Bilder des Sterns R Doradus wurden im Juli und August 2023 mit dem Atacama Large Millimeter/submillimeter Array (ALMA) aufgenommen. Sie zeigen riesige, heiße Gasblasen, 75-mal so groß wie die Sonne, die auf der Oberfläche erscheinen und wieder ins Innere des Sterns sinken

“…bubbles of gas, 75 times the size of the Sun…”
That is just mind-boggling.
That description doesn’t paint a good picture. The image just looks like lens aberration. What’s the artist representation?
For reference, R Doradus
* is 178 light years away,
* has a mass equal to or slightly *less* than the Sun,
* takes 57 years to rotate on its axis,
* has a diameter of ~410 million km,
* would fill the inner solar system out to around the orbit of Mars.
Makes me curious if a common shape of a star is more of a non-spherical blob rather than the spherical shape that we tend to think of. Probably depends on the state of the lifecycle of the star in question.
We should point jwst at this thing
