Rude as it may seem, one of our galaxy’s most massive stars is belching its innards far into space. New telescopic observations released 29 July reveal gigantic gas bubbles erupting from Betelgeuse, the behemoth that lies 640 light-years away and sits on the constellation Orion’s right shoulder. The observations solve the mystery of how such a gravitationally powerful star could be ejecting material far away from its surface. As the gas bubbles burst and collapse, they slingshot parts of themselves out into space. Astronomers still don’t know how the bubbles form, but they do know one thing: The Betelgeuse system is no place for a party.
