Supernova 1994D in Galaxy NGC 4526, Hubble telescope

A supernova is a stellar explosion caused when the mass of a star's core exceeds the sustainable limit or when nuclear fusion produces more energy than the star can contain. The explosion emits massive amounts of energy. Supernovae are classified as cataclysmic variables, the majority of which are close binary systems. Supernovae show sudden, dramatic, and final magnitude increases of 20 magnitudes or more, compared to a regular nova, which typically brighten 7 to 16 magnitudes.

The data collected below comes from multiple sources and leverages the numbering convention utilized by the IAU Central Bureau for Astronomical Telegrams. I've compiled photos by searching the internet, and other sites such as the ASRAS, Astronomy Section, Rochester Academy of Science.

I'm cataloging these primarily as a personal education tool, and to begin tracking supernova I have photographed.

SN 2014J is a type Ia supernova in Messier 82, and was discovered in mid-January 2014. It is the closest type-Ia supernova discovered in the past 42 years. The last supernova that was unambiguously closer to Earth than SN 2014J was SN 2004dj, which was of Type II-P supernova. This supernova occurred in the galaxy NGC 2403. Due to the brightneszs of this supernova, many automated search programs which search for supernovas actually ignored this one (assuming error). It was discovered accidentally during an undergraduate teaching session at University of London Observatory. I shot this on January 29th, two days before SN2014J stopped brightening, which reached its peak brightness at magnitude 10.5.
