Bioluminescence, the eerie, beautiful phenomena that allows living things to glow, is way more ancient than previously thought, according to a team of researchers that recently studied the ability in octocorals.

On Earth Day, the National Weather Service and the Centers for Disease Control and Prevention teamed up to announce a new heat risk system to better communicate the severity of hot weather. The color-coded system added magenta, a fifth-tier of heat severity, beyond red, to communicate extreme heat “rare and/or…

The Voyager 1 spacecraft returned usable data for the first time in more than five months, giving hope for the 46-year-old mission to finally be able to resume its normal operations.
