T Coronae Borealis (T CrB), the star currently anticipated to undergo a thermonuclear detonation on its surface, is set to be visible to the human eye without the need for any aids. This sighting, not seen since the 1940s, will occur roughly every 80 years and will make the star shine as brightly as Alphecca, the brightest star in the Corona Borealis constellation. The Astronomical League encourages individuals to sketch the constellation now and again when the star eventually erupts, which will aid in pinpointing the exact time when the eruption’s light reaches Earth.
For those observing from Sydney, Australia, the constellation will reach its highest point due north around 2100 AEST. This positioning will provide an optimal view of the celestial event and allow for a unique perspective on this rare occurrence. Although technically an explosion has already occurred, T CrB is located an immense 2,600 light years away. As a result, it will take centuries for its light to reach Earth. However, with only weeks or days left until we witness it here on Earth, now is an ideal time to start preparing for this rare cosmic event.
