A NASA astronaut snapped a truly out-of-this-world selfie during a spacewalk over the weekend. Barry "Butch" Wilmore, commander of the International Space Station's current Expedition 42, took a photo of himself during a spacewalk on Saturday (Feb. 21) that captured a gloriously blue, cloud-studded ocean in the background. Fellow spacewalking NASA astronaut Terry Virts also appears in the shot, reflected in Wilmore's visor.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
The asteroid zoomed by Earth at a perfectly safe distance of around 1.8 million miles (2.9 kilometers).
Images show surprise changes to the spacecraft as it interacted with the atmosphere.
