![]() However, the four shortest events are new discoveries that are consistent with planets of similar masses to Earth. 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. The study, led by Dr 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.ĭuring 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 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. Star associations are open star clusters in which stars are no longer gravitationally bound to each other.Tantalising evidence has been uncovered for a mysterious population of ‘free-floating’ planets which may be alone in deep space, unbound to any host star. Towards the end of life, the planet-hunting Kepler Space Telescope looked at the center of the galaxy and observed an abundance of stars every 30 minutes in. To answer this question, Núria Miret Roig and her collaborators targeted the Upper Scorpius young stellar association to search for these elusive planets. Kepler Space Telescope glimpses population of free-floating planets Written by Sci Fi Generation on JTantalising 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. Until now it was hard to investigate which formation mechanism is more likely, as a large homogenous sample of FFPs was missing. The results include four new discoveries that are consistent with planets of similar masses to Earth. Tantalizing 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. FFPs might originate in two ways: they either form on their own, like stars, through the gravitational collapse of small clouds of gas, or they form like planets around stars and then get stripped off from their stellar systems. Kepler telescope glimpses population of free-floating planets. The nature of free-floating planets (FFPs) is still mysterious. The results were published in the journal Nature Astronomy. Núria Miret Roig of the Institute of Astrophysics at the University of Vienna was involved in this exceptional discovery. The large number of planets now detected provides information about the formation process of stars and planets and important information for future research. These celestial bodies do not revolve around a star and are very hard to find due to their very low brightness. 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. ![]() ![]() With observations of one of the closest star-forming regions to the sun a team of international astronomers discovered the largest population of free-floating planets. ![]()
