News: Milky Way Over Abandoned Kilns

From Astronomy Picture of the Day, Milky Way Over Abandoned Kilns by Tom McEwan. McEwan shot some historic kilns in rural Nevada, stitching together a panoramic "digital conglomerate of five separate images taken in early June from the same location. Visible above the unusual kilns is a colorful star field, highlighted by the central band of our Milky Way Galaxy appearing along a diagonal toward the lower right."

How To: Find and Observe the Garradd Comet

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...

Earth's Shadow: Time-Lapse Video of the Total Lunar Eclipse of 12/10/11

I woke up at 4:00 am this morning in order to take some video of the last total lunar eclipse visible from North America till 2014. The eclipse was beautiful. It was amazing to watch the shadow of our planet creep slowly across our nearest neighbor. Once the shadow was blocking out most of the light from the sun, the moon was significantly dimmer and the color had changed to a reddish orange. This color is caused by the same effect that makes our sunrises and sunsets so colorful. The light fr...

News: Proof of Water on Mars

Since the first time we've been to Mars, the question was 'Did there used to be life here?'. That all changed for the better when NASA told us that the Opportunity rover found signs of water- the essential part to life. NASA officials on Wednesday said the rover discovered a mineral vein of gypsum running along the rim of a crater called Endeavor. The gypsum was deposited by flowing water billions of years ago. The vein is about 20 inches long. They found it while studying a rock called Tisda...

News: Welcome to Astronomy World!

A little about myself and astronomy: I created this world because I love astronomy. I really, really, love astronomy. When I was ten, I went to a restaurant and saw a huge wall mural of the Andromeda Galaxy. At my house, we had a tiny refractor telescope. I knew this wasn't enough, so I bought (with help) an 8 inch Dobsonian reflector. I looked up one time to try to find something to look at and saw something fuzzy- the Orion Nebula. This is when I really got into using my telescope. I still ...
