James Webb Space Telescope Brown Dwarf Milky Way NGC 602
NASA’s James Webb Space Telescope has detected the first rich population of brown dwarf candidates located outside our own Milky Way Galaxy in the star cluster NGC 602. The latter is basically a satellite galaxy approximately 200,000 light-years from Earth, and its local environment is a close analogue of what existed in the early Universe, with very low abundances of elements heavier than hydrogen and helium.
