U!Scientist and the Galaxy Zoo Touch Table at Adler Planetarium

“Everyone try to grab the same galaxy,” a boy exclaimed while motioning to his classmates. Around the table, six students began dragging an image of a galaxy from the center of a large touch screen onto their own workstation. It’s very likely these students are the first people to set eyes upon this galaxy and decide how it should be classified. This kind of work isn’t reserved for astronomers in observatories or researchers in labs. Any visitor to the Adler Planetarium in Chicago can participate in real scientific research through the new U!Scientist touch table exhibit.

In July, the Zooniverse team finished their year-long development of a multi-person touch table experience and accompanying exhibit to remain on the Adler floor for several years. On the touch table, visitors participate in the Galaxy Zoo project (galaxyzoo.org), which provides valuable data to researchers in the U.S. and abroad by asking volunteers to classify galaxies by shape. In an effort to bring the Zooniverse experience to the Adler floor, the National Science Foundation awarded the Adler-Zooniverse team a grant to design a multi-person touch table experience, allowing guests to participate in the Zooniverse in a more social, collaborative way.

At the table, guests step up to their own color-coded workspace and select galaxies from an explorable image sliver of space in the middle of the table. Next, the guest must decide if the galaxy is smooth in shape, contains unique features, or isn’t a galaxy at all. After submitting a classification, the volunteer is shown a quick tally of how past volunteers have classified the galaxy. Adler visitors of all ages, from school groups to grandparents, are becoming quick Zooniverse volunteers.

U!Scientist includes some firsts for the Zooniverse, including the ability to collaborate directly with one another while classifying. When finding an oddly-shaped galaxy, volunteers can send the image to a neighbor for advice or begin a conversation with their group. Hopefully, these in-person conversations about science will spark curiosity and cause planetarium visitors to become active Zooniverse volunteers online.

Since cutting the red ribbon, guests are finding new ways to interact with the exhibit. Couples take the opportunity to compete with one another in classifying the most galaxies, facilitators explain the research process to campers arriving early to the museum, and children outsmart their parents by explaining the shape of galaxies using examples at each workstation. On average, Adler guests are responsible for over one thousand classifications per day through U!Scientist.

Want to see how the touch table app is doing? Visit uscientist.org to see a running tally of U!Scientist and Galaxy Zoo classifications as well as a world map of current classifications through Galaxy Zoo.

The U!Scientist touch table exhibit is supported by the National Science Foundation under grant #AISL-1713425.

Experiments on the Zooniverse

Occasionally we run studies in collaboration with external  researchers in order to better understand our community and improve our platform. These can involve methods such as A/B splits, where we show a slightly different version of the site to one group of volunteers and measure how it affects their participation, e.g. does it influence how many classifications they make or their likelihood to return to the project for subsequent sessions?

One example of such a study was the messaging experiment we ran on Galaxy Zoo.  We worked with researchers from Ben Gurion University and Microsoft research to test if the specific content and timing of messages presented in the classification interface could help alleviate the issue of volunteers disengaging from the project. You can read more about that experiment and its results in this Galaxy Zoo blog post https://blog.galaxyzoo.org/2018/07/12/galaxy-zoo-messaging-experiment-results/.

As the Zooniverse has different teams based at different institutions in the UK and the USA, the procedures for ethics approval differ depending on who is leading the study. After recent discussions with staff at the University of Oxford ethics board, to check our procedure was up to date, our Oxford-based team will be changing the way in which we gain approval for, and report the completion of these types of studies. All future study designs which feature Oxford staff taking part in the analysis will be submitted to CUREC, something we’ve been doing for the last few years. From now on, once the data gathering stage of the study has been run we will provide all volunteers involved with a debrief message.

The debrief will explain to our volunteers that they have been involved in a study, along with providing information about the exact set-up of the study and what the research goals were. The most significant change is that, before the data analysis is conducted, we will contact all volunteers involved in the study allow a period of time for them to state that they would like to withdraw their consent to the use of their data. We will then remove all data associated with any volunteer who would not like to be involved before the data is analysed and the findings are presented. The debrief will also contain contact details for the researchers in the event of any concerns and complaints. You can see an example of such a debrief in our original post about the Galaxy Zoo messaging experiment here https://blog.galaxyzoo.org/2015/08/10/messaging-test/.

As always, our primary focus is the research being enabled by our volunteer community on our individual projects. We run experiments like these in order to better understand how to create a more efficient and productive platform that benefits both our volunteers and the researchers we support. All clicks that are made by our volunteers are used in the science outcomes from our projects no matter whether they are part of an A/B split experiment or not. We still strive never to waste any volunteer time or effort.

We thank you for all that you do, and for helping us learn how to build a better Zooniverse.

AAAS Symposium in Feb. 2015: Cutting-Edge Research with 1 Million Citizen Scientists

Some colleagues and I successfully proposed for a symposium session on citizen science at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Jose, CA in February 2015. (The AAAS is the world’s largest scientific society and is the publisher of the Science journal.) Our session will be titled “Citizen Science from the Zooniverse: Cutting-Edge Research with 1 Million Scientists.” It refers to the more than one million volunteers participating in a variety of citizen science projects. This milestone was reached in February, and the Guardian and other news outlets reported on it.

AAAS-logo

As we all know, the Zooniverse began with Galaxy Zoo, which recently celebrated its seventh anniversary. Galaxy Zoo has been very successful, and it led to the development of a variety of citizen science projects coordinated by the Zooniverse in diverse fields such as biology, zoology, climate science, medicine, and astronomy. Most of you are familiar with many of them, and the projects include, for example: Snapshot Serengeti, where people classify different animals caught in millions of camera trap images; Cell Slider, where they classify images of cancerous and ordinary cells and contribute to cancer research; Old Weather, where participants transcribe weather data from log books of Arctic exploration and research ships at sea between 1850 and 1950, thus contributing to climate model projections; and Whale FM, where they categorize the recorded sounds made by killer and pilot whales. And of course, in addition to Galaxy Zoo, there are numerous astronomy-related projects, such as Disk Detective, Planet Hunters, the Milky Way Project, and Space Warps.

We’re confirming the speakers for our AAAS session now, and the plan is to have six speakers from the US and UK who will introduce and present results from the Zooniverse, Galaxy Zoo, Snapshot Serengeti, Old Weather, Cell Slider, and Space Warps. I’m sure it will be exciting and we’re all looking forward to it! I’m also looking forward to the meeting of the Citizen Science Association, which will be a “pre-conference” preceding the AAAS meeting.

Taiwan Teachers Workshop

Teacher professional development workshops run in conjunction with science meetings offers educators and scientists a unique opportunity to learn from one another.  On Sunday March 2, 2014 the Taiwan Teachers Workshop was held as part of the Citizen Science in Astronomy Workshop  at the Institute of Astronomy and Astrophysics at Academia Sinica in Taipei.  The Citizen Science in Astronomy Workshop brought together astronomers, data scientists, and web developers together to discuss the challenges of working with large datasets and best practices in utilizing the power of citizen science to work with these datasets.  Recognizing an opportunity to bring Zooniverse project scientists together with area educators,  Meg Schwamb, Stuart Lynn, Lauren Huang and Mei-Yin Chou worked with teachers to introduce concepts of citizen science with special focus on Planet Four and Galaxy Zoo.  Earlier this year these two projects were translated into Traditional Chinese as part of  Zooniverse’s push to translate various projects into as many languages as possible through the efforts of our extensive volunteer community.

To add to this translation effort, a number of existing Zooniverse educator resources were also translated into Traditional Chinese including Planet Four & Galaxy Zoo lesson plans and Galaxy Zoo teacher and student guides.  You can find the workshop presentations and links to the translated educational materials at  http://taiwan.zooteach.org/.

 Funding for the Taiwan Teachers Workshop was generously provided by Taiwan’s Ministry of Science and Technology.

 

 

 

Thoughts From the Classroom: Kat

Kat is sharing her impressions of Galaxy Zoo and Radio Galaxy Zoo as the fifth post in our Thoughts From the Classroom series.  

My name is Kat and I attend a school called GATE Academy.  Let me tell you a story about my experience with Galaxy Zoo.

Two months ago, my teacher discovered Galaxy Zoo.  She thought it would be a good class activity, so she had us read some articles as background information for what we were about to be doing on Galaxy Zoo.  These articles included information about the different characteristics of the different galaxy types and how this galactic information ties into the evolution of our Universe.  It hadn’t occurred to me before that galaxies tie into the Universe as a whole, but it made sense once I read it and I thought it was fascinating.  Then we started actually classifying galaxies as our class assignment.

In retrospect, I should have been amazed and acknowledged how incredible looking at these far-off galaxies was, but I just didn’t see it at the time.  I overlooked it because my mind was set on it being a class assignment and how I just needed to do it to get a good grade.

When I started, all that came up on my screen were pictures of blobs of clumpy blurry things.  I wasn’t very impressed.  Everyone around me, though, started seeing beautiful, wonderful images of incredible galaxies.

This is when I understood what a privilege it was to be participating in this new, cutting edge, amazing research.  On my screen showed actual galaxies from outer space.  It struck me how little we know about the universe around us, because nobody really knows what’s out there.  We have hypotheses, but, honestly, anything could be out there. I became proud of the blobs I classified, because you really needed to look and observe the characteristics, unlike perfect, sharp, clear galaxies (but these were really quite beautiful).  There was more mystery in the blobs for me, so classifying them correctly (or as close as I could get) became my challenge.

I learned a lot about classifying these galaxies along the way. The Zooniverse taught me about how galaxies can be spiral, irregular, or smooth, with bars, clumps, and varying sizes of central bulges.  I learned about how black holes are visible in radio telescopes but not in infrared.  I also learned the different types of black holes, such as compact, extended, and multiple.

After seven weeks of classifying these galaxies, my classmates and I had classified over 9,000 galaxies.  We were all proud of our accomplishment and of all we had learned along the way. I definitely recommend you at least try classifying on Galaxy Zoo, whether its galaxies or black holes or what have you.  Why not?  Don’t you want to say you’ve had the experience?  Would you like to contribute to our knowledge of the universe, or even do your OWN original research about the wonders around us?  If you have any of those interests, or just want to check it out because it sounds cool (and trust me, it is), definitely go to Galaxy Zoo and start classifying.

Thoughts From the Classroom: Riley & Harrison

This fourth post in our Thoughts From the Classroom series comes from Riley and Harrision.  Riley and Harrison are 8th grade students at Gate Academy and are both Galaxy Zoo volunteers.

Riley:

Galaxy Zoo is a great program. It was brought to my attention when we began using Galaxy Zoo in class. It was extremely interesting because I had never seen pictures of our universe like the ones I am able to see on Galaxy Zoo. On one picture, we found an amazing spiral galaxy with such a huge level of clarity, you could even see individual stars. It just blew me away.

Galaxy Zoo is enlightening about the true scale and beauty of our universe. In the background of these immense galaxies you can see dozens of smaller galaxies, which are really just as huge as the one you’re getting a close up of. How cool is that? The structures are so massive but detailed down to the tiniest level, as demonstrated on Earth. I think that everyone should give themselves a chance to appreciate our Universe.

Galaxy Zoo really provided me with food for thought, and I recommend it strongly to anyone with the vaguest curiosity about what’s up there.

Harrison

I’m Harrison, and I used Galaxy Zoo in my middle school class. We instantly loved it because, it’s the perfect combination of learning about the different types of galaxies and having fun while doing it.  Using Galaxy Zoo also gives you a feeling of helping scientific research, by helping progress our scientific understanding of the Universe. The website is user friendly allowing you to classify galaxies, check your personal account, and see other information with a click of a button. The website is interactive and awesome showing you breath-taking pictures that you get to classify. There is so much to do and you can easily be lost for hours. I would recommend Galaxy Zoo to anyone.

More Languages, More Science: Translating Zooniverse Projects

For a long time we’ve tried to translate Zooniverse projects and this has often worked out very well. When we have done it, we have definitely seen the benefits. For example, we know that Polish classifiers on Galaxy Zoo did more classifications per-person than their English-speaking counterparts in 2011. About 8% of all our classifications are completed by people using our websites in a language other than English. We think that number should be higher.

In the last year we’ve launched Galaxy Zoo in Spanish, Traditional and Simplified Mandarin, and Italian. Planet Four is also available in Traditional Mandarin. Plankton Portal is available in Polish and French. Planet Hunters is also available in Polish, and Snapshot Serengeti is in Polish and Finnish. Finally, Whale FM is available in Polish, German and Whale.

This has all been possible because of the hard work of colleagues and translators all around the world. We’re currently working on a place to credit them for their efforts so you know who’s been making this magic happen. Particular thanks should also go to Chris Snyder and Michael Parrish, at Zooniverse’s Chicago HQ, for their efforts in making our sites and infrastructure better at handing multiple languages.

If you take a look at the Zooniverse Community Map we created to celebrate our millionth signup you’ll note the strong English-speaking dominance. Whilst this understandable, it’s still not ideal. We need to light up more of the world on that map. So recently several of our core team have been working to make more and more projects translatable. Currently the list stands at:

  • Galaxy Zoo
  • Disk Detective
  • Radio Galaxy Zoo
  • Plankton Portal
  • Planet Four
  • Milky Way Project
  • Worm Watch Lab

…and more are being added all the time. If you’re interested in helping out, please email me on rob@zooniverse.org and let me know your Zooniverse username and the language, and project(s) you’re interested in translating. We hope to bring you updates soon.

Thoughts From the Classroom: Jack and Brendan

In the second installment of Thoughts From the Classroom, we hear from Jack & Brendan two of Victoria’s 8th grade students from Gate Academy in San, Rafael, California.  We asked them to tell us  about their experience using Galaxy Zoo and Radio Galaxy Zoo in the classroom.

Jack

Hello my name is Jack and I go to Gate Academy in San Rafael, California. My classmates and I have been using Zooniverse websites, mainly Galaxy Zoo, to help us with our studies. Our class has benefited greatly from using Zooniverse websites.

Galaxy Zoo is a great site and has taught me a lot about galaxies. I went from knowing next to nothing about classifying galaxies to being able to identify a spiral or bar at only a single glance. Galaxy Zoo helped our class learn about different kinds of galaxies and how to tell if it is disturbed, or even if it has a lens or arc. If my class had not experienced Galaxy Zoo, we would all know a lot less about galaxies.

If you are a teacher and you want your students to learn about galaxies, Galaxy Zoo is a wonderful site.  I would put it at the top of my suggestion list. I hope people everywhere use this site, and that they all like it as much as I do.

Brandon

My name is Brandon and I’m a middle school student at GATE Academy, San Rafael. I love soccer and programming. I want to tell a little more about my experiences with Galaxy Zoo, and its uses as an educational tool. While using Galaxy Zoo, I had a chance to learn a lot while also contributing to the Zooniverse project. For instance, black holes show up on radio telescopes but not infrared, although sometimes associated galaxies can show up on the infrared near the black hole. I learned this from Radio Galaxy Zoo, the part of Galaxy Zoo that focuses on finding black holes. While I was learning about radio telescopes and black hole jets, I realized that I was also helping add to the reserves of information that scientists can draw on during their work. Overall, I think that Galaxy Zoo can really help students learn and also helps advance science. My time with Galaxy Zoo has shown me what a wonderful universe we live in and taught me a lot in the process.  I think other students should have a chance to have that experience too.

Thoughts from the Classroom: Thinking of using Galaxy Zoo in your middle school classroom? Do it!

Today’s post comes from Victoria Talkington and kicks of a short series called Thoughts from the Classroom. Victoria is a middle school teacher at GATE Academy.  She and her students recently dove head first into the Zooniverse with Galaxy Zoo by completing over 9,000 classifications (many thanks from the science team)!  Victoria’s students also contacted Galaxy Zoo scientists and developers with their questions.  In today’s post Victoria tells about why she chose to bring Galaxy Zoo into her classroom.  In the coming weeks we’ll also share some her students’ impressions of participating in an online citizen science project as part of the Thoughts from the Classroom series.  Here at Zooniverse we thought is was about time we started listening directly to student perspectives on our projects.

I chose Galaxy Zoo for my middle school class because it’s real science.  It’s hands-on, minds on science, with the thrill of possible discovery.   Galaxy Zoo may seem, to the uninitiated, to be an addictive, time-sink fantasy game, with pretty pictures of dust lanes, swirling gases, and spiral galaxies.  In fact, it is the ultimate cosmology reality show.  Galaxy Zoo packages community involvement, cutting edge research, and classification skills, and draws kids in to a place where they are DOING something meaningful and genuine for all the world.

I’m an educator at GATE Academy, a school for academically gifted kids in Northern California.  My BA at Yale was in molecular biophysics and biochemistry, back in the late 1970’s when biotech was in its infancy.  After a stint at Harvard Law School for my JD, followed by a long career as a trial attorney, and then a decade of volunteer service in complex, multi-party administration arenas,  I started my fourth career in education.  With the internet and handheld devices making content oh-so-cheap, I realized that education has fundamentally changed.

Learning about the stars is not enough.  Kids need chances to do something valuable in the world.  The challenge that science faces today in attracting enthusiastic kids is that we’ve travelled so far.  What happens in labs and research is simultaneously too rarified and too granular to grab a young mind.  There’s too much start up time involved, and the details of the periodic table can seem remarkably dull when there’s MindCraft to play after school.

Galaxy Zoo cuts to the chase and ignites in kids an understanding that there is excitement and discovery out there beyond the pixels of fantasy software.  Galaxy Zoo teaches that everything hasn’t been discovered – there are still galaxies to hunt.  Kids can be Captain Kirk traveling on the Starship Enterprise, for real.  They can go where no human has gone before, looking at distant images, trying to understand what they are, and keeping their own captain’s log of their observations — or simply rely on the strong, slick classification tools of Galaxy Zoo.  Galaxy Zoo enables kids to discover how the hard work of real science opens their minds, and makes them curious about their world.

If I were to suggest starting your a class on Galaxy Zoo, I’d have the kids dive right into classifying with only minimal introduction.  And you know, what they are doing will be puzzling and it won’t make too much sense to them at first.  So, they will start asking questions.  List their questions on a board, but don’t answer them.  Maybe they won’t see the point.  You’ll be able to suggest that they look at the Galaxy Zoo “Story” for homework.  They’ll read it — and a couple of kids will “get” what the adventure is.  You can talk together about it at the next class– what do the kids think they are doing?  Guide them into understanding that they are helping to figure out how galaxies form, and that this thing, this task that they are involved in, is how true discovery and scientific work takes place –  image by image, galaxy by galaxy, categorization by categorization.  How many classifications do they think they can achieve over the duration of your term?  Set a goal.  And gently, as your kids become more and more engrossed in Galaxy Zoo classifying, you can start introducing readings on galaxies.  Little current news items from, say Scientific American or Science News.  Somehow, suddenly, what would have been dry content for most of the class, greeted by groans or (worse),  becomes material that most of them are interested in.  They might even start doing Galaxy Zoo classifications at home . . . instead of MineCraft.  Who knows?  A new Captain Kirk might be discovered in your classroom.  Teaching for the stars.

Galaxy Zoo & Galaxy Zoo Navigator Student & Teacher Guides

Today’s post comes from Kate Meredith who created and recently posted the teacher and student Galaxy Zoo guides outlined here. Kate is a former middle school and high school teacher who considers herself a virtual person in the Sloan Digital Sky Survey database.  She has been involved with pilot testing, writing and training teachers to use the database for the past twelve years.  She is very excited about how the Galaxy Zoo Navigator tools can help teachers engage groups of students to use images from the SDSS in ways that are fun and accessible. 

Guides and help documents for getting started with Galaxy Zoo and the Galaxy Zoo Navigator are available now on ZooTeach.  There is something for teachers and students.
