The eruption of T Coronae Borealis (T CrB) is an eagerly anticipated celestial event. This star undergoes a thermonuclear detonation on its surface approximately every 80 years, making it visible without the need for any aid for the first time since the 1940s. The best view of the event will be looking south-south-west from London around 2300 BST. It is recommended to keep an eye on this location.
The Astronomical League advises making a sketch of the constellation now and then another when the star erupts. Drawing the constellation now will assist in determining the exact day when the light from the eruption arrives at Earth. However, despite our anticipation, the actual explosion of the star has already occurred. T CrB is situated about 2,600 light years away, which implies that the light we are eagerly awaiting exploded from the star approximately 2,600 years ago and has been traversing through space ever since. It is now only a matter of weeks, or even just days, before we witness this remarkable event.
For observers in Sydney, Australia, the constellation will be most visible when at its highest point, which is due north at around 2100 AEST. Take this opportunity to witness this rare celestial event and savor the moment when the light from the eruption finally reaches us after its long journey through space.
