The Colors of IC 1795

http://apod.nasa.gov/apod/ap091210.html

In this picture there are glowing gas and obscuring dust clouds. That appear to be in IC 1795. These glowing gas clouds probably consist or approximately 99% of the interstellar medium is composed of interstellar gas, and of its mass, about 75% is in the form of hydrogen with the remaining 25% as helium. To look for this in the sky you would have to look at the star forming region in the northern constellation Cassiopeia. The colors that are formed are caused by Hubble false-color palette. This means that a lot of pictures were taken of different wavelengths and combined with computers to create this beautiful picture. This picture spans around 70 light-years across IC 1795, the actual image is 6,000 light years away.

Polar Ring Galaxy NGC 660

This picture is of NGC 660. Which is the center of the this intriguing field. It was discovered in 1784 by William Herschel. This galaxy is in the constellation Pisces. This galaxy is about 20 million light-years away. NGC 600 is a polar ring galaxy which means it is a rare type of galaxy with stars, gas and dust orbiting in rings perpendicular to the plane of a flat galactic disk this is cause by the captured debris rotating around a ring. NGC 660's ring are about 40,000 light-years long. This picture is an amazing show of how astronomy can be beautiful and so imformitive about what consists in space.
