ASASSN-15LH: Astronomers Have Found the Brightest Supernova Yet

The record-breaking supernova ASASSN-15lh as it would appear from an exoplanet about 10,000 light-years away.
Picked up by a night-sky survey, the explosion happened 3.8 billion light years from Earth.
At that distance, the blast was 22,700 times dimmer than the faintest objects a human can see with the naked eye. But the far-flung supernova was so powerful that astronomers calculate if it had happened at the distance of the famed "dog star" Sirius, just 8 light-years away, it would have been as bright as the sun. -- Smithsonian

Your Say

If it were 'only' 8 light years away it would be as bright as the sun ... and we would all be dead.
