Don’t Miss the T CrB Star Explosion

By /
A red giant star and white dwarf orbit each other in this animation of a nova similar to T Coronae Borealis. The red giant is a large sphere in shades of red, orange, and white, with the side facing the white dwarf the lightest shades. The white dwarf is hidden in a bright glow of white and yellows, which represent an accretion disk around the star. A stream of material, shown as a diffuse cloud of red, flows from the red giant to the white dwarf. When the red giant moves behind the white dwarf, a nova explosion on the white dwarf ignites, creating a ball of ejected nova material shown in pale orange. After the fog of material clears, a small white spot remains, indicating that the white dwarf has survived the explosion.

T Coronae Borealis, or T CrB, is a binary star system set to explode in a spectacular nova. Located 3,000 light-years from Earth, T CrB usually remains too dim to see but will soon shine as brightly as Polaris. This rare event, expected by September 2024, offers a unique stargazing opportunity. The star system, comprising a white dwarf and a red giant, undergoes a nova every 80 years. The nova will be visible for less than a week and is anticipated to reach a magnitude of +2. Astronomers are eager to study this event closely using various telescopes.
