#TheAccident Gemini South Telescope Aids in Discovery of Elusive Cloud-Forming Chemical on Ancient Brown Dwarf 10-billion-year-old brown dwarf nicknamed The Accident unlocks clues to the chemistry of cloud formation on planets like Jupiter
JWST Accidentally Found 21 Brown Dwarfs JWST is the most powerful telescope ever built by humanity, and it's scanning into the very limits of the observable Universe to see the first galaxies coming together. However, as part of several gal
Astronomers have photographed a brown dwarf orbiting HIP 21152, a young sun-like star in the Hyades Cluster. The newly found brown dwarf called HIP 21152 B, is the first confirmed substellar companion of a main sequence star in Hyades disco
What “browndwarf” means
WikipediaBrown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main-sequence stars. Their mass is approximately 13 to 80 times that of Jupiter (MJ)—not big enough to sustain nuclear fusion of hydrogen into helium in their cores, but massive enough to emit some light and heat from deuterium fusion, 2H, an isotope of hydrogen with a neutron as well as a proton, that can undergo fusion at lower temperatures. The most massive ones can fuse
