Very fascinating.

I found the text accompanying the youtube submission quite helpful to understand the simulation:

The intensity movies show the star approximately as it might appear to the human eye (In detail: The emergent bolometric surface intensity is color coded with the standard "red-heat" table, to get a color representation adequate for a red supergiant.). The "boiling" surface of the star shows irregular hot (white or yellow) and "cool" (red or dark-red) areas. They change their intensity and shape on time-scales of months.

Simulation of what the surface of the star Betelgeuse might look like to the human eye

Uh oh.

Betelgeuse size
Betelgeuse will explode someday

You guys have done it now. :(

I gather any planets Betelgeuse might have had are long gone by now.

Absolutely mesmerizing.

And this thing is a star?...I'm moving to Mars.

So, is this how the star would look to the human eye if I saw it through Earth's atmosphere or if I saw it in space? I would presume that seeing a star through the atmosphere will change the way it looks to the human eye.

Without context , I would have believed it to be a visualization screen in winamp. Thanks for sharing.

Kinda looks like one of those prolapse videos you see on Efukt
