Identifying a Supernova

Using Rubin data, astronomers will be able to measure the distance to the supernova and determine the redshift of its host galaxy.

Because supernovae often appear where no star was previously visible, they can be spotted by comparing images of the host galaxy taken at different times.

The images on this page show a supernova discovered in a galaxy. Can you find it? When you spot the supernova, click on it. If you have identified it correctly, a circle will appear around it.
