T Coroni Borealis: A Stellar Phenomenon

What astronomical event is caused by the white dwarf in the T Coroni Borealis system reaching a critical threshold?

How often has the Nova of T Coroni Borealis been observed historically?

What is the best condition for observing the Nova of T Coroni Borealis?

Which constellation contains the T Coroni Borealis system?

What additional celestial event is mentioned alongside the Nova and involves the moon's shadow on Earth?

T Coroni Borealis

T Coroni Borealis is a binary star system 3,000 light-years away
The system consists of a white dwarf and a red giant
The white dwarf accretes material from the red giant
This process causes the white dwarf to reach a critical threshold, leading to a thermonuclear explosion
The explosion is what causes the Nova to be visible from Earth as a bright new star
The phenomenon has been observed approximately every 80 years, with the last grand display observed in 1946.

Observing T Coroni Borealis

The Nova is located in the constellation Corona Borealis
The constellation resembles a crown and is visible near Vega and Arcturus
The best time to observe the event is on a cloudless moonless night
To minimize light pollution, observe from a dark location away from city lights
Use star maps and astronomical apps for guidance
Allow your eyes to adjust to the darkness for at least 30 minutes to maximize visibility.

Other Notable Celestial Events
