The compact white #dwarf has an immense gravitational pull, so great that it steals material away from its larger neighbour.

"The #gravity on the surface of the white dwarf is a million times the gravity we feel on Earth, so if we stood on it, we would be crushed instantly"

The material it grabs from the other star gets crushed and compressed - until eventually it triggers a nuclear #explosion, releasing 💥 a huge amount of energy https://www.bbc.com/news/articles/c140exemgk7o

Stellares Himmelsschauspiel: In den nächsten Tagen oder Wochen wird am Himmel eine Nova aufleuchten – die Explosion eines Weißen Zwergs im Sternbild „Nördliche Krone“. Diese Nova wird mit bloßem Auge sichtbar sein – und es könnte jeden Moment soweit sein. Was aber ist eine Nova? Was wird dabei zu sehen sein? Und was ist an […]

Prossimamente è prevista l'esplosione della nova ricorrente T Coronae Borealis (T CrB)

T CrB è una stella binaria, composta da una nana bianca (i resti del nucleo di una stella al termine della sua "vita") e da una gigante rossa (una stella nelle ultime fasi della sua evoluzione)

NOVA T CrB IS ABOUT TO EXPLODE: We've been talking about this one for a while and it could happen at any moment. Recurrent nova T CrB in the constellation Corona Borealis is poised on the knife edge of a once-in-a-lifetime explosion. "It's due to go nova right about now," says a leading expert. The explosion should be visible to the naked eye even from light-polluted cities.

https://Spaceweather.com has some tips to watch it blow. Image: An infographic created by South Korean astronomer Bum-Suk Yeom shows where the nova will occur in Corona Borealis.
