In 2024 , a nova explosion in the star system called T Coronae Borealis , or T CrB, will once again be visible to people on Earth .

It will appear 1,500 times brighter than usual, but it won’t be as spectacular as the event in 1054 .

The event occurred over 2,000 years ago , but its light will just be reaching us later this year .

It might take some effort to find, but if you have time, you’ll witness a rare event.

The white dwarf’s exploding hydrogen envelope will brighten to a magnitude 2 or 3 .

It will briefly become the brightest star in Corona Borealis .

This maximum brightness will last only several hours , and T CrB will fade from visibility with the naked eye in a matter of days.
