Spacecraft Snaps 1st Photo of Mercury from Orbit

The first spacecraft ever to circle Mercury has beamed home the first-ever photo taken of the small rocky planet from orbit, showing a stark landscape peppered with craters.

NASA’s Messenger spacecraft snapped the new Mercury photo today (March 29) at 5:20 a.m. EDT (0920 GMT). The photo shows the stark gray landscape of southern Mercury, a view that is dominated by a huge impact crater.

NASA’s Hubble Finds Most Distant Galaxy Candidate Ever Seen in Universe

Astronomers have pushed NASA’s Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe. The object’s light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years.

The tiny, dim object is a compact galaxy of blue stars that existed 480 million years after the big bang. More than 100 such mini-galaxies would be needed to make up our Milky Way. The new research offers surprising evidence that the rate of star birth in the early universe grew dramatically, increasing by about a factor of 10 from 480 million years to 650 million years after the big bang.
