Massive stars that end their lives as supernovae are surrounded by a cloud of matter that causes their brightness to decrease significantly before they explode. Astronomers have found that this process occurs over a short period of time, usually several months, which can predict the onset of a supernova. A recent study by astronomers from France and Great Britain focused on Type II-P supernovae, which involve the sudden dumping of matter by a star before it explodes. By comparing simulation results with archival images of previous supernovae, the researchers found that the formation of the cloud is rapid, taking in some cases less than a year. This discovery gives hope that scientists will be able to predict some supernova explosions in advance by observing the rapid enveloping and fading of red supergiant stars.
