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.
never heard of these recurrent novae, got to look it up, sounds counterintuitive
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.
ah, i see, the word super makes all the difference here
There’s also a hypernova. :D
🤯
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.
Thank you for posting the bit and the link.
Holy fuck that’s so much energy!
Like when Bowie and Frankie made Under Pressure?
terra nova as well, which is when you boot up civ V

Without reading the article, I imagine it’s a binary system where a white dwarf is siphoning gases from a star. When it reaches critical mass, it goes thermonuclear.
You are exactly right - how could this have possibly been a guess, lol.
I saw a video on this and this is pretty much how I remember it explained.
How is it counterintuitive? Gas builds up, goes boom, repeat.
Usually stars don’t build up gas. This one is part of a binary system, though, so like the other comment says, it’s siphoning matter from the other one.
the counterintuitive part came for the standard candle supernovae already coming from binary systems and not being recurring, but somehow the recurrent ones manages to blow up with 1/100 of the energy, i am just learning this
