2 days ago · For over a century, scientists have studied Barnard’s Star in hopes of finding planets. First identified by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth. [1] Barnard’s Star is a red dwarf, a type of low-mass star that often hosts compact planetary systems with multiple rocky planets.

Oct 22, 2024 · Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. Every star has its own life cycle, ranging from a few million to trillions of years, and its properties change as it ages. Stars form in large clouds of gas and dust called molecular clouds.
