Betelgeuse, a boiling star the size of the orbit of Jupiter:

I wish I could post video over here, because this new animation of Betelgeuse is just spectacular. There is a seething cauldron of red-hot gas in the shoulder of Orion.
(Blade Runner almost got it right.)

Video & info at link:

“…the surface of Betelgeuse is a vibrant world, governed by a physical process called convection. We can observe convection in our daily life when we boil water, but in Betelgeuse, this process is much more violent: The boiling bubbles can be as large as Earth’s orbit around the Sun, covering a large fraction of Betelgeuse’s surface. They rise and fall at a speed of up to 30 km/s, faster than any crewed spacecraft.”https://www.mpa-garching.mpg.de/1094283/hl202403
