Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.

What is creating these unusual spots?

Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar astrophysics and helps us understand the activity of the Sun, its spot structures and eruptions.
