To your eye, Betelgeuse is the bright "shoulder" star in Orion. A new simulation shows what it would look like if you could get up close: an enormous, boiling cauldron of gas.
If Betelgeuse were placed where the Sun is, Earth's orbit (blue circle) would be deep inside. That's how big it is!

Betelgeuse is a well-known red supergiant star in the constellation Orion. Recently it has gained a lot of attention, not only because variations in its brightness led to speculations that an explosion might be imminent, but also because observations indicated that it’s rotating much faster than expected. This latter interpretation is now put into question by an international team led by astronomers at Max Planck Institute for Astrophysics, who propose that Betelgeuse’s boiling surface can be mistaken for rotation even in the most advanced telescopes. Other astronomers are actively analyzing new observational data to test such hypotheses.
