Two Hours Before Neptune - Two hours before closest approach to Neptune in 1989, the Voyager 2 robot spacecraft snapped this picture. Clearly visible for the first time were long light-colored cirrus-type clouds floating high in Neptune’s atmosphere. Shadows of these clouds can even be seen on lower cloud decks. Most of Neptune’s atmosphere is made of hydrogen and helium, which is invisible. Neptune’s blue color therefore comes from smaller amounts of atmospheric methane, which preferentially absorbs red light. Neptune has the fastest winds in the Solar System, with gusts reaching 2000 kilometers per hour. Speculation holds that diamonds may be created in the dense hot conditions that exist under the cloud tops of Uranus and Neptune. (via APOD)

When I was little and obsessively reading all the children’s astronomy books at the library, Jupiter had sixteen moons.

I feel old.

guys it’s 2012 and there was a post on my dash implying that pluto not being a planet anymore is a reason to be upset

guys it’s ok!! pluto has lots of friends. pictured here are five dwarf planets, and in the background are some of the 50-200 more that are thought to be floating around that we haven’t really classified yet.

AHHHH YOU GUYS.

THIS POST.

I JUST.

I LOVE IT SO MUCH.

This is what I always try to tell people, but nobody understands.

Pluto wasn’t exiled, he’s HOME.
