NGC 6946 – The Fireworks Galaxy

The galaxy NGC 6946 is around 25 million light years away located on the boundary of the constellations Cepheus and Cygnus. The Fireworks Galaxy is about half the size of the Milky Way.

Upon closer inspection of the image, you will notice a strange bright spot located above and to the right of the galaxy core. At first, it looks like a flaw in the image, but it is actually identified as the Red Ellipse (appears blue in the image). This area could be a super bubble or a supernova remnant. As for now, it is still unknown.

NGC 5033 – Spiral Galaxy in Canes Venatici

The galaxy NGC 5033 is somewhere between 40-60 million light years away. From initial observations, it looks pretty bland when compared to the amazing galaxies of M51 – The Whirlpool Galaxy or M63 – The Sunflower Galaxy. When we take a closer look, a few things become visible.

First, in the core of NGC 5033 is a very visible emission band (dark patch). This is most likely caused by extremely hot gas around the galaxy’s supermassive black hole.

NGC 2403 – A Galaxy in Camelopardalis

The galaxy NGC 2403 (Caldwell 7), doesn’t have a special name. It isn’t flashy like M51 – The Whirlpool Galaxy or M63 – The Sunflower Galaxy, but it is fairly close to our Milky Way Galaxy. It lies 8 million light years away. Many of the redder areas of the galaxy are active star forming regions, which show up with a hydrogen-alpha filter.

NGC 2403 is a member of the M81 Local Group of galaxies, which includes the galaxies M81 and M82 in Ursa Major.

M51 – Whirlpool Galaxy

M51 (NGC 5194) is a spiral galaxy in the constellation Canes Venatici (Hunting Dogs). In the image, one can see M51 interacting with the dwarf galaxy NGC 5195. The galaxy is fairly close (31 million light years away), which helps make the galaxy appear larger and brighter. Because of this, M51 is a very popular target for astrophotographers.

M51 is in a group of galaxies bound together by gravity. The group called The M51 Group (because M51 is the biggest/brightest of the group) also includes the galaxy M63 – The Sunflower Galaxy.
