Astronomers led by Anne-Marie Lagrange, a CNRS researcher at the Institut de Planétologie et d’Astrophysique de Grenoble (CNRS/Université Grenoble Alpes) has discovered a second giant planet in orbit around beta Pictoris, a star that is relatively young et just 23 million years old and close (63.4 light years away), and surrounded by a disk of dust. The discovery is detailed in Nature Astronomy.

The team includes researchers from other French laboratories – Lagrange laboratory (CNRS/Observatoire de la Côte d’Azur/Université Côte d’Azur), Laboratoire d’études spatiales et d’instrumentation en astrophysique (CNRS/Observatoire de Paris – PSL/Sorbonne Université/Université de Paris), Institut d’astrophysique de Paris (CNRS/Sorbonne Université) – as well as researchers from the Max Planck Institute for Astronomy (Germany), the South African Astronomical Observatory, the University of Warwick (UK), Leiden Observatory (the Netherlands), European Southern Observatory, Universidad de Chile and Universidad de Valparaiso (Chile).
