In the second half of 2024, a nova explosion in the star system called T Coronae Borealis, or T CrB, will once again be visible to people on Earth. T CrB will appear 1,500 times brighter than usual, but it won’t be as spectacular as the event in 1054.

You're thinking supernova, which happens only once. Novae were seen first as stars that would flare up, becoming a "new" star if it was too faint before to see. They are always a binary system, with the recurrent ones being a companion star that passes by periodically to deposit more material to flare up.

And kilonova, which is when two neutron stars collide!

What is kilonova explained?

A kilonova is an explosion resulting from the collision of two neutron stars, or a neutron star and a black hole. These events are extremely energetic, and can release as much energy in a few seconds as our Sun will produce in its entire 10-billion-year lifetime.
