About 40 million light years distant is the spiral galaxy NGC 7331. It is located in the constellation Pegasus. It is part of a larger visual group of galaxies some of which can be seen in this image including four below the big spiral and another four hovering in the upper right of this frame. These much smaller appearing galaxies are actually quite distant, almost an order of magnitude distant: they are estimated to range between 300 and 350 million light years away. This image is the result of 165 minutes of imaging in a dark sky location in the west desert. #Astronomy #Astrophysics #Cosmology #AstroPhotography #ExploreScientific #ZWOCameras #asiairpro #ASI533 #clayhausphotography #galaxy #galaxies #ngc7331 https://www.instagram.com/p/CT-hiC9hZbn/?utm_medium=tumblr

NGC 7331- This is a spiral galaxy very similar to the Milky Way Galaxy and is often referred to as the Milky Way Galaxy’s twin.  

Explanation: This wide, sharp telescopic view reveals galaxies scattered beyond the stars of the Milky Way at the northern boundary of the high-flying constellation Pegasus. Prominent at the upper right is NGC 7331. A mere 50 million light-years away, the large spiral is one of the brighter galaxies not included in Charles Messier's famous 18th century catalog. The disturbed looking group of galaxies at the lower left is well-known as Stephan's Quintet. About 300 million light-years distant, the quintet dramatically illustrates a multiple galaxy collision, its powerful, ongoing interactions posed for a brief cosmic snapshot. On the sky, the quintet and NGC 7331 are separated by about half a degree.
