ALMA Reveals Long-Lived Hotspots on Betelgeuse's Bubbling Surface

I think there's a 'better' picture of Antares than there is Betelgeuse, but in the best traditions of yak-shaving, I discovered Betelgeuse has an imaged companion:

I know it's 600 ly away but my eyes kept waiting for the images to crisp up anyways, spoiled as they are.

ALMA is a radio telescope, i.e., does not measure visible spectrum / light.

How many are named "Linksys"?
