Adler Zooniverse Summer Intern Experience: Tasnova & Colored Conventions

Leave a comment

By Tasnova, Guest Writer and Adler Zooniverse Summer ’22 Teen Intern

This summer, I worked as an intern for the Adler Planetarium in Chicago, alongside Lola Fash and Dylan. As a group, we carried out Zooniverse projects and interviews with the researchers leading them. In this blog post, I will share about my experience with the main project that I took part in: Transcribe Colored Conventions. 

In July 2022 I interviewed Dr. Jim Casey and Justin Smith, two of the research leads for the Colored Conventions project with Zooniverse. Dr. Casey is an assistant research professor of African American Studies at Penn State University, managing director of the Center for Black Digital Research, and co-founder for the Colored Conventions project. Justin Smith is a Ph.D. candidate in English and African American studies at Penn State and a member of the Douglass Day team.

Before I dig into what the Colored Conventions were, I’d like to share my own experience while working on these projects. I chose to focus on Transcribe Colored Convention because I am a huge history lover. I want to learn everything; learning feeds my curiosity. I was really excited to learn about the Colored Conventions since they are often neglected in textbooks; my school never taught me about the Colored Conventions. It was my first time learning anything about the Colored Conventions. I was so excited to get to interview the amazing people leading the Zooniverse project to transcribe documents related to the Colored Conventions.

The Colored Conventions were events that took place during the nineteenth century and spread across 34 states.  In these Conventions, the participants talked about how they could get access to voting rights, education, labor, and business.

However, despite how important they were, no one really talks about the Colored Conventions today. It is incredibly sad for me to see this important part of our history being neglected.

Another interesting aspect about the Colored Conventions that I learned about through interviewing the team is that the documents related to the Conventions were very male dominated. What this means is that while men’s efforts were well documented in the Conventions’ archive, women’s efforts were not. For example, of the names initially identified and highlighted in the documents, 98% belong to men.

An early researcher who recognized women’s contributions to the Colored Conventions is Dr. Psyche William Foresham, a University of Maryland professor who wrote the essay “What Did They Eat? Where Did They Stay?” In the essay she talked about how women organized restaurants and boarding houses for the people who traveled from other states to join the Convention meeting. They also financially supported them. The essay was eye opening for other researchers, and prompted them to read the Conventions’ documents more carefully to find references to women that might have been overlooked. As a result of these efforts, they found more references to women in the Convention documents.

Zooniverse volunteers also helped transcribe the Colored Convention documents, further unlocking the data for the researchers. The researchers were thrilled to see so many people actually participating in transcribing the documents and caring deeply about the project. The volunteers transcription efforts also uncovered additional evidence of references to women’s efforts in the Colored Convention documents. In my own journey learning about this project, I was happily surprised to see that so many people participated in transcribing the documents and cared about this piece of history that was neglected for so long.

Here are some clips from the full recording of my interview with Dr. Jim Casey and Justin Smith.


A few final thoughts: When I was interviewing the researchers, I loved seeing how passionate they were. It feels rare to talk with people who are passionate about their work. If I see someone who is really passionate about their work and the effort they put in, it’s incredibly motivating. I hope to feel the same in my career.

During my interview, I was nervous in the beginning because this was my first time interviewing a researcher, or anyone. My hands and feet were cold. I tried to calm myself down so I wouldn’t stutter. I think I did a good job interviewing them. My mentor, Sean (who is the Zooniverse designer at Adler), helped me a lot in preparing for the interview. He helped me see that the pressure is not on me as an interviewer; instead, the pressure is on the interviewees because they need to answer the questions. I think that really helped me to calm down because I kept saying to myself that “the pressure is on them, not me.” And my interviewees were such nice people too! I was proud of myself for how I carried out the interview.

Last, but not least, thank you to my teammates Dylan and Lola Fash for helping me out with my summary, video editing, and my blog.

Adler Zooniverse Summer Intern Experience: Dylan & Active Asteroids

Leave a comment

By Dylan, Guest Writer and Adler Zooniverse Summer ’22 Teen Intern

Every once in a while, you get an opportunity that’s so cool, you sort of can’t believe that it’s happening. When I was told that I would have the chance to interview Dr. Colin Orion Chandler, a (then) grad student at Northern Arizona University, who is responsible for creating and leading the Active Asteroids project on Zooniverse, I was beyond thrilled. Every year, the Adler Planetarium in Chicago hires several interns to fill a variety of placements around the museum. As Zooniverse interns, Lola Fash, Tasnova, and I got to interview several researchers on three different projects: Transcribe Colored Conventions, NASA GLOBE Cloud Gaze, and my focus, Active Asteroids. 

What are active asteroids, and why should we care?

Active asteroids are bodies that follow a typical orbit for an asteroid, but, when observed, they are seen to have comae, which are clouds around the object, and tails, which form when water, dry ice, or dust streak out behind the object. These bizarre objects are extremely rare, so we don’t know much about them, but their tails and comae lead researchers to believe that they might have water on them. According to Dr. Chandler, “Water gives us fuel power. Things that we need to drink, to live, gives us things to breathe. It lets us grow food. I mean, it does a huge number of things. But you have to actually know where you might find it and how hard it is to get out of there.”

The hunt for active asteroids

Studying active asteroids could yield remarkable amounts of scientific information, but they are so faint that scientists have trouble finding them. However, the Dark Energy Camera in Chile is sensitive enough to photograph these asteroids, and it sometimes catches an asteroid in part of an image when it was photographing a different object altogether. 

To get data from these archived images, Dr. Chandler and his team break the images into chips, cut out the asteroid, and then focus and enhance the image so that, if there is a tail, we will be able to see it. Will Burris, one of Dr. Chandler’s students, has helped streamline this process. All of these steps have been automated so that computers can process the nearly 30 million images that could contain active objects, and narrow it down to about 10 million where the objects are most likely to appear.

The next step in the process is to identify whether or not there is a tail or coma around the object in the image, and that’s where volunteers come in. Computers are unable to identify active asteroids with a reasonable degree of accuracy, so the task falls to human minds. But, because of the sheer volume of images, Dr. Chandler and his team are unable to process them on their own. Instead, they harness the power of the crowd to classify these images for them, so they can process the data in a reasonable amount of time. When we spoke, Dr. Chandler explained why he opted to go this route, and why he chose to use Zooniverse specifically, stating that, without Zooniverse “It [Active Asteroids] wouldn’t have been as successful, not even by a fraction.”

Once Zooniverse volunteers have fully sorted the data, Dr. Chandler and his team examine the results and single out promising candidates that should be followed up on later with different telescopes. William Oldroyd, in particular, helps with this process. One improvement he’s looking to make is discarding feedback from overly optimistic citizens. Some citizens flag far more asteroids as active than what truly exists, which can throw off the data collected by the Active Asteroids team. The observation and analysis team hopes that they will be able to separate these overly optimistic classifications from the rest, so that they can improve the accuracy of the data that comes in. 

With a complete dataset, Dr. Chandler as well as his project co-founder, Jay Kueny, and their chief science advisor, Chad Trujillo, examine the results. If an object was flagged as active, they follow up in one of two ways; direct observation and archival research.

Studying active asteroids

Pointing a telescope directly at a candidate active asteroid to look for more signs of activity seems like the most obvious way to confirm whether or not it is active. However, this is often difficult for several reasons. 

For one, many candidates are so faint that it can be difficult for even the most advanced telescopes, such as the James Webb Space Telescope, to pick them up. 

For another, they can only be observed at certain times in their orbits, and those intervals are usually years apart. Even if an asteroid is visible, it might not be active at that time, since there are many different reasons that an asteroid becomes active, and they each result in different patterns in activity. In an impact event, activity is temporary and only associated with the collision. Likewise, in the event of a rotational breakup, which occurs when an asteroid spins too quickly and falls apart as a result, an asteroid will only have activity corresponding with breakup events.

The image is one that volunteers classified on Active Asteroids. This object has already been confirmed as active. However, if one were to look at it with a telescope right now, it might not currently have a tail, or it might not be visible at all. (Image Credit: Zooniverse)

The asteroids that are most likely to show repeated activity are asteroids that are active due to sublimation, a process in which, as the asteroid gets closer to the Sun, the frozen carbon dioxide and water on its surface turn into gas and form a coma and tail behind it. Although this is a recurring event, a formerly active asteroid will not always be sublimating, so even if it can be observed, activity might not be detected. 

For all of these reasons, when an object is identified as a promising candidate for activity, researchers prefer to follow up by looking through archived images that contain that object. When we talked, Dr. Chandler referred to “archival investigations” as “instant gratification” since he did not have to deal with the limitations of direct observation, and he could immediately confirm activity and further investigate the object by using images that were already taken. 

Dr. Chandler and his team have already used the results from Active Asteroids to find and study several promising objects, and they are in the process of publishing their findings.

Reflections on my experience

All in all, working as a Zooniverse intern and learning about Active Asteroids has been an amazing experience. Going into the interview, I was worried that Dr. Chandler would be unapproachable and difficult to talk to. However, he seemed more than happy to discuss his work with me, and we actually talked well beyond the time when I’d originally expected the interview to stop. We were able to talk not just about Active Asteroids, but also what it’s like to be an LGBTQ+ person pursuing a career in science. As a young trans person, I often feel like I lack a connection with adults in my community, so getting to talk to someone with an identity similar to mine who was successfully pursuing a career in the field I aspire to join was an incredibly powerful experience. I wish I had a larger word count and some more time since I feel like I could probably write a whole book on interning at the Adler Planetarium and studying the Active Asteroids project on Zooniverse.

When I originally heard about active asteroids, I was mildly intrigued, but not all that excited about writing about them. Although I love all things space related, six months ago I would have said that asteroids are just about the most boring thing in space. However, after having done this project, I’ve become enthralled by active asteroids, and small planetary bodies in general. The idea of all the smaller rocks, tumbling through strange orbits in all kinds of places around the Sun, some with water or other invaluable resources that we may never even find, has found a special place in my heart. I hope this blog post has given you a piece of that.

Adler Zooniverse Summer Intern Experience: Lola Fash & NASA GLOBE Cloud Gaze

Leave a comment

By Lola Fash, Guest Writer and Adler Zooniverse Summer ’22 Teen Intern

This summer I had the opportunity to be a Zooniverse intern at the Adler Planetarium in Chicago, with two other interns, Tasnova and Dylan.  As a group, we carried out a series of interviews with researchers leading Zooniverse projects. My focus project was the NASA GLOBE Cloud Gaze on Zooniverse. I led the interview with  NASA scientist Marilé Colón Robles, the principal investigator for the project, and Tina Rogerson, the co-investigator and data analyst for the project.

NASA GLOBE Cloud Gaze is a collaboration between the Global Learning and Observations to Benefit the Environment (GLOBE) Program, NASA’s largest citizen science program, and Zooniverse. When NASA began to study clouds to understand how they affect our climate, they launched about 20 satellites to collect data on Earth’s clouds.  Unfortunately, these satellites are limited to only collecting data from above the clouds, which only paints half of the picture for scientists. They needed data from the ground to complete the picture. In 2018, they launched the first ever cloud challenge on GLOBE Clouds, which asked people all over the world to submit observations of clouds and photographs of their sky through the GLOBE Observer app. People responded faster than expected, submitting over 50,000 observations across 99 different countries during the month-long challenge. Because of the high volume,  it would take months for researchers alone to go through each submission. So instead, they sought help, thus birthing the Zooniverse CLOUD GAZE project, where people help them classify these photos.  Zooniverse participants classify the photos by cloud cover (what percent of the sky is covered by clouds), what type of cloud is in the image, and if they see any other conditions like haze, fog, or dust.

Why are clouds so important? 

We see the immediate effects of these clouds in our atmosphere. For example, when you go out on a sunny day and the sun gets blocked by low altitude clouds, you feel cooler right away. But rather than looking at short-term effects, the CLOUD GAZE project is working to understand the long-term role clouds play on our climate. 

Clouds play a significant role in maintaining Earth’s climate. They control Earth’s energy budget, the balance between the energy the Earth receives from the Sun and the energy the Earth loses back into outer space, which determines Earth’s temperature. The effects clouds have varies by type, size, and altitude.

Cirrus, cirrostratus, and cirrocumulus clouds are high altitude clouds that allow incoming radiation to be absorbed by Earth, then trap it there, acting like an insulator and increasing Earth’s temperature. Low altitude clouds, such as stratus and cumulonimbus, keep our planet from absorbing incoming radiation, and allow it to radiate energy back into space.

The classifications made by Zooniverse participants are needed to determine the amount of solar radiation that is reflected or absorbed by clouds before reaching the surface of Earth and how that correlates to climate over time. 

In my interview, I had the honor to meet with NASA Scientists Marilé Colón Robles and Tina Rogerson, learn more about the NASA GLOBE Cloud Gaze effort, and hear their predictions for the future. 

Clip 1: Introductions

This first clip is of Marilé, Tina, and me introducing ourselves to one another. Note: The other participants you’ll see in the recordings are Sean Miller (Zooniverse designer and awesome mentor for us interns) and Dylan and Tasnova (my fellow interns).

Clip 2: What prompted you to start NASA GLOBE Cloud Gaze on Zooniverse? 

Quote from Tina from this Clip 2: “We have 1.8 million photographs of the sky. We want to know what’s in those photographs.”

Clip 3: What have your GLOBE participants been telling you about what they’re seeing in their local environments about the impacts of climate change?

What are your hopes and goals for this project? 

In the interview, I asked them about their hopes and broader goals for the project. They talked about how in order to really understand climate change, we need to gather the best data possible. The majority of the data we have on clouds are from the 20th century. One of the project goals was to update our databases on clouds in order to conduct proper research on climate change. Tina Rogerson, Cloud Gaze’s data analyst, gathers this information and compiles it into easily accessible files. The files include data from a range of different sources: satellites, Globe observations, and Zooniverse classifications (see https://observer.globe.gov/get-data). They give people a chance to analyze clouds at different points and connect the dots to analyze the whole.  

Scientist Marilé Colón Robles explained that one of the goals of the project is to make a climatology of cloud types based on the data they have collected. This would help us have a record on how the clouds have changed in a given location in relation to the climate of that area. We would have information on the entire world, every single continent, yes, including Antarctica.

Why did I pick this project to focus on? 

I chose this project because I wanted to challenge myself. I have always shied away from topics and conversations about climate change and global warming. I felt I could never fully comprehend it so I should instead avoid it by all means possible. My fellow interns and I had three projects to choose from: Transcribe Color Convention, Active Asteroids, and NASA GLOBE CLOUD GAZE. If it were any other day, I would have chosen one of the first two projects to be my focus but I wanted to change, to try something new. The only way to grow is to step out of your comfort zone and I am so glad I did. 

People make the mistake of believing that climate change can’t be helped and that after our Earth becomes inhabitable we can just pull a Lost In Space and find a different planet to live on. I had the chance to speak with Dr. Michelle B. Larson, CEO of Adler Planetarium, and we talked about how there isn’t another planet for us to go to if we mess this one up. Even if there was, it would take years and a lot of resources to ready the planet for ourselves. Those are resources and years that we could be spending on fixing our home. 

The CLOUD GAZE focused on one of the most important and understudied factors in Earth’s climate – clouds. People all over the world are helping in their own way to help save the planet. Some make sure to always recycle their garbage. Some take public transportation more often, and switch to electronic vehicles to cut down on their carbon footprint. You and I can help by taking pictures of our sky, submitting it in the GLOBE Observer app, and by going to the Zooniverse Cloud GAZE project, classifying as little as 10 images of clouds per day to multiply the data on clouds, which in turn helps further our research and our understanding of climate change.
