A Solution to the Faint-Sun Paradox Reveals a Narrow Window for Life
...the sun was so faint, how was this possible? The faint young sun paradox, as it’s known, has vexed scientists for decades. But recent work has led many researchers to...
Tiny Galaxies Reveal Secrets of Supermassive Black Holes
...astronomers started finding the beasts. In recent years, powerful telescopes and innovative observational strategies have allowed researchers to more closely scrutinize dwarf galaxies. When they do, black holes pop up....
Why Do We Die Without Sleep?
