NASA astronaut Mike Hopkins shared this picture of the double volcano on the island of Ambrym in the Pacific archipelago of Vanuatu on Dec. 2 via Twitter.

Steam and ash stream from the twin volcanoes on the island of Ambrym in the Pacific archipelago of Vanuatu, as seen in a picture captured from the International Space Station as it passed overhead. "Not every day you get to see an active volcano, let alone two," NASA astronaut Mike Hopkins tweeted on Monday.

Ambrym is literally one of the hotspots for volcano tourists, but it has been known to turn deadly in the past. To find out more about the island and its double-barrelled volcano (Marum and Benbow), check out Phil Plait's volcano roundup on the Bad Astronomy blog. If you're a Twitter fan, be sure to follow the NASA astronauts' Twitter account for tons of wonderful pictures.
