Object: NGC 5128 and SN 2016adj

About 10 million years ago in a galaxy far away a massive star ended its life in a spectacular explosion classified by astronomers as a Type IIb supernova. On 08 February 2016, Peter Marples and Greg Bock of the Backyard Observatory Supernova Search team in Queensland, Australia captured the first glimmer of light from this event to reach the Earth, supernova 2016adj in the great southern galaxy NGC 5128 (Centaurus A). Type II supernovae are characterized by the presence of hydrogen in their spectra and are generated by the core collapse of a massive star ending its life with the property of at least 8 solar masses.

Alerted to this transient phenomenon by our colleague Mike Long, who happened to be on site at the Las Campanas Observatory in Chile, Howard Hedlund of Astro-Physics Inc. and I collaborated on an observing run to capture this supernova, identified by tic marks in the above image.

Our image was used as an inset to a Hubble image of Centaurus A that became NASA’s Astronomy Picture of the Day on 23 February 2016 (http://apod.nasa.gov/apod/ap160223.html).
