This long-buried glacier ice is at least 770,000 years old

Thanks to climate change, thawing permafrost in the Canadian Arctic has revealed this glacier remnant that could be more than a million years old.

Planets

So many wondrous moons — just a spaceship ride away

Scientists are studying extraterrestrial moons for clues to how planets form, how life began — and whether there’s life out there right now.
