In the Fall of 2010 UofA Honor's College students studied the then recent discovery of a supernova explosion in a galaxy called call UGC 5189 located some 160 million light years away. They used the SkyCenter's Schulman telescope to detect the bright "new star" that appeared at the top right of this peculiar galaxy (click on the image below). Calar Alto Observatory, having seen this subsequently published image, requested to use it as a wide-field example of their work.

The German-Spanish Astronomical Center at Calar Alto is located in the Sierra de Los Filabres (Andalucía, Southern Spain) north of Almeria. It is operated jointly by the Max-Planck-Institut für Astronomie (MPIA) in Heidelberg, Germany, and the Instituto de Astrofísica de Andalucía (CSIC) in Granada/Spain. Calar Alto provides three telescopes with apertures of 1.23m, 2.2m and 3.5m to the general community. A 1.5m-telescope, also located on the mountain, is operated under the control of the Observatory of Madrid.

The article Calar Alto Observatory wrote describes this supernova as a rarely captured Type IIn which produces an asymmetric explosion. Studying these kinds of events give astronomers a better understanding of the physics that takes place during the core collapse of massive stars.
