An artist's illustration of the black hole at the heart of a quasar in the distant universe. The biggest black hole known to exist lives in the nearby galaxy M87. It's 2,000 times bigger than the Milky Way's supermassive black hole.

Black hole...located in the direction of the constellation of Virgo, is so far away that the light from it has taken 11 billion years to reach Earth, so we see it as it appeared in the early Universe. The monster black hole has more than 10 billion times the mass of the Sun and 10,000 times the mass of the super-massive black hole in our own Milky Way, making it one of the most massive ever seen...there may be as many as 400 such giant black holes in the part of the universe... - See more…

A piece of Mars: Wind ha blown the dark, rippled sand between jagged hills, from top to bottom in this frame (663 m or 2175 ft across). Regardless of the terrain, sand finds a way to get through -- just like at the beach, it manages to get everywhere. (HiRISE ESP_037494_1685, NASA/JPL/Univ. of Arizona)
