I've always thought stars are too far away to affect us, but recent findings suggest that's not the case.
Scientists have discovered traces of exploded stars buried in the sea floor across the globe. This proves that these explosions, called supernovae, have showered the Earth with radiation in the last few million years. Not only that, the blasts may have affected the Earth's climate and indirectly the evolution of humans.
I don't know about you, but tonight I'll look at the sky and say thanks.
