http://www.gizmag.com/hawaii-megapixel-telescope-asteroids/15511/a very large resolution telescope that sits on top of a hawai'i volcano has been successfully booted. this 1400 megapixel telescope "pan-starrs" is designed to photograph and find earthbound asteroids on an impact trajectory. this is quite a technological marvel. as you read the article you find how advanced and complicated this telescope really is!
"If you were inclined to print out an image captured by the Pan-STARRS telescope as a 300-dpi photograph it would be large enough to cover half a basketball court. And, because PS1 captures an image every 30 seconds you would need to stock up on 1,000 DVDs every night to store the data."
