"Betelgeuse's Baffling Behavior: A Giant Star Defying Astrophysics"

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.

"Deeper Earth Layers Reveal Mountains Bigger Than Everest"

New field research in the mountains of Calabria, Italy, suggests that deeper forces in Earth's mantle, such as convection cells, are responsible for driving some of the uplift we see on the surface, in addition to tectonic plate activity. The study analyzed the ages and chemical composition of rock layers to come up with a history of mountain uplift over 30 million years. The findings challenge the typical way we view mountain building and could teach us more about mountain formation and elevation all across the world.
