This is an example of a good candidate discovered on Supernova Sighting. The left frame is a recent image of the galaxy, the middle frame is an older image, and the right frame is the difference between the two showing what’s changed, a lovely, bright supernova!
We’re very excited to announce the return of Supernova Sighting today as part of ABC Stargazing Live! Over the next 24 hours we plan to find as many supernova candidates as possible, and announce them on live TV in Australia. Make an astronomical discovery today at www.supernovasighting.org.
