Navy officer and Visual Survey Group team member. And even we can’t catch them all,” said Tom Jacobs, a former U.S. “People doing visual surveys – looking over the data by eye – can spot novel patterns in the light curves and find single objects that are hard for automated searches to detect. The citizen scientists hunted for signals of transiting worlds over all Campaign 19’s light curves, which record how monitored stars brightened or dimmed.

Incha and her team worked with the Visual Survey Group, a collaboration between citizen scientists and professional astronomers, to scan this dataset for exoplanets. In the end, astronomers only had about seven days of high-quality data from Campaign 19. As the spacecraft began to run low on attitude control fuel, it couldn’t maintain its position long enough to collect useful observations.

K2’s final campaign, number 19, lasted only a month.

When Kepler was retired in October 2018, it had aided the discovery of over 2,600 confirmed exoplanets and many more candidates. This renewed mission, called K2, lasted another four years and surveyed over 500,000 stars. The Kepler team devised a fix that allowed it to resume operations, switching its field of view roughly every three months, a period called a campaign. In 2014, the spacecraft experienced mechanical issues that temporarily halted observations. It was the first NASA mission to find an Earth-size world orbiting within its star’s habitable zone, the range of distances where liquid water could exist on a planet’s surface. This long period of observations allowed the satellite to track changes in stellar brightness caused by planets crossing in front of their stars, events called transits.Īfter four years, the telescope had observed over 150,000 stars and identified thousands of potential exoplanets.

The mission’s initial goal was to continuously monitor a patch of sky in the northern constellations Cygnus and Lyra. It showcases just how good Kepler was at planet hunting, even at the end of its life.”Ī paper about the planetary trio led by Incha was published in the issue of the journal Monthly Notices of the Royal Astronomical Society. “But they’re exciting because Kepler observed them during its last few days of operations. ''These are fairly average planets in the grand scheme of Kepler observations,” said Elyse Incha, a senior at the University of Wisconsin-Madison. The trio of exoplanets – worlds beyond our solar system – are all between the size of Earth and Neptune and closely orbit their stars. Walbolt)Ī team of astrophysicists and citizen scientists have identified what may be some of the last planets NASA’s retired Kepler space telescope observed during its nearly decade-long mission.

A research team worked with a group of citizen scientists and professional astronomers and found three planets in the last bit of data. In the end, astronomers only had about seven days of high-quality data. The final observing campaign of NASA's Kepler Space Telescope lasted only a month.
