"Betelgeuse's Fiery Supernova: Unveiling the Eerie 'Space Ghost' in the Night Sky"

A recent study suggests that the red supergiant star Betelgeuse could potentially explode into a supernova in the coming decades, but one scientist proposes that it may have already happened due to its distance from Earth. The exact distance of Betelgeuse has been debated, with estimates ranging from 450 to 550 light years away. If Betelgeuse exploded in the past 499 years, the light from the event has not yet reached Earth, making it impossible to know if it has already blown up. However, if it exploded in 1600 AD, we would only find out in the year 2100. Regardless, the supernova is not expected to have any negative impact on Earth.
