Planets around other stars, also called exoplanets, are seen everywhere! In the last 25 years, thousands of exoplanets have been found throughout the Milky Way. How do we find these planets? What are the chances of discovering life there? And if they are so common, why is it that we still don’t know how they are formed? With the ALMA telescope we can now finally zoom into the birth cradles of planets: dusty disks around young stars. The spectacular images have given us new insights, but also raised many more questions on the process of planet formation.
