Astronomy: A Picture of the Day!
By Colin Jones of The Real Way.com
Astronomy is the study of outer space. It's an important science, but for many people an enjoyable hobby. So people tend to like to see an astronomy picture of the day. There are plenty of such pictures to choose from, and plenty of interesting objects out there to keep people looking. NASA is a great source to find an astronomy picture of the day. There's a new image there every day. It also has a multimedia center with video and images. These could be great sources for a person to create their own site that offers a new image each day. November 5, 2008 showed a close-up view of Saturn's moon Enceladus. It was taken by the Cassini space craft as it passed about 1,700 kilometers from the surface. It gets down to details the size of a bus. One interesting feature of the ice on Enceladus is that it reflects 99% of the light that falls onto it. Talk about snow blind. The plan is that Cassini will take more images of this moon later in 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 computer. It shows Orion visible twice. The reason is that a Neutron star is so dense that light, even from behind the star, is visible as it is pulled around by the intense gravity. 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 area is normally invisible because of the dust obscuring it. But COBE's infrared imaging captured this amazing image. The astronomy picture of the day was the same on January 1, 2000 and January 1, 2001. The reason both dates shared this image is that most people considered the year 2000 as the first year of the third millennium. In reality January 1, 2001 was the beginning of millennium #3. Instead of arguing NASA used both dates. The image found at apod.nasa.gov/apod/ap010101.html shows the progression of our picture of the universe from orbs that rotate around the Earth all the way to the big bang event creating an ever expanding cosmos. NASA has a lot more days with their own astronomy picture of the day. Go to NASA's website for more.
