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

Brown dwarf crucial for NASA’s Earth-imaging plans The second discovery, HIP 71618 B, also orbits a two-solar-mass star but is a brown dwarf, an object that formed like a star and is intermediate in mass between gas giant planets and stars
- Types - NASA Science
Scientists call a star that is fusing hydrogen to helium in its core a main sequence star Main sequence stars make up around 90% of the universe’s stellar population They range in luminosity, color, and size – from a tenth to 200 times the Sun’s mass – and live for millions to billions of years

Stars are forming every moment, gobbling up gas and dust Precisely how do stars stars form? How do they grow and change? The Hubble Space first generation of stars, also known as Population III stars, were made almost hydrogen and helium Later generations of stars, including the
