Two articles to be published in the journal “Astronomy & Astrophysics” describe the discovery and characterization of a planet still in its formation phase orbiting the young star PDS 70. Two teams of astronomers used the SPHERE instrument installed on ESO’s VLT to obtain for the first time images of a planet while it’s forming in what is still more or less a disk of gas and dust around the star. Called PDS 70b, the planet is a gas giant that could be larger than expected for its age.
