Over the years, members of the public have regularly made exciting discoveries and meaningful contributions to the scientific process through citizen science projects. These citizen scientists sometimes mine large datasets for cosmic treasures, uncovering unknown objects such as Hanny’s Voorwerp, or other times bring an unusual phenomenon to scientists’ attention, such as the discovery of the new aurora-like spectacle called STEVE. Whatever the project, the advent of citizen science projects has changed the nature of scientific engagement between the public and the scientific community.
Now, unusual brown dwarf stars discovered by citizen scientists will be observed by the James Webb Space Telescope, with the hopes of learning more about these rare objects. Excitingly, one of the citizen scientists has been named as a co-investigator on a winning Webb proposal.
What is that large dark smudge on Jupiter’s side? It may remind you of a certain scene from the sci-fi film “2010: The Year We Make Contact,” where a growing black spot appears in Jupiter’s atmosphere.
But this is a real photo, and the dark spot is just an elongated shadow of Ganymede, Jupiter’s largest moon. Just like when Earth’s Moon crosses between our planet and the Sun creating an eclipse for lucky Earthlings, when Jupiter’s moons cross between the gas giant and the Sun, they create shadows too.
AI is often touted as being particularly good at finding patterns amongst reams of data. But humans also are extremely good at pattern recognition, especially when it comes to visual images. Citizen science efforts around the globe leverage this fact, and recent results released from the Milky Way Project on Zooinverse show how effective it can be. The project’s volunteer team identified 6,176 “yellowballs”, which are a stage that star clusters go through during their early years. That discovery helps scientists better understand the formation of these clusters and how they eventually grow into individualized stars.
Zooniverse brings out the best of the internet – it leverages the skills of average people to perform scientific feats that would be impossible otherwise. One of the tasks that a Zooniverse project called Backyard Worlds: Planet 9 has been working on has now resulted in a paper cataloguing 525 brown dwarfs, including 38 never before documented ones.
Brown dwarfs are smallish objects sitting somewhere between stars and planets, making them notoriously hard to find. But a recent citizen science project aimed at finding the elusive Planet 9 has instead revealed a treasure trove of these oddities, right next door.
We’re in uncharted territory as the world faces the Coronavirus (COVID-19) pandemic. While the medical community is on the front lines of dealing with this, as well as others who provide critical services in our communities, the best thing many of us can do is to stay home (and wash our hands).
If you’re looking for ways to keep occupied, keep your kids in learning-mode while school is canceled, and expand your horizons — all at the same time — luckily there are lots of space and astronomy-related activities you can do at home and online. We’ve compiled a few of our favorites, including this first one, one that just became available yesterday.
Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War.
Earth: a tiny rocky world, almost too close to the Sun, where life rises and falls, punctuated repeatedly by extinctions. Compared to Jupiter, it’s a gum-drop world: Jupiter is 317.8 times the mass of Earth. And Earth is named after a goddess in German paganism, or so we think.
“Out of all the complexity flows beauty…”

Calling all citizen scientists, geography buffs, fans of the International Space Station and those who love that orbital perspective!
CosmoQuest has a brand new project in coordination with NASA and the Astronomical Society of the Pacific (ASP) where you can help identify features in photographs taken by astronauts from the space station.
The project is called Image Detective. I’ve tried it out, and wow, THIS is a lot of fun!
Now, I absolutely love seeing the images taken of Earth from the ISS, and I routinely follow all the astronauts on board on social media so I can see their latest images. And I also love the concept of regular, everyday people doing science. Plus I’m a big fan of CosmoQuest and their ‘quest’ to bring science to the public.
But still, the setup CosmoQuest has is really great and the process is easy. Citizen scientists are asked to help identify geographic features (natural or human-made) and then determine the location on Earth where the photo is centered.
I found that last part to be the most difficult, but I’ve been known to have trouble reading a map … so I’m hoping that I can improve a bit with more practice.
“The astronauts’ photos of Earth are visually stunning, but more than that, they can be used to study our changing Earth,” said our good friend Dr. Pamela Gay, who is the Director of Technology and Citizen Science at ASP. “From erupting volcanoes, to seasonal flooding, these images document the gradual changes that happen to our landscape. The trick is, we need to make these images searchable, and that means taking the time to sort through, analyze, and label (add metadata) the unidentified images within the database of 1.5 million plus photos.”
The team says that Image Detective spreads the significant work necessary to label all of the images out to citizen scientists across the world.
“This is a unique, powerful, and beautiful image data set that has already yielded excellent research science. But the data set needs the many eyes and minds of citizen scientists to reach its full potential as a publicly available, searchable catalog,” said Dr. Jennifer Grier, a Senior Scientist and Senior Education and Communication Specialist at Planetary Science Institute (PSI) and CosmoQuest’s lead support scientist. “With the additions that citizen scientists as detectives can make, professional research scientists will be able to conduct more research into our changing world, and do so much more effectively.”
This week’s guests are Dr Brad Tucker (@btucker22) and Dr Anais Möller (@anais_moller) of ANU Citizen Science Project for Supernovae. Brad is an Astrophysicist/Cosmologist, and currently a Research Fellow at the Research School of Astronomy and Astrophysics, Mt. Stromlo Observatory at the Australian National University. Anais is a cosmologist based in the Australian National University with an expertise in type Ia supernova cosmology. She has worked at low and high redshift supernovae surveys with the goal to study the effect of dark energy in our Universe.

The original plans for the Juno mission to Jupiter didn’t include a color camera. You don’t need color images when the mission’s main goals are to map Jupiter’s magnetic and gravity fields, determine the planet’s internal composition, and explore the magnetosphere.
But a camera was added to the manifest, and the incredible images from the JunoCam have been grabbing the spotlight.
As an instrument where students and the public can choose the targets, JunoCam is a “public outreach” camera, meant to educate and captivate everyday people.
“The whole endeavor of JunoCam was to get the public to participate in a meaningful way,” said Candy Hansen, Juno co-investigator at the Planetary Science Institute in Tucson, Arizona, speaking at a press conference last week to showcase Juno’s science and images.
And participate they have. Hundreds of ‘amateur’ image processing enthusiasts have been processing raw data from the JunoCam, turning them into stunning images, many reminiscent of a swirling Van Gogh ‘starry night’ or a cloudscape by Monet.
“The contributions of the amateurs are essential,” Hansen said. “I cannot overstate how important the contributions are. We don’t have a way to plan our data without the contributions of the amateur astronomers. We don’t have a big image processing team, so we are completely relying on the help of our citizen scientists.”

“What I find the most phenomenal of all is that this takes real work,” Hansen said. “When you download a JunoCam image and process it, it’s not something you do in five minutes. The pictures that we get that people upload back onto our site, they’ve invested hours and hours of their own time, and then generously returned that to us.”
This video shows Juno’s trajectory from Perijove 6, and is based on work by Gerald Eichstädt, compiled and edited by Seán Doran. “This is real imagery projected along orbit trajectory,” Doran explained on Twitter.
JunoCam was built by Malin Space Science Systems, which has cameras on previous missions like the Curiosity Mars Rover, the Mars Global Surveyor and the Mars Color Imager on the Mars Reconnaissance Orbiter. To withstand the harsh radiation environment at Jupiter, the camera required special protection and a reinforced lens.
Whenever new images arrive, many of us feel exactly like editing enthusiast Björn Jónsson:
Even the science team has expressed their amazement at these images.
“Jupiter looks different than what we expected,” said Scott Bolton, Juno’s principal investigator at the Southwest Research Institute. “Jupiter from the poles doesn’t look anything like it does from the equator. And the fact the north and south pole don’t look like each other, makes us wonder if the storms are stable, if they going to stay that way for years and years like the the Great Red Spot. Only time will tell us what is true.”
Juno engineers designed the mission to enable the use of solar panels, which prior to Juno, have never been used on a spacecraft going so far from the Sun. Juno orbits Jupiter in a way that the solar panels are always pointed towards the Sun and the spacecraft never goes behind the planet. Juno’s orbital design not only enabled an historic solar-powered mission, it also established Juno’s unique science orbit.
Juno spacecraft launched from Cape Canaveral on August 5, 2011. After traveling five years and 1.7 billion miles Juno arrived in orbit at Jupiter on July 4, 2016. The mission will last until at least February 2018, making 11 science orbits around Jupiter, instead of the 32 laps originally planned. Last year, engineers detected a problem with check valves in the propulsion system, and NASA decided to forego an engine burn to move Juno into a tighter 14-day orbit around Jupiter. The current 53.4 day orbit will be maintained, but depending on how the spacecraft responds, NASA could extend the mission another three years to give Juno more flybys near Jupiter.
The next science flyby will occur on July 11, when Juno will get some close-up views of the famous Great Red Spot.
