| The red dwarf star Mira A, located 350 light-years from Earth, is famous for its wildly varying brightness, which changes by a factor of 1,000 during every 11-month cycle. It is named for a White Dwarf Star, a small and extremely dense star. Subramanyan Chandrasekhar, nicknamed Chandra, of India had proposed that a white dwarf star eventually collapse under its own weight to form a body whose gravity is so strong that it won't even let out light: a black hole. |
