Astronomers find record-breaking haul of starless ‘rogue’ planets

A group of researchers found a collection of at least 70 exoplanets without moms and dad stars– the largest single group of rogue worlds ever found– in a patch of area about 420 light-years from Earth, a brand-new study reports.” We did not understand how numerous to expect and are excited to have actually discovered so lots of,” study lead author Núria Miret-Roig, an astronomer at the Laboratoire dAstrophysique de Bordeaux in France and the University of Vienna in Austria, said in a statement.Related: The strangest alien planets (images) This image shows the areas of 115 potential free-floating rogue worlds recently discovered by a group of astronomers in the instructions of the Upper Scorpius and Ophiuchus constellations, highlighted with red circles. Astronomers notice small stellar motions caused by the gravitational tug of an orbiting world, for example, or area small brightness dips caused when a world “transits” its parent stars face.Such methods can not work for rogue worlds, so these worlds are substantially more difficult to discover. And further investigation of these newly found worlds, and others like them, might assist astronomers better comprehend how rogue worlds come to be, study team members said.
