New Pictures of Hoag’s Object!
News story originally written on September 12, 2002
The Hubble Space Telescope has recently taken some exciting pictures of Hoag’s Object, a mysterious galaxy 600 million light years from Earth.
The galaxy was named after Art Hoag, the astronomer who found it in 1950. Located in the constellation Serpens, Hoag’s Object is about the size of our galaxy but it has an unusual shape with a blue ring of young stars and a yellow center of older stars. It is so unusual, in fact, that Art Hoag did not know it was a galaxy when he first found it.
Hoag’s Object is unlike other ring shaped galaxies, which often form by collision with another galaxy, because it shows no signs of collision. Astronomers suspect that the outer ring of stars was formed two to three billion years ago when a galaxy passing nearby left young stars behind.
