NASA releases images and video of the comet ISON streaking through the sky towards the sun.
Pluto may never again be considered a proper planet, but at least it won't be lonely. The Hubble Space Telescope has spotted another moon orbiting the dwarf planet — raising Pluto's satellite count to five — as Hubble was checking out the plutoid for a Pluto-bound NASA mission.
Keep your specs on and stock up on water and canned goods, because the Milky Way, that thing we've been blasting with a laser, is going to collide with the Andromeda galaxy. Well, in about 4 billion years, but it's never too late to be prepared.
The Hubble Telescope has captured some amazing pictures in its day, but this one is warped. In a good way.
According to astronomer Zachory Berta, "GJ1214b is like no planet we know of." That's because a "huge fraction" of the planet is made up of water — a concept that's hard to drink in when one considers the fact that GJ1214b is a scant 1.3 million miles from its native star and boils at 450 ° Fahrenheit. It's unlike any other planet Hubble has spied to date.
Here's one to wrap your head around. This image from the Hubble telescope shows lights from a globular cluster of celestial bodies 10 billion years old. That means those lights were shining five billion years before our solar system was born, and one of the most ancient in the night sky.
