These images, taken with ESO’s Very Large Telescope (VLT), show a planetary system forming around the young star WISPIT 2. The star is surrounded by a disk of gas and dust – the raw material from which planets form and grow. In 2025, a team of astronomers detected a young planet, WISPIT 2b, carving a gap in the disk around the star. Now, the same team has confirmed the existence of a second planet, WISPIT 2c, orbiting the star more closely, as shown in the enlarged image. Both planets are gas giants, similar to Jupiter. WISPIT 2b is almost five times more massive than Jupiter and orbits the star at a distance that is sixty times greater than the distance between Earth and the Sun. WISPIT 2c is twice as massive as WISPIT 2b and orbits the star at a distance that is four times smaller. The images were obtained with the SPHERE instrument on the VLT. The instrument corrects for the blurring caused by atmospheric turbulence, and also blocks the light from the central star, revealing the disk and its surrounding planets in great detail. Another instrument, GRAVITY+ on the VLT interferometer, was also used in the discovery and helped confirm that the observed object is indeed a planet. Credit: ESO / C.

A solar system in the making? Two planets observed forming in a disk around a young star

Observations by the European Southern Observatory have revealed two gas giants within a disk of dust and gas around a young star, in a system that may resemble the early solar system.
