Betelgeuse, one of the brightest stars in the night sky, has fascinated astronomers and astronomy enthusiasts for generations. Located in the constellation Orion, Betelgeuse is a red supergiant that has reached the final stages of its stellar life. Recently, there has been a lot of talk about the possibility that Betelgeuse could explode into a spectacular supernova, visible even from Earth. This event would represent one of the most impressive astronomical phenomena ever observed.

Because the star Betelgeuse is exploding

Betelgeuse is one red supergiant, an advanced stage in the life of a massive star. High-mass stars like Betelgeuse quickly exhaust their nuclear fuel. Currently, Betelgeuse is burning helium in its core, a process that leads to the production of heavier elements up to iron. When iron accumulates in the core, the star is no longer able to produce energy through nuclear fusion. This causes a catastrophic collapse of the core under its own gravity.

During the collapse of the core, temperatures and pressures increase dramatically, leading to the formation of neutrons and the emission of large quantities of neutrinos. These neutrinos quickly escape from the star, followed by a shock wave that propagates through the star’s outer layers, causing the supernova explosion.

Betelgeuse has shown signs of variability in its brightness, a behavior that has raised questions about its evolutionary status. Observations indicate that Betelgeuse may be in the final stage of helium burning or, possibly, beginning carbon burning. The duration of these terminal stages can vary greatly, making it difficult predict exactly when the explosion will occur.

Visible light from Earth: when will it happen

The Betelgeuse explosion as a supernova will be a extraordinary event, visible even during the day and brighter than the full moon. Despite expectations and rumors, this explosion is unlikely to happen in the immediate future. Astronomers estimate that the Betelgeuse explosion could occur in 100,000 to 1,000,000 years, a period that, in astronomical terms, is relatively short, but still very long compared to the human scale.

When the star will explodethe resulting light will be visible for months. The star will increase in brightness until it becomes about 100,000 times brighter than it currently is. This phenomenon will produce light so intense that it will be visible even during the day, casting shadows on the Earth during the night.

The explosion of one supernova it’s not just a visual spectacle that will give breathtaking images, but also an event of great scientific interest. Astronomers use networks of neutrino detectors, such as the Supernova Early Warning System, to monitor and predict such events. Neutrinos emitted during the core collapse arrive at Earth a few hours before visible light, providing early warning to observe the explosion. While Betelgeuse is in the final stages of its life, a supernova explosion is not expected in the near term.

The possibility of being able to observe such a spectacular and scientifically significant event continues to fuel the enthusiasm and interest of astronomers and the public. Even if we will not be able to witness this event, the possibility of simulating and studying what will happen remains a fascinating prospect for science and understanding the universe.
