The article presents scientific findings without apparent bias, focusing on the research outcomes.

For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, the team found that the giant star's inner atmosphere has become increasingly uneven and asymmetric, in a way that could be connected to a far smaller companion star.
