In a billion years, the sun will start to run out of fuel and expand to become a red giant. Earth's oceans and atmosphere will be burned away, and Earth will likely be engulfed by the sun altogether. The sun will then shrink ...
Researchers at Uppsala University have calculated that the sun contains 55% more silver than previously estimated. The results are based on more realistic modeling of the sun's atmosphere and resolve a long-standing problem ...
