Astronomy Picture Of The Day
Astronomy is a study of outer space. Some people do it for a living, others just to pass the time. So people tend to flock to an astronomy picture of the day. There are so many things to see, that browsing such images will never become boring.
The first place to look for and astronomy picture of the day is NASA’s website. There’s a new image there every day. There’s also another section that shows videos and images. This could be an excellent source for images and videos for your own daily updated site. November 5, 2008 showed a close view of Saturn’s moon Enceladus. It was taken by the Cassini space craft as it passed about 1,700 kilometers from the surface. The image is so detailed that features about the size of a bus are viewable. The ice on this moon reflects nearly 100% of all the light that hits it. Wear sunglasses. Cassini is scheduled for more flybys during its mission.
NASA maintains an archive of all the astronomy photos of the day dating all the way back to June 16 of 1995. That image was of Earth as if it had the density of a neutron star. This photo was created by the computer. One interesting element is that the constellation Orion in his visible twice. That’s because a neutron star is dense enough to bend light from behind it to the front of it. This causes some double vision.
September 8, 1995 brought a very interesting image of the central part of our own Milky Way galaxy from the NASA COBE Satellite. This image would normally not be visible because the dust in the galaxy obscures it in the visible spectrum. But COBE’s infrared imaging captured this amazing image.
January 1, 2000 and January 1, 2001 shared the same image, a drawing really, of the universe as defined in the last millennium. That’s because most people believe the year 2000 was the first year of the new millennium. In reality January 1, 2001 was the beginning of millennium #3. NASA figured it was better to just go with both. the picture now online at http://apod.nasa.gov/apod/ap010101.html is an indication of the universe as it is progressed in the mind of man.
NASA has a lot more days with their own astronomy picture of the day. You’ll find them on NASA’s website.
