Researchers using NASA’s James Webb Space Telescope have formally embarked on a new frontier: Identifying and analyzing rocky exoplanets that orbit red dwarf stars. A team led by Kevin Stevenson and Jacob Lustig-Yaeger, both of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, confirmed that LHS 475 b not only exists, it is a small, rocky planet that is almost exactly the same size as Earth. Before Webb, researchers typically targeted planets that are larger than Jupiter, which is 11 times wider than Earth. This will inevitably be the first of many discoveries Webb data will help researchers make as they continue exploring planets elsewhere in our Milky Way galaxy.
