Astronomy Picture Of The Day
By Henry Diaz
This Article is all about the topic that you have been looking for, take your time to read.
The study of space objects such as planets, galaxies and stars is Astronomy. Some people do it for a living, others just to pass the time. That's why when a web site or magazine offers an picture of the day it's likely to garner a great deal of attention. There are so many things to see, that browsing such images will never become boring.
NASA of course is a primary source for an picture of the day. This site NASA.gov shows a new image each and every day. There's also another section that shows videos and images. This could be used to create your own image site. On November 5, 2008, NASA's picture of the day was a close view of Saturn's moon, Enceladus. The photo was taken by a passing spacecraft. The image is crisp enough to see a small bus, if there were one on the moon. The ice on this moon reflects nearly 100% of all the light that hits it. Talk about bright. The plan is that Cassini will take more images of this moon later in its mission.
NASA maintains an archive of all the photos of the day dating all the way back to June 16 of 1995. It was a what if image of the Earth posing as a neutron star. Of course the image is a computer simulation. The most interesting feature is that the constellation Orion is 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 was an amazing image of the central part of the Milky Way galaxy taken by NASA's COBE satellite. Due to space dust this would normally not be visible to the naked eye or to a telescope. But COBE scans in infrared, so produced the amazing image of our very symmetrical galaxy.
January 1 in 2000 and 2001 had the very same picture of the day. It's due to the fact that many people think of the year 2000 as the first day 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 http://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.
It would be very hard to see each and every picture of the day. Visit the web site, NASA.gov, to see them.

Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. ~Samuel Ullman
