Ice sheet expansion may have started 2,000 years ago, but we canceled that
Barnes Ice Cap sits on the central plateau of Baffin Island, in the Canadian Arctic. It is the last surviving fragment of the Laurentide Ice Sheet, the largest of the Pleistocene ice sheets, which at its peak buried most of Canada under two miles of ice and locked away around 80 meters of sea level.

On this day in space! Oct. 24, 1946: V-2 rocket takes 1st photos of Earth from space
On October 24, 1946, a V-2 rocket captured the first-ever photo of Earth from space. While these grainy, black-and-white images might not look like much today, they were a huge deal at the time, because no one had ever seen Earth from space before. The V-2 rocket launched from the White Sands Missile Range in New Mexico.
A 1,000-mile cloud on Mars may reveal physics never seen in nature
Every morning during the Martian spring and summer, a thin and extremely long cloud emerges, only to disappear again. The wispy formation appears near the volcano Arsia Mons and gradually elongates until it reaches over 1,000 miles—about the distance from New York to Kansas City as the crow flies—before dissipating. This cycle then repeats for several months.
