Just 114 miles from the recently-discovered Hiawatha impact crater under the ice of northwest Greenland, lies a possible second impact crater. The 22.7-mile-wide feature would be the second crater found under an ice sheet, and if confirmed, would be the 22nd-largest crater on Earth.

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.
