Scientists Reveal How Much Time the Sun Has Left
Our Sun is a “middle-aged” star, being halfway through its life, say researchers at the Smithsonian and Harvard College Observatories.

Such calculations became possible just recently, thanks to a new understanding of nuclear reactions and fusion, based on being able to compile data from many different observed stars.
