Astronomers have made a discovery about the star Betelgeuse, which is expected to explode at some point. The findings suggest that Betelgeuse may have a companion star that is leaving a detectable wake, although some reports also mention a different star that was spotted by the JWST telescope. The nature and implications of the discovery are still somewhat unclear, with various outlets describing it as a breakthrough related to a star that may be on the verge of exploding.
