Astronomers are searching for ways to identify stars that are about to go supernova so they can watch the event unfold in real-time and gain insights into these enormous explosions.
Finding such a star is no easy task but scientists have been successful in some cases by observing the star's behaviour in real-time before the explosion.
Astronomers hope that the forthcoming Vera C. Rubin Observatory will aid their search for supernova precursors.
Massive stars can undergo great eruptions, which might be mistaken for supernovas but they ultimately do not destroy the star.
Observing these pre-supernova eruptions offers scientists a rare opportunity to uncover the mysteries of supernova explosions.
One compelling hypothesis suggests that interaction with multiple stars may account for the changes in brightness, signalling the approach of a star's final moments.
In 2025, the Vera C. Rubin Observatory will begin to study these events, providing opportunities to search for fainter precursor activity.
By recognizing the signals that indicate a star is nearing the end of its life, we can alert the scientific community and be ready to watch as a star experiences its final moments.
Observatories such as the European Southern Observatory and the Zwicky Transient Facility are currently used to identify the signs that indicate a star is nearing the end of its life.
The discovery of SN2023fyq, which provided astronomers with a rare opportunity to observe the first light from a supernova shock breakout, offers insights into the conditions leading up to these cosmic events.
