Three images in a row are labelled, from left to right, ‘2023-07-18,’ ‘2023-07-27,’ and ‘2023-08-02’, respectively. Each image shows a blurry, yellow sphere with dark and light patches, against a grainy, brown background. The patches move and change between each image. In the bottom left of the first image, the outline of a circle slightly smaller than the yellow sphere is labelled, ‘Earth’s orbit’.

1/ It's amazing that we can see details on the surface of some stars, but watching them move is even cooler 🤩
Using ALMA, astronomers have followed the motion of gas bubbles on the red giant star R Doradus over the course of a month. The bubbles are huge, about 75 times bigger than the Sun!
