What kind of star are at the end of its life?
red giant
A star like our Sun will, at the end of its life, transform into a red giant. Stars are sustained by the nuclear fusion that occurs in their core, which creates energy. The nuclear fusion processes constantly try to rip the star apart. Only the gravity of the star prevents this from happening.
Which star is probably very close to the end of its life?
Betelgeuse is one of the most famous stars in the sky because it’s due to explode someday. Betelgeuse’s enormous energy requires that the fuel be expended quickly (relatively, that is), and in fact Betelgeuse is now near the end of its lifetime.
What is the life of a star?
The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.
What happens to a star at the end of its life?
Once there is no more fuel left to burn, the star will collapse and explode into a supernova — “at which time its brightness will rival that of the rest of our galaxy put together,” noted astrophysicists Paul Butterworth and Mike Arida for NASA’s Imagine the Universe!
What is the life cycle of a massive star?
Beginning of a Massive Star. They typically have a quick main sequence phase, a short red supergiant phase, and a spectacular death via a supernova explosion. Massive stars are born, just like average stars, out of clouds of dust called nebulae. When a nebula collects enough mass, it begins to collapse under its own gravity.
When was the last performance of Big Star?
In June 2011, Ardent Records released the EP Live Tribute to Alex Chilton, and Stephens confirmed on the Ardent blog that the tribute performance in May 2010 was the last performance for Big Star as a band.
What happens to a star when it becomes a supergiant?
When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova.
