Backyard Worlds: Binaries

https://science.nasa.gov/citizen-science/backyard-worlds-binaries/?utm_source=newsletter&utm_medium=email&utm_campaign=nn202624 Most stars in our Milky Way galaxy exist in groups, including pairs or “binaries,” in which two stars orbit each other. Some binaries are stars paired with brown dwarfs, balls of gas more massive than planets without enough mass to sustain nuclear fusion. Finding brown dwarfs in pairs helps scientists deduce their ages and origin stories! Backyard Worlds: Binaries invites you to search images made by NASA’s Wide-field Infrared Survey Explorer (WISE) space telescope to find these vital brown dwarfs in binary systems. Your discoveries will teach us about brown dwarf formation and identify objects that resemble giant planets like Jupiter.
