In July 1054, court astronomers in China recorded a new "guest star" near Tianguan, the star we now call Zeta Tauri.

Born, like other comic book characters, out of an otherwise trivial but life-changing animal bite, the Rabid Librarian seeks out strange, useless facts, raves about real and perceived injustices, and seeks to meet her greatest challenge of all--her own life.

You can see both Earth and Moon. Yay! (PS, the only alteration on the screenshots was that I mucked with a couple of the icons in the folders for the finances folder. You don't really need to know who I bank with, etc.)
Especially purses and clothes, but also desktops. So both my laptop and my desktop at home, as well as my desktop at work, have the Milky Way theme for Windows, and my phone has the Earth & Moon Pro live wallpaper as well, as seen on the screenshot here. Funny, I tried the 'I'm feeling lucky' button on Google today and it took me to photos from the Hubble telescope. I am in a starry mood this week. I do love astronomy. :)
I'm tempted to take my telescope out for viewing. For one thing, I can actually see the North Star from my apartment, which is not so common, and which the telescope uses to go to all other positions in its database. For another, Mars is extremely clear just to the naked eye. But, alas, it is late. I'm very tempted to join a local astronomy club (Bluegrass Amateur Astronomy Club) that meets monthly out at the Raven Run Nature Sanctuary to view the sky through telescopes. I think I would learn a lot, and it's just $10 a year. The next viewing date is Saturday. :)
NASA's James Webb telescope, the successor to the Hubble, is on the chopping block. With the U.S. Congress arguing over fiscal matters, one of the things that may get cut is NASA's budget, with the expensive James Webb telescope potentially getting the ax. If that happens, a generation of scientific discoveries about the nature of the universe may need to be put on hold.
Right now the future of the Webb telescope, scheduled to launch in 2018, is uncertain. Congress is looking to cut costs, and NASA's budget could be cut by as much as $1.6 billion (or about nine percent of its overall budget). Such a big cut would certainly be the death knell for the Webb telescope, which has so far cost $3 billion but whose final price is expected to hit the $6.8-billion mark.
It's a question that many people who popularize astronomy get asked time and again: "How many stars are there?" And while the sky is packed with a myriad of stars, the number visible to skywatchers depends greatly on the local night sky and the impact of city lights.(NASA image of light use around the world.)
With Earth Hour 2011 set for 8:30 p.m. local time on Saturday (March 26), now is an opportune time to take a look at the impact of light pollution on the night sky. Earth Hour is a movement that encourages the public to switch off their lights for one hour to conserve power and take a stand against climate change.
We cast this message into the cosmos… Of the 200 billion stars in the Milky Way galaxy, some — perhaps many — may have inhabited planets and space faring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: We are trying to survive our time so we may live into yours. We hope some day, having solved the problems we face, to join a community of Galactic Civilizations. This record represents our hope and our determination and our goodwill in a vast and awesome universe.
