Jan 30, 2023 · Today, approximately 4.5 billion years later, the Sun is still in the main sequence phase of its lifecycle, fusing hydrogen atoms together into helium to produce energy in the form of radiation including primarily heat and light.
Sep 5, 2021 · The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years.
Aug 12, 2022 · Life on Earth, for the record, only has about a billion years left, unless we do something catastrophically stupid, or something catastrophic happens to us. That's because the Sun is increasing in brightness by about 10 percent every billion years ; which means it is also increasing in temperature.
Dec 22, 2015 · The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons...
