![]() ![]() Such planets may perhaps have originally formed around a host star before being ejected by the gravitational tug of other, heavier planets in the system. These new events do not show an accompanying longer signal that might be expected from a host star, suggesting that these new events may be free-floating planets. However, the four shortest events are new discoveries that are consistent with planets of similar masses to Earth.Īrtist's impression of a free-floating planet. ![]() Many of these had been previously seen in data obtained simultaneously from the ground. The study team found 27 short-duration candidate microlensing signals that varied over timescales of between an hour and 10 days. During this two-month campaign, Kepler monitored a crowded field of millions of stars near the centre of our Galaxy every 30 minutes in order to find rare gravitational microlensing events. The study, led by Iain McDonald of the University of Manchester, UK, (now based at the Open University, UK) used data obtained in 2016 during the K2 mission phase of NASA's Kepler Space Telescope. Candidate short-duration events from the first space-based survey for planetary microlensing"). The results include four new discoveries that are consistent with planets of similar masses to Earth, published today in Monthly Notices of the Royal Astronomical Society ( "Kepler K2 Campaign 9 – I. ( Nanowerk News) Tantalising evidence has been uncovered for a mysterious population of "free-floating" planets, planets that may be alone in deep space, unbound to any host star.
