When a star dies, its core becomes smaller, gets hotter and the star turns into a red giant. Larger stars collapse, due to their own gravity, and become supernova.Continue Reading
Because stars run on hydrogen, the hydrogen fuses and gets turned into helium. This causes them to be bright in the sky and burn hot. Eventually, stars run out of hydrogen and the star begins to die. When this happens, the helium begins turning into carbon. As the star cools, it becomes a white dwarf and then a black dwarf.
Large stars go through a similar process when they begin to die, but because they have so much carbon built up, they fuse to heavier elements. These elements cause the star to become heavier, and its gravity causes it to collapse. In time, the star will form a neutron star or a black hole.Learn more about Astronomy
Multiple private companies offer, for a fee, to "register" names or titles of ownership for stars. These companies are not affiliated with any official bod,y and their services are not recognized by any academic organization. The International Astronomical Union, which maintains star catalogs, disassociates itself entirely from the concept.Full Answer >
Stars have a core temperature of anywhere between 5,000 and 200,000,000 degrees Fahrenheit. Temperature widely varies depending on the color of the star. Red stars are the coolest; blue stars are the hottest; and orange, yellow, and white stars fall in between.Full Answer >
When the temperature of a protostar rises higher than 10,000,000 K, it becomes a true star. At this temperature, hydrogen fusion begins to happen. Fusion heats the star, contracts the core and causes the star to emit light. A protostar must have 0.08 solar masses to become a star.Full Answer >
Although a shooting star looks like a star shooting across the sky, it's actually a meteor, or small rock that hits Earth's atmosphere. Because of the speed at which the meteor, or meteoroid, is traveling it burns and releases a glow.Full Answer >
