Milky Way's Twin: The Island Galaxy of Pegasus
We bet it does. Spiral galaxy NGC 7331, located 49 mega light years distant in the constellation Pegasus, is often touted as an analog to our own Milky Way. When the Daily Galaxy staff views the ethereal beauty of the object, we are inspired to wonder: what lies within; what mysteries life forms make this island in the cosmos their home? Since the galaxy's disk is inclined to our line-of-sight, long telescopic exposures often result in an image that evokes a strong sense of depth. The effect is further enhanced in this well-framed view by the galaxies that lie beyond this beautiful island universe. The background galaxies are about one tenth the apparent size of NGC 7331 and lie roughly ten times farther.
I welcome your friendship in peace, love and light and welcome dear friend to join my social network for questions about Islam and Quran if u are interested or if there are any misunderstandings or misconceptions about them. http://afifichestclinic.ning.com/
