Artists Concept of the WASP-77 A b system. A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets–planets around stars other than the Sun. But predicting when these special events occur can be challenging…unless you have help from volunteers.
Luckily, a collaboration of multiple teams of amateur planet-chasers, led by researcher Federico R. Noguer from Arizona State University and researchers from NASA’s Jet Propulsion Laboratory (JPL) and Goddard Space Flight Center (GSFC), has taken up the challenge. This collaboration has published the most precise physical and orbital parameters to date for an important exoplanet called WASP-77 A b. These precise parameters help us predict future transit events and are crucial for planning spacecraft observations and accurate atmospheric modeling.
“As a retired dentist and now citizen scientist for Exoplanet Watch, research opportunities like this give me a way to learn and contribute to this amazingly exciting field of astrophysics,” said Anthony Norris, a citizen scientist working on the NASA-funded Exoplanet Watch project.
The study combined amateur astronomy/citizen science data from the Exoplanet Watch and ExoClock projects, as well as the Exoplanet Transit Database. It also incorporated data from NASA’s Spitzer Space Telescope, the Hubble Space Telescope (HST), the James Webb Space Telescope (JWST), and La Silla Observatory. Exoplanet Watch invites volunteers to participate in groundbreaking exoplanet research, using their own telescopes to observe exoplanets or by analyzing data others have gathered. You may have read another recent article about how the Exoplanet Watch team helped validate a new exoplanet candidate.
WASP-77 A b is a gas giant exoplanet that orbits a Sun-like star. It’s only about 20% larger than Jupiter. But that’s where the similarities to our solar system end. This blazing hot gas ball orbits right next to its star–more than 200 times closer to its star than our Jupiter!
Want a piece of the action? Join the Exoplanet Watch project and help contribute to cutting-edge exoplanet science! Anyone can participate–participation does not require citizenship in any particular country.

Sols 4295-4296: A Martian Moon and Planet Earth
Using an onboard focusing process, the Mars Hand Lens Imager (MAHLI) aboard NASA’s Mars rover Curiosity created this product by merging two to eight images previously taken by the MAHLI, which is located on the turret at the end of the rover’s robotic arm. Curiosity performed the merge on Sept. 4, 2024, at 06:30:48 UTC — sol 4294, or Martian day 4,294 of the Mars Science Laboratory mission. The onboard focus merge is sometimes performed on images acquired the same sol as the merge, and sometimes using pictures obtained earlier. Focus merging is a method to make a composite of images of the same target acquired at different focus positions to bring as many features as possible into focus in a single image. The MAHLI focus merge also serves as a means to reduce the number of images sent back to Earth. Each focus merge produces two images: a color, best-focus product and a black-and-white image that scientists can use to estimate focus position for each element of the best-focus product. So up to eight images can be merged, but the number of images returned to Earth is two. NASA/JPL-Caltech/MSSS Earth planning date: Wednesday, Sept. 4, 2024
Today’s two-sol plan contains the usual science blocks filled with contact science and remote science to observe and assess the geology surrounding us. However, the Mastcam team is hoping to capture a special celestial event above the Martian skyline as one of Mars’ moons, Phobos, will be in conjunction with Earth on the evening of the first sol of this plan. So everyone look up, and smile for the camera!
Coming back to our beautiful workspace, in this plan there is a focus on targeting the different colors and tones we can see in the bedrock with our suite of instruments. In the image above we can see some of these varying tones — including gray areas, lighter-toned areas, and areas of tan-colored bedrock — with an image from the MAHLI instrument, Curiosity’s onboard hand lens.
APXS is targeting “Campfire Lake,” a lighter-toned area, and “Gemini,” a more gray-toned area situated in front of the rover. MAHLI is taking a suite of close-up images of these targets too. ChemCam is then taking two LIBS measurements of “Crazy Lake” and “Foolish Lake,” both of which appear to have lighter tones. Mastcam is documenting this whole area with a workspace mosaic and an 8×2 mosaic of “Picture Puzzle,” named after the rock in the image above that was taken during the previous plan. Mastcam will also be capturing a 6×3 mosaic of an outcrop named “Outguard Spire” that has an interesting gray rim. Looking further afield, ChemCam has planned a long-distance RMI image of the yardang unit and Navcam is taking a suprahorizon movie and dust-devil survey for our continued observations of the atmosphere to round out this plan.

4 Min Read Talented Teams Tackle Toasty Planet
Simulation of a planet transiting its host star by Exoplanet Watch volunteer Guiseppe Conzo. Credits:
Guiseppe Conzo Exoplanets, look out! Two NASA-funded teams of amateur astronomers are tracking you with their backyard telescopes.
These two teams, called UNITE (UNISTELLAR Network Investigating TESS Exoplanets) and Exoplanet Watch, have combined forces to confirm a new planetary discovery—a toasty “warm Jupiter”.
“I pinch myself every day when I recall that I have made a meaningful scientific contribution to astronomy by helping professional astronomers confirm and characterize a new exoplanet,” said Darren Rivett, a volunteer from Australia who contributed to the effort.
Planets around other stars, called exoplanets, sometimes block the light from the stars they orbit. When this happens, it’s called a “transit”. Amateur astronomers can observe exoplanet transits with their own telescopes by watching for the light from a nearby star to dim.
NASA’s Transiting Exoplanet Survey Satellite (TESS) sees these dimming events, too—many thousands of them. But just seeing a star dim once is not enough. You need to catch multiple dimming events (and perform various other checks) to know that you’ve found a new exoplanet.
That’s where volunteers from the UNITE and Exoplanet Watch projects come in.
These two teams of amateur astronomers have collaborated with the SETI Institute to detect the transit of an object called TIC 393818343 b (aka TOI 6883 b)—proving to the world that this object does indeed contain a planet orbiting a star.
First, the UNISTELLAR and SETI Institute team saw a single transit signal detected by the TESS space telescope. They gathered data to predict when the planet would transit again. They then alerted the UNITE and Exoplanet Watch amateurs to help observe the host star for signs of a transiting planet during the predicted time. The observations from the two networks showed two new transit detections, confirming the predictions, and demonstrating that a planet indeed causes the signals.
This newly discovered giant planet falls into the “warm Jupiter” category of exoplanets, meaning it orbits closer to its host star than Jupiter, or even the Earth does. Astronomers have even predicted that it might, under certain circumstances, migrate still further inward toward its star to become a “hot Jupiter.” Hot or not, thanks to some terrific teamwork, we are now one step closer to understanding the population of planets that lies outside our own Solar System. The news is now published in the Astronomical Journal, and all the citizen scientists involved, including a high school student, are co-authors on this scientific publication, “Confirmation and Characterization of the Eccentric, Warm Jupiter TIC 393818343 b with a Network of Citizen Scientists”.
UNITE (UNISTELLAR Network Investigating TESS Exoplanets) uses the global network of observers with UNISTELLAR telescopes to gather data on TESS exoplanet candidates and long-duration exoplanet transits. To get involved, no matter what kind of telescope you have, visit https://science.unistellar.com/exoplanets/unite/ or reach out to citizenscience@unistellaroptics.com.
Participation is open to everyone, regardless of citizenship. “What I find amazing about the NASA citizen science project is that they involve people from all around the world contributing meaningful observation data that leads to incredible discoveries!” Sophie Saibi, a high school student from California who participated. “Researching as a citizen scientist is something I highly recommend to anyone who gazes at the night sky with awe and wonder,” said Rivett.
Congratulations to everyone on the team! The amateur astronomers who coauthored this paper are listed below.
