![]() ![]() ![]() Confirming the existence and nature of free-floating planets will be a major focus for upcoming missions such as the NASA Nancy Grace Roman Space Telescope, and possibly the ESA Euclid mission, both of which will be optimized to look for microlensing signals. 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. JKepler telescope glimpses population of free-floating planets by Royal Astronomical Society Credit: Pixabay/CC0 Public Domain Tantalizing evidence has been uncovered for a mysterious. when the light from newborn stars wrenched the electrons from free-floating atoms of neutral hydrogen. Confirming the existence and nature of free-floating planets will be a major focus for upcoming missions such as the NASA Nancy Grace Roman Space Telescope. Even though Saturns average distance from the Sun is. 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. MAP Glimpses Universes Rambunctious Childhood. Water has a density of 1 g/cm3 so Saturn would float if there was a water body big enough to hold it. 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. 6 July 2021 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. 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. 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. During this two-month campaign, Kepler monitored a crowded field of millions of stars near the center of our Galaxy every 30 minutes in order to find rare gravitational microlensing events. Phys.Org reports: 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. 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.
