Betelgeuse is haunted by a cosmic poltergeist tormenting the doomed star's atmosphere

Recent radio observations reveal that Betelgeuse’s atmosphere is demonstrating signs of recovery following its significant dimming event in late summer and early autumn of 2021. Astronomers utilizing Very Large Array (VLA) telescopes have captured detailed radio images indicating an ongoing process of atmospheric replenishment. Simultaneously, a smaller companion star is actively interacting with Betelgeuse, penetrating its outermost layers. This interaction appears to be contributing to the observed changes within the supergiant's gaseous envelope. Scientists are continuing to monitor these dynamic processes at both optical and radio wavelengths to fully understand the complex behavior of this iconic variable star.
