The Dawn spacecraft has made history. It has become the first mission to visit a dwarf planet when it successfully slipped into Ceres' orbit on March 6.
It's a spacecraft shadow on a comet! Rosetta caught its own shadow encircled in a wreath of light, on the icy surface of Comet 67P/Churyumov-Gerasimenko.
A black hole 12 billion times more massive than our sun - at the heart of the brightest quasar in the early universe - as the dark ages of the universe were just ending.
The comet was 51 million miles from Earth at the time – a short distance for the Dark Energy Camera, which is sensitive to light 8 billion light-years away.
Lucky observers in western North America saw bright lights streaking in the sky Monday night - the disintegration of a Chinese rocket body. Photo and videos here!
