Scientists have discovered a massive, long-lasting starspot on the star TOI-3884, covering about 7% of its surface and persisting for at least seven years, using transit observations of its Neptune-like planet, TOI-3884 b, which exhibits unusual transit signatures due to the starspot's influence.
New research suggests that Betelgeuse's apparent fast rotation may be an illusion caused by its turbulent, convective surface rather than actual rapid rotation. Observations from the ALMA telescope, which previously indicated high rotation speeds, may actually be detecting the effects of the star's violent convection. Further high-resolution observations are needed to clarify Betelgeuse's true rotation speed, which could provide insights into its evolution and behavior as a red supergiant star.
