Stargazers across the globe may get the chance to see a "once-in-a-lifetime" cosmic event this summer when an exploding star system could light up the night sky. (7th/June/2024 )
A nova explosion of the binary star system T Corona Borealis (T CrB) is predicted to take place any time from until September and will be so bright will be visible from Earth with the naked eye.
This is an extremely rare event: the T Coronae Borealis nova was last seen from Earth in 1946.
What exactly is a nova explosion, and when and where will we be able to spot it?
What's going to cause the nova explosion?
Within the Northern Crown constellation is a star system called T Coronae Borealis, also known as the "Blaze Star".
It is 3,000 light years away from Earth, and is made up of two types of star. One, a white dwarf, is an earth-sized dead star, and the other is an ancient red giant.
The gravitational pull of the white dwarf gradually strips away hydrogen from the red giant.
Eventually, this build up of gas triggers a huge thermonuclear explosion, known as a nova explosion.
