NGC 5033

NGC 5033 is a sprawling spiral galaxy with thick insect-like arms. Several HII (pink star forming regions) can be seen in this image. This galaxy is estimated to be 37 million light years away. Although it is a faint galaxy (at least for a 0.5m telescope) it is surprisingly well-studied. One of the most interesting characteristics of this galaxy is that it is classified as being a Seyfert type. The nucleus (and small sources within) is extremely luminous and varies in brightness. Astronomers have also found that this galaxy contains twice the abundance of oxygen than our own solar neighborhood.
