Help NASA discover exoplanets, worlds past our photo voltaic system, by a newly launched web site known as Planet Patrol. This citizen science platform permits members of the general public to collaborate with skilled astronomers as they kind by a stockpile of star-studded pictures collected by NASA’s Transiting Exoplanet Survey Satellite (TESS).
“Automated methods of processing TESS data sometimes fail to catch imposters that look like exoplanets,” mentioned venture chief Veselin Kostov, a analysis scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the SETI Institute in Mountain View, California. “The human eye is extremely good at spotting such imposters, and we need citizen scientists to help us distinguish between the look-alikes and genuine planets.”
Volunteers will assist decide which TESS snapshots embrace indicators from potential planets and which of them present planet impersonators.
Want to hunt the skies for uncharted worlds from house? Join Planet Patrol! Watch to be taught how one can collaborate with skilled astronomers and analyze pictures from NASA’s Transiting Exoplanet Survey Satellite (TESS) by yourself. You’ll reply questions on every TESS picture and assist scientists determine in the event that they comprise indicators from new worlds or planetary imposters.

TESS makes use of its 4 cameras to take full pictures of 1 patch of sky, known as a sector, each 10 minutes for a month at a time. This lengthy stare permits TESS to see when planets go in entrance of their stars, or transit, and dim their gentle. Over the course of a yr, TESS collects a whole lot of 1000’s of snapshots, every containing 1000’s of doable planets – too many for scientists to look at with out assist.
Computers are superb at analyzing such information units, however they’re not good, Kostov mentioned. Even essentially the most fastidiously crafted algorithms can fail when the sign from a planet is weak. Some of essentially the most attention-grabbing exoplanets, like small worlds with lengthy orbits, will be particularly difficult. Planet Patrol volunteers will assist uncover such worlds and can contribute to scientists’ understanding of how planetary techniques type and evolve all through the universe.
Planets aren’t the one supply of adjustments in starlight, although. Some stars naturally change brightness over time, for instance. In different instances, a star might really be an eclipsing binary, the place two orbiting stars alternately transit or eclipse one another. Or there could also be an eclipsing binary within the background that creates the phantasm of a planet transiting a goal star. Instrumental quirks may also trigger brightness variations. All these false alarms can trick automated planet-hunting processes.
On the brand new web site, contributors will assist Kostov and his workforce sift by TESS pictures of potential planets by answering a set of questions for every – like whether or not it comprises a number of vibrant sources or if it resembles stray gentle somewhat than gentle from a star. These questions assist the researchers slim down the record of doable planets for additional follow-up research.
Citizen scientists can dive even deeper by studying extra concerning the star in every picture and by partaking with the Planet Patrol neighborhood.
A Goddard summer time intern just lately helped uncover the TESS mission’s first planet orbiting two stars by one other citizen science program known as Planet Hunters TESS, run by the University of Oxford.
“We’re all swimming through the same sea of data, just using different strokes,” mentioned Marc Kuchner, the citizen science officer for NASA’s Science Mission Directorate. “Planet Hunters TESS asks volunteers to look at light curves, which are graphs of stars’ brightness over time. Planet Patrol asks them to look at the TESS image directly, although we plan to also include light curves for those images in the future.”
Planet Patrol is a collaboration between NASA, the SETI Institute in Mountain View, California, the Space Telescope Science Institute in Baltimore, and Zooniverse, a collaboration of scientists, software program builders, and educators who collectively develop and handle citizen science tasks on the web. It is funded by the Sellers Exoplanet Environments Collaboration at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center. Additional companions embrace Northrop Grumman, based mostly in Falls Church, Virginia; NASA’s Ames Research Center in California’s Silicon Valley; the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts; MIT’s Lincoln Laboratory; and the Space Telescope Science Institute in Baltimore. More than a dozen universities, analysis institutes, and observatories worldwide are contributors within the mission.
