Astronomy Picture Of The Day
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 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. It also has a multimedia center with video and images. This could be an excellent source for images and videos for your own daily updated site. Saturn’s moon Enceladus was featured on November 5, 2008. The photo was taken by a passing spacecraft. The image is so detailed that features about the size of a bus are viewable. 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.
June 16, 1995 the first astronomy photo of the day NASA has online. It was a representation of the earth as if it were as dense as a neutron star. Of course the image is a computer simulation. 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. That’s why some objects are seen twice.
NASA’s COBY satellite took a very interesting image of the center of the Milky Way galaxy on September 8, 1995. 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, 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. However the third millennium actually began on January 1, 2001. 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.
There are countless days each with their own astronomy picture of the day. Go to NASA’s website for more.
