End of the Earth by the Sun

Earths basic problem is that the Sun will gradually get larger and more luminous as it goes through life, according to widely held theories of stellar evolution. In its first 4.5 billion years, according to the models, the Sun has already grown about 40 percent brighter. Over the coming , life on Earth will become muggier and more uncomfortable and finally impossible. Even if the Earth were to marginally escape being engulfed, said Mario Livio, an astronomer at the Space Telescope Science Institute, it would still be scorched, and life on Earth would be destroyed.
