New Images Reveal Young Solar Systems Filled With Secret Planets
New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building bodies. The structures often resemble our asteroid and Kuiper belts, hinting at unseen giant planets sculpting the dust. By comparing 51 systems, astronomers found clear trends linking star mass to disk mass and size. These images lay [...]
Gallery of young debris disks around distant stars
3.12.2025 - SPHERE-s images of dust around distant stars provide a glimpse of asteroids and comets in other solar systems. Traces of comets and asteroids in distant solar systems: In young planetary systems, mutual collisions between asteroids or comets generate large amounts of dust, forming a 'debris disk'.
An international scientific team comprising several French teams, including astronomers from the Institute of Planetology and Dastrophysics of Grenoble (IPAG – UGA/CNRS) conducted the largest ever study on debris discs using the Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Chile, revealing new knowledge on the formation and evolution of planetary systems. The debris discs are comparable to the d-asteroid belt or Kuipe…
