Astronomy: Screensaver
Astronomy is the study of the universe. It is a serious science, but also a very pleasurable hobby. Therefore, whenever an astronomy picture of the day is offered to people, they usually welcome it. There are plenty of such pictures to choose from, and plenty of interesting objects out there to keep people looking.
Of course ,NASA is one of the primary sources for an astronomy picture of the day. This site, NASA.gov, shows a new image each and every day. There is also a section that shows films. These could be used to create your own image site. For example, Saturn's moon Enceladus was the feature with "star billing" on November 5, 2008.
This picture was taken by a passing rocket. It can reproduce details the size of a bus. The ice on this moon reflects as glare, nearly 100% of all the sun light that hits it. So you would need to wear sunglasses! This moon is so interesting that Cassini will continue to fly by for more photos later on in its mission.
NASA maintains an archive of all the astronomy picture of the day dating all the way back to June 16 of 1995. It was a 'what if' photo of the Earth posing as a neutron star. The picture is a computer generation. The most interesting feature is that the constellation Orion is visible twice. Even light from behind a neutron star is visible because the dense star bends the light all the way around it. This causes some double vision.
September 8, 1995 was an amazing photo of the central part of the Milky Way galaxy taken by NASA's COBE satellite. This area is normally invisible because of the dust obscuring it. But COBE scans in infrared, so produced that fantastic photo of our very symmetrical galaxy.
The astronomy picture of the day was the same on January 1, 2000 and January 1, 2001. The reason both dates shared this photo is that most people considered the year 2000 as the first year of the third millennium.
However, the third millennium actually started on January 1st, 2001. NASA reasoned it was just better to just go with the flow and do it on both dates. apod.nasa.gov/apod/ap010101.html displays mankind's view of the galaxy as it grew from mere objects circling the Earth, all the way to the 'Big Bang' creating the universe as we see it today.
NASA has a lot more days with their own astronomy picture of the day. Visit the web site, NASA.gov to see them. - 2368
