A star is born. 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. For … See more The universe’s stars range in brightness, size, color, and behavior. Some types change into others very quickly, while others stay relatively unchanged over trillions of years. See more A normal star forms from a clump of dust and gas in a stellar nursery. Over hundreds of thousands of years, the clump gains mass, starts to spin, and heats up. When the clump's core heats up to millions of degrees, nuclear … See more After a red giant has shed all its atmosphere, only the core remains. Scientists call this kind of stellar remnant a white dwarf. A white … See more When a main sequence star less than eight times the Sun’s mass runs out of hydrogen in its core, it starts to collapse because the energy … See more WebApr 2, 2024 · An exoplanet is any planet beyond our solar system. Most orbit other stars, but free-floating exoplanets, called rogue planets, orbit the galactic center and are untethered to any star. Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. bytedance seal
