NGC 5917 - Interacting Spiral Galaxy

In this image, taken by the Hubble Space Telescope, you can see NGC 5917. It is a spiral galaxy, located in the constellation of Libra (, about 87 million light-years away from Earth. It has a diameter of roughly 40,000 light-years.

NGC 5917 is pulling matter off of MCG-01-39-003, another galaxy which can't be seen in this image (Take a look at the ESO link for an image of both). Galaxies showing this behavior are called interacting galaxies ( And although the galaxy looks a little bit distorted, the spiral structure can still be clearly seen in this image. At some point in the future NGC 5917 might merge with its neighbor MCG-01-39-003 in what is called a galaxy merger (

NGC 5917 was discovered July 16th, 1835, by the English astronomer John Herschel (
