    What the red star needed was a charger. But it bought the wrong USB charger.

    Maybe something is in the way... some kind of cosmic dust?

    Betelgeuse's Wild Surface Seems to Be Baffling Our Telescopes

    There's something peculiar about dying star Betelgeuse.

    Yeah, there was the whole sneeze thing. That's been pretty much resolved for now. But before the Great Dimming Debacle of 2019, scientists spotted something even more peculiar about the giant star. Radio measurements of its changing light suggested it was rotating at 5 kilometers (3.1 miles) per second.

    The big problem with that is that stars of Betelgeuse's vintage should, theoretically, have a maximum rotation speed at least two orders of magnitude lower. So, astronomers wonder, what the heck gives?

    Hot material bubbles up, cools, and falls down. This happens on the Sun, too, with convection cells the size of Texas, but the process is much more violent on Betelgeuse, with convection cells that can be as large as Earth's orbit around the Sun (Betelgeuse is large enough to extend as far as Jupiter's orbit).
