APOD 4.6

     This week I was looking at the APOD titled "Massive Nearby Spiral Galaxy NGC 2841". This is a massive galaxy which is only about 46 light-years away. It is found in the constellation Ursa Major. This is called the island nebula and shows a bunch of star forming regions in its spiral arms. This galaxy is about 150,000 light-years long making it even bigger than the milky way galaxy. This picture is a composite taken by the Hubble Space telescope and the Subaru Telescope. The halo around the galaxy is the result of winds and stellar explosions that caused a gas to form near the outside.
