The Antennae Galaxies, Jared Eliason


The Antennae galaxies, while it may appear to be one swirling galaxy, is a pair of two galaxies in the constellation Corvus. Both of these galaxies were discovered 1785 by Friedrich Wilhelm Herschel. The name Antennae comes from the tails of both galaxies which are stars, dust, and gas thrown from the collision of the galaxies, the tails resembling the antennae of an insect. These two galaxies are in a galactic collision and will eventually form a supergalaxy. The Antennae galaxies are about 68 million light years away from earth

professional image:

The image above (the professional image) is what it should look like. Sadly, my image pails in comparison but I put this image on this page to more accurately explain what is going on. The clouded areas around the two galaxies are mostly dust and gas. The blue specks are millions of stars, some clustered together. The large orange areas are the concentrate nuclei of billions of stars. One thing to note when considering this image is that there used to be two separate spiral galaxies, accounting for the circular motion around the nuclei. The two galaxies are NGC 4038 (left), that used to be a spiral galaxy and NGC 4039 (right), that used to be a barred spiral galaxy. These two galaxies used to be completely separate galaxies but now they have merged and will eventually ("billion" of years) become a supergalaxy. . Although my image is not as detailed as the brilliant professional image it was still awesome to analyze something that God created to dazzle us.
