The questions explore the ‘why’ behind this experience. Why do the researchers need your help? How might the results help science? Are you interested in participating in other projects of this type, and why or why not?
For Organizations: Consider sending these via a Google Form or other survey tool for participants to submit responses to these questions. Note: before using the example form above, make a copy of the Google form and send the survey from your own account to make sure you can access the responses.
Each project has a ‘Talk’ discussion forum associated with it (e.g., https://www.zooniverse.org/projects/mrniaboc/bash-the-bug/talk). This is where the researchers and participants from around the world chat with each other — asking questions about the science, weird things people see while classifying, new discoveries, & more. First, explore the discussion threads and check out some of the questions other people have asked. If you’re feeling comfortable, ask the researchers a question about the science, being a scientist, etc. You might start with a question you asked as part of the ‘Reflection Questions’ activity above. The researchers are keen to hear your questions and engage with you. Check back later to see the response, or watch for Talk email notifications, if you’ve enabled them.
Step 8: Document your participation to fulfill your requirements
Once signed in at Zooniverse.org, you’ll see your display name and your total classification count. (If you hover over the doughnut-ribbon in the center top of the page, you’ll see the classification counts for each specific project you’ve participated in.)
Please note that there is no built-in time-tracker within Zooniverse. Many organizations encourage participants to use the number of classifications they’ve contributed as a proxy for time spent on the site. On average, a person contributes 20-75 classifications/hour on most projects (this ranges widely depending on the difficulty of the tasks, the number of tasks for a given classification, etc.).
For example, if someone has done 100 classifications, you can estimate that they’ve spent ~2 hours classifying on Zooniverse; e.g., 2 hours x 50 classifications / hour = 100 classifications. The Organization should add ~45 minutes to this time estimate for the time it takes to carry out the additional ‘meta’ elements of the experience outlined above.
Please note – because we are a small organization and 1000s of students each week are participating in Zooniverse as volunteers, we are not able to sign individual’s ‘certificates of completion’ or other records of that type for volunteer hours. Instead, organizations encourage their participants to take a screenshot of their signed-in Zooniverse.org page showing their personal stats. This screenshot serves as a proxy for documentation of your effort.
For Organizations: Consider using a Google Form or other survey instrument for participants to submit their classification count and a screenshot of their Zooniverse.org page. Note: make a copy of the Google form and send it from your account so you can access the responses.
If you need to reference a 501(c)(3):
While Chicago’s Adler Planetarium, one of the hosts of the Zooniverse web development team, is a 501(c)(3), the Zooniverse is not. Organizations that need to link explicitly to a 501(c)(3) for their volunteering efforts use the Adler Planetarium as the reference. Documentation of the Adler Planetarium’s 501(c)(3) status is provided here.
We recognize it would be helpful to have an easier way to share participation information with organizations for these purposes (though this will need to be done in a very thoughtful way). Please note that because we are a grant-funded web development team, enhancements of this type take time to design, build and implement. If you or your organization have suggestions for how best to share this information, or are interested in helping to support this effort via collaborative grant-writing or otherwise, please let us know.
As always, please don’t hesitate to reach out to firstname.lastname@example.org if you have any questions or suggestions.
These are strange times we live in. With many people ill or worried, and communities all over the world in lockdown or cutting out social contact in order to try and control the spread of the novel coronavirus, it’s hard to work out what the future holds.
The Zooniverse team – including our teams in Oxford and in Chicago – are all working from home, and we’re struggling to master how to communicate and work in this odd situation. So far we’ve encountered all sorts of weird glitches while trying to keep in touch.
But we are still here! As we know lots of you are turning to Zooniverse for a distraction while your lives are disrupted, we’ve asked our research teams to pay particular attention to their projects and to be even more present online during this time. We’ll try and bring you more news from them over the next few weeks.
Anyway, if any of you would like to distract yourselves by taking part and contributing to one of our projects, we’ve made it easier to find a new project to dive into. The top of our projects page now highlights selected projects – they will change frequently, and might be topical, timely, particularly in need of your help – or just our favourites!
Zooniverse projects succeed because they’re the collective work of many thousands of you who come together to collaborate with our research teams – and a little bit of collective action in the world right now feels pretty good.
Look after yourselves, and see you in the Zooniverse.
As schools, workplaces, public spaces, and institutions across the globe close in response to COVID-19, we are aware that, for many people, online platforms like Zooniverse can function as a way to continue to have an impact and remain engaged with the world.
We cannot thank you enough for participating in Zooniverse and creating a welcoming and supportive space for all.
Below is a list of resources educators have used in classrooms that also work well remotely/online. Key to keep in mind is that Zooniverse projects are a great way to expose learners to new opportunities and ways of engaging in real research. These resources are meant to spark curiosity, learning, and exposure to research and the broader world. We encourage you to especially consider what students can gain from the process of participating. Remember: this is an opportunity for experiential learning, not a platform for creating busy work.
Note – there is no age limit for participating in Zooniverse projects, but children under the age of 16 need parent or guardian approval before creating their own Zooniverse account (see here for more details).
Designed for 11-13 year olds, but the content can easily scale down for younger audiences.
Great way to engage if you love looking at photos of wild animals and want to investigate ecological questions. The interactive map allows you to explore trail camera data and filter and download data to carry out analyses and test hypotheses.
Educators can set up private classrooms, invite students to join, curate data sets, and get access to the guided activities and supporting educational resources.
Individual explorers also welcome – you don’t need to be part of a classroom to participate.
A Zooniverse – NASA collaboration through which students learn about citizen science, explore how astronomers search for planets around distant stars, participate directly in the search for exoplanets through PlanetHunters.org, and then design and draw their own planetary system.
Developed by Chicago’s Adler Planetarium Education Specialist Julie Feldt and Adler Director of Teen Programs Kelly Borden.
Through this lesson students observe, record, and document specimens, become a part of the Zooniverse Notes from Nature project, transcribe specimens, connect art and science, and sketch birds in a science notebook.
Designed for middle school classrooms, but the content can easily scale up for older audiences.
See description above.
Astro101 with Galaxy Zoo
Designed for undergraduate non-major introductory astronomy courses, but the content has been used in many high-school classrooms as well.
Students learn about stars and galaxies through 4 half-hour guided activities and a 15-20 hour research project experience in which they analyze real data (including a curated Galaxy Zoo dataset), test hypotheses, make plots, and summarize their findings.
Developed by Julie Feldt, Thomas Nelson, Cody Dirks, Dave Meyer, Molly Simon, and colleagues.
For both Wildcam and Astro101 Activities
Educators can set up private classrooms, invite students to join, curate data sets, and get access to the guided activities and supporting educational resources.
Individual explorers also welcome – you don’t need to be part of a classroom to participate.
Through the Zooniverse FloatingForests.org project, researchers are striving to understand the impact of climate change on giant kelp forests, an indicator of the health of our oceans. In this lab, students analyze Floating Forest and other ocean data to explore their own research questions.
Developed by Cal State – Monterey Bay faculty Dr. Alison Haupt and colleagues
We’d love to hear about your experiences with Zooniverse. Join the conversation in our ‘Talk’ discussion forum around Education and the Zooniverse. There’s a wonderful community there of formal and informal educators and students who are interested in sharing resources and ideas.
If you need a record of your students’ contributions:
You can keep track of how many classifications you’ve contributed if you register (providing a username and email address) within Zooniverse.org. Once signed in, at Zooniverse.org you’ll see your display name and your total classification count. If you hover over the circle surrounding your avatar, you’ll see the classification counts for each specific project you’ve participated in. Some teachers have their students share a screenshot of this zooniverse.org page as a record of contributions.
Please note that there is no built-in time-tracker within Zooniverse. However, participants can use the number of classifications they’ve contributed as a proxy for time spent on the site. On average, a person contributes 20-75 classifications/hour on most projects. So, for example, if a student has done 100 classifications, you can estimate that they’ve spent ~2 hours classifying on Zooniverse; e.g., 2 hours x 50 classifications / hour = 100 classifications.
Today’s cross-post is from ChelseaTroy.com, blog site of one of our Zooniverse developers. Chelsea writes codes for open source projects like our Zooniverse Citizen Science Mobile App and NASA Landsat Image Processing Pipeline. She also teaches Mobile Software Development at the Master’s Program in Computer Science at the University of Chicago.
Chelsea was selected as a NASA Social appointee to attend the launch of last week’s CRS-20 cargo resupply mission to the International Space Station (this included attending the launch of the SpaceX Falcon 9 rocket and Dragon spacecraft, meeting w/ NASA’s social media team, touring NASA facilities at Kennedy, meeting with experts, and more). Check out all her posts on instagram, twitter, and chelseatroy.com.
This post of Chelsea’s, on why the launch was delayed, resonated in particular with us as a web development team. Across many fields, the lessons and insights around the role of deadlines, the value of redundancy, learning from past experiences/mistakes to make better predictions and mitigate risk, etc. apply.
Zooniverse is ten years old! On 12th December 2009, Zooniverse.org sputtered into life, celebrated with a post on this very blog (https://blog.zooniverse.org/2009/12/12/the-zooniverse-is-go/). Truth be told, there wasn’t a huge amount to show – the only project there was our first, Galaxy Zoo, which had been running for a couple of years by that point. What a contrast to today’s bustling home page, with 229 live projects for you to choose from. Early in 2010 two new projects – Solar Stormwatch and Moon Zoo – were launched, before Old Weather became our first project based here on Earth instead of out in the cosmos.
To celebrate, we’re redoubling our efforts to reach two million volunteers. We’re about 50,000 short, so if every one in twenty of you invites a friend to join in we’ll be there in no time. We have a prize lined up for the lucky two millionth, and anyone who classifies on any project on that auspicious day will go into a draw for some Zooniverse swag.
Birthdays are also time for reflection. To be honest, I was a bit surprised when I realised that we were approaching this milestone birthday. Galaxy Zoo had arrived with a big bang, a sudden explosion of effort, but as the above description suggests Zooniverse grew more slowly, as project after project was added to our nascent platform. Over the years, we rebuilt the codebase (more than once), projects came and went, and the army of Zooniverse volunteers grew in strength and in numbers. Looking back, though, the decision we made to launch Zooniverse set in stone some important principles that still guide us today.
For starters, it meant that we were committed to building a universe of projects which volunteers could move easily between. Projects which were lucky enough to get publicity – featuring on BBC Stargazing Live, for example – thus benefited other projects by bringing new people into the Zooniverse community. We built a shared codebase, so that funding for a particular project could support the development of code that benefited everyone. For most participants, their experience of the Zooniverse is limited to the project they’re participating in, whether it involves penguins, papyri or planets, but these network effects have been hugely important in sustaining such a rich variety of projects for a decade.
We’ve always tried to make it as easy as possible for researchers to build the best projects they can imagine, investing in the project builder tool that now supports all of the projects listed on our homepage. The choice – made early – to present the Zooniverse as a tool that’s free for researchers to use has caused problems; we are almost completely dependent on grant funding, which is a risky way to run a railroad, to say the least. But it has meant that those researchers, often early in their careers, have been able to turn to Zooniverse for help without reservation, and I think we’ve had better results – and more fun – as a consequence.
There have been so many great moments over the last ten years, but just for a bit of fun here are my top 3 favourites:
First hearing the Solar Stormwatch results were good – realising the method doesn’t just work for Galaxy Zoo.
Climbing up a hill in the Antarctic to retrieve Penguin Watch data.
So here’s to ten years of the Zooniverse. At any point in the last decade, I’d have been wrong if I’d tried to predict what the next few years would bring. I’m looking forward to more adventures and surprises in our second decade!
PS I can’t possibly list all of the people who were instrumental in building and guiding the project over the years, but I hope the team will forgive me for mentioning Arfon Smith, my co-founder and the technical genius behind the Zooniverse’s first few years, Lucy Fortson, whose wisdom we’ve relied on from the start, and Lauras Whyte and Trouille who have in turn led the Adler team in Chicago through this mad decade. Special thanks too to the volunteers – all of you – but especially Elisabeth Baeten, Jules Wilkinson, and PMason, whose spirit and generosity is a constant source of wonder and inspiration.
Last week, the European Space Agency released the above Image of the Week from the Hubble Asteroid Hunter project. It shows an asteroid passing in front of the Crab Nebula, M1, an image found in the ESA HST archives by citizen scientist Melina Thevenot, who created a colour image of it.
Hubble Asteroid Hunter was created using our Zooniverse Panoptes platform by a team of researchers from the European Space Agency, and launched on International Asteroid Day (30 June 2019) with the aim of identifying serendipitous observations of asteroids in archival Hubble data. Over the almost three decades of observations, HST provided a vast wealth of images that are available in the archives. Many of these images targeting far away galaxies or clusters contain photobombing asteroids, passing in front of the intended targets (for example asteroids passing in front of Abell 370 cluster in the Hubble Frontier Fields – https://hubblesite.org/contents/media/images/2017/33/4082-Image.html?keyword=Asteroids) . Rather than being a nuisance, astronomers realised that the images can be used to better characterise the asteroids themselves and determine their orbits.
A pipeline was set up in ESA’s discovery portal (ESA Sky – https://sky.esa.int/) that matches the asteroids’ predicted positions in both time and space from the IAU Minor Planet Center database with the European HST archival images. The predicted positions of these objects, nevertheless, have some uncertainties as the ephemerides are not always known to great precision. This is a great opportunity for citizen scientists to inspect Hubble images and mark the positions of the trails. Knowing the exact positions of the trails allows researchers to update the ephemerides of the asteroids, and better characterise their orbits. This is important, especially for Near-Earth Objects, which can be potentially hazardous for the Earth.
So far, over 1900 citizen scientists participated in the project, providing over 300,000 classifications. The project was extended with images from the ecliptic plane to search for potentially unknown asteroids, and with other longer exposure archival images to search for possible past interstellar visitors, such as 2I/Borisov. The volunteers have the chance of exploring beautiful Hubble images of galaxies, clusters and gravitational lenses with these new images!
Here at the Zooniverse, we make scientific discovery accessible to the community. Now, we’re incorporating that philosophy into our software engineering.
Our mobile developer, Chelsea Troy, live streams some of her development work on the Zooniverse Mobile App (available on the Apple App Store for iOS and Google Play for Android). This means that you can watch her as she codes, and you can even submit questions and suggestions while she is working! For an introduction to the App and Chelsea’s code development efforts, check out this YouTube video.
Why did we decide to try out live coding? Chelsea talks a little bit about that decision in this blog post. Among the reasons: live coding videos are a great way to attract and recruit possible open source contributors whose work on the Zooniverse mobile app and other codebases could greatly benefit the Zooniverse.
After each live stream, a recording of the session will remain on YouTube. Chelsea also publishes show notes for each stream that include a link to the video, a link to the pull request created in the video, an outline of what we covered in the video (with timestamps), and a list of the parts of the video that viewers found the most useful.
Sound interesting? Willing to contribute to Zooniverse open source code development? Keep an eye on Chelsea’s Twitter account (@heychelseatroy) and blog for future live stream events. But go ahead and check out the recording of her first live stream and show notes to get you started.
