Description

The Grus-Quartet of interacting spiral galaxies; NGC 7552, 7582, 7590 and 7599

Taken on the island of La Palma during my vacation in October 2015. At -42 degrees southern declination an impossible target from my usual site in Vienna.

At 11th-magnitude, NGC 7552 is about 75 million light years away. Given its apparent size of 3.4 by 2.7 arcmin, it is about 75 thousand light years across. NGC 7552 and 7582 are exhibiting high starburst activity; this is thought to have arisen because of the tidal forces from interacting.
