Astronomers aim to understand what types of stars produce different kinds of explosions.

In 2009 , astronomers observed a bright event 65 million light years away that on first impressions resembled a supernova explosion.

But the explosion did not brighten as expected and was reclassified shortly after discovery as a "supernova impostor" Scientists already monitor volcanoes, measuring changes in activity to predict an upcoming eruption.

At Stockholm University , our team is using telescopes from the European Southern Observatory and the Zwicky Transient Facility to identify the signs that indicate a star is nearing the end of its life.

By recognizing these signals, we can alert the scientific community and be ready to watch as a star experiences its final, dramatic moments.
