NASA's Webb Telescope to Search for Young Brown Dwarfs and Rogue Planets
Release date: December 18, 2019
Astronomers will study the smallest, faintest residents of a nearby stellar nursery
A nearby stellar nursery will be the subject of study with NASA's upcoming James Webb Space Telescope. Astronomers will peer into the stellar cluster NGC 1333 to examine its tiniest, faintest residents, including the smallest brown dwarfs, "failed stars" that don't produce their own light. They will also study "rogue planets," which formed around stars before being tossed into interstellar space to wander forever. The researchers hope to set a boundary between objects that form like stars out of gravitationally collapsing clouds of gas and dust, and those that form like planets, which are created when gas and dust clump together in a disk around a young star. They also hope to distinguish among competing ideas about the origins of brown dwarfs.
