Kissing the Earth Goodbye in About 7.59 Billion Years

By: 

The earth has approximately seven and a half billion years left to live, according to mathematical models made by researchers at University of Guanajuato in Mexico and the University of Sussex in England.

The earth’s demise is being driven by an aging sun, which is actually becoming larger, brighter, and warmer with age.  In fact, life on earth may end well before the 7.5 billion year estimate, when the earth will be engulfed by the sun.  Researchers speculate that one billion years from now, the temperature of earth will have risen to the point where the oceans boil off, effectively ending life on earth.

Although this news sounds  rather bleak, it’s worth noting that estimates of the earliest, single-celled life forms on earth are in the 3 billion-year-old range.  We definitely have some time to explore other solar systems….
