Examining objects and phenomena in space such as nebulae, galaxies and comets is Astronomy. It’s important science, but for many people an enjoyable hobby. So people tend to flock to 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 and astronomy picture of the day. There’s a new image there every day. There’s also another section that shows videos and images. This could be used to create your own image site. November 5, 2008 showed a close view of Saturn’s moon Enceladus. The space probe Cassini took this image. It gets down to details the size of the 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 moon is so interesting that Cassini will continue to fly by for more images later in its mission.

NASA’s images of the day go all the way back to June 16, 1995. That image was of Earth as if it had the density of a neutron star. Of course the image is a computer simulation. It shows Orion 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.

NASA’s COBY satellite took a very interesting image of the center of the Milky Way galaxy on September 8, 1995. This area is normally invisible because of the dust obscuring it. 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 astronomy picture of the day. That’s because most people believe the year 2000 was the first year of the new millennium. However the third millennium actually began on January 1, 2001. 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.

There are countless days each with their own astronomy picture of the day. Go to NASA’s website for more.
