A warning system for when stars go supernova

In Oblivion, humanity is attempting to recover from a narrowly won war with an alien species. We survived, but the planet is wrecked and the only hope — at least according to the authorities — is to leave Earth behind. As the movie opens, that’s what we think is happening. In truth, the conflict is ongoing. The space station ferrying humanity off-world is actually an alien craft stealing the last of humanity’s resources before they leave.
Scientists have devised a supernova warning system, a way of detecting supernovae before they happen.
