3-D climate modeling could fine-tune the search for faraway signs of alien life

Astronomers have identified thousands of stars that have planets, and that number could mushroom even faster when waves of next-generation telescopes come online. But where are the best places to look for life? A newly released study focuses on the most plentiful category of stars in our Milky Way galaxy — M-dwarf stars, also known as red dwarfs — and delivers good news as well as bad news for astrobiologists. The good news is that 3-D climate modeling of atmospheric chemistry can produce a more...

‘Ultima Thule’ no more: New Horizons’ space snowman is named Arrokoth

The snowman-shaped object that NASA's New Horizons probe flew past nearly a year ago on the solar system's icy fringe now has a Native American name: Arrokoth, a word that means "sky" in the Powhatan/Algonquian language. Arrokoth replaces earlier labels for the Kuiper Belt object, including the numerical designation 2014 MU69 and the nickname Ultima Thule, which turned out to be rather controversial. Members of the New Horizons science team announced today that their proposed name has wo...
