Planetary Nebula (NGC 6210), Jasmin Elmers

Planetary Nebula NGC6210

NGC6210 is a planetary nebula, some call it the Turtle Nebula. A planetary nebula is material thrown off by a star that has run out of hydrogen fuel to burn, is consists of a glowing shel off gas and plasma that is formed by certain types of stars when they die. This particular nebula is called the turtle nebula because when shown a good picture (like a picture taken from the Hubble Space Telescope) some say it looks like a giant turtle. This nebula lies around 6,500 lightyears away from the earth and is located in the constellation Hercules.

NGC6210 or the Turtle Nebula's surface brightness is very high which makes it easier for small scopes to see.  This nebula is 0.6 arcminutes and has a linear size of 1.1 light years. It appears as a small, round, blue-green disk for smaller telescopes and with larger instruments you may see a faint outer shell. Most pictures of the NGC6210 are red or they are green and yellow with a little red and blue. Some pictures show a cross-like shape of the nebula; this just goes to show how God's glory is seen in all of creation, even 6,500 light years away.
