The event, known as a nova, will be so bright that a “new” star will seem to appear in the night sky temporarily, visible to the naked eye.

A rare cosmic eruption is expected to occur in the Milky Way in the coming months — an outburst so bright that a “new” star will seemingly appear for a short time in the night sky.

The event, known as a nova, will be a once-in-a-lifetime skywatching opportunity for those in the Northern Hemisphere, according to NASA, because the types of star systems in which such explosions occur are not common in our galaxy.

The stellar eruption will take place in a system called T Coronae Borealis, which is 3,000 light-years away from Earth. It contains two stars: a dead star, also known as a “white dwarf,” closely orbited by a red giant. Red giants are dying stars that are running out of hydrogen fuel in their cores; the sun in our solar system will eventually become one, according to NASA.

That is crazy. And some stars are probably exploding right now and it will only be visible by our descendants in a few thousands of years. They will look like at it wondering how it was to live in our times.
