One of the most spectacular phenomena in space is a nebula. A nebula is an interstellar cloud that is made up of dust, hydrogen and helium gas, and plasma. It is formed when portions of the interstellar medium collapse and clump together due to the gravitational attraction of the particles that comprise them. To the average observer they look like a huge, colored blob floating in space. |
This is picture of the Cat’s Eye Nebula, a planetary nebula in the constellation Draco. This used to be a star similar to our Sun, but then it died and became a white dwarf, puffing off its outer layers into space.
This is the Carina Nebula, a star forming nebula in the Carina Constellation. It holds Eta Carinae, one of the most massive stars ever discovered, which is expected to detonate as a supernova in the next few hundred thousand years.
This is the Bubble Nebula, also known as NGC 7635. This nebula glows because of a hot central star that’s providing radiation and exciting the nebula atoms.
This is a picture of the Trifid Nebula taken by the European Southern Observatory. This nebula was cataloged M 20 by Charles Messier as part of his famous catalog. It’s called the “Trifid Nebula”, because it appears to be broken up into three parts.
