M106 Galaxy, Marcus Koornneef


This is the M106 Galaxy; it is a large spiral galaxy very similar to our own Milky Way Galaxy. Viewing M106 from Earth we see it at a slight angle and at an inclination. It is classified as "normal" spiral of type Sb . It is suspected to be part of the Ursa Major galaxy group and is located in the constellation Canes Venatici. M106 is approximately 25 million light years away from us and approximately 145443 light years in diameter. For the distance that this galaxy is from Earth it is relatively bright with a magnitude of 8.4, this makes it relatively easy to view with a small telescope. M106 is also a Seyfert galaxy, showing strong emission lines in spectra of its nucleus.

This image of galaxy M106 you can clearly see the two spiral arms that start it the core and wrap around the galaxy as they spiral out. The large dust clouds can also be seen where the gas and dust are between the two spiral arms. The core is very bright and studies have shown that there is a massive black hole at the center, pulling in everything around it. This image was taken in a clear filter, but with other filters bright blue "knots" groups of hot young stars can been seen at the ends of the spirals.
