Nova Outburst in 2024

A nova is a sudden, dramatic increase in brightness in a binary star system.
It occurs in systems with a "dying" red giant star and a "dead" white dwarf star.
Material from the red giant accumulates on the white dwarf.
Eventually, the accumulated material explodes, causing the nova.
Usually visible only with telescopes.
T Coronae Borealis (T CrB) is a notable example, known for periodic nova outbursts.
T CrB is a binary star system, 3,000 light-years away.
T CrB novae occur roughly every 80 years, with the last one in 1946.
The red giant sheds material onto the white dwarf as it heats.
This causes the white dwarf's atmosphere to heat and explode.
The white dwarf survives the nova event.
The next nova eruption for T CrB is predicted to happen sometime before September 2024.
The exact timing is uncertain, but could occur in the next few months.
The nova will be visible to the naked eye for several days.
It will be visible with binoculars for just over a week.

Observing the Nova

The upcoming nova outburst is different from the solar eclipse: it's visible with no equipment required, anywhere on Earth.
The event will appear as a bright star in the Northern sky.
