Astronomers have discovered two giant planets forming around the young star WISPIT 2, offering a rare real-time view of planetary formation. Observations from the European Southern Observatory confirmed the second planet within the system’s gas and dust disc, whose structure resembles an early version of our Solar System. According to Chloe Lawlor, this system provides one of the clearest insights yet into how planetary systems like ours may have formed.

Twin Planet Formation Seen in Young Star System

Christian Ginski explains that WISPIT 2 serves as a valuable natural laboratory for studying the formation of entire planetary systems, not just individual planets. Observations of such systems help scientists understand how young planetary systems evolve into mature ones like our Solar System.

Rare System Shows Planets Forming

WISPIT 2 is only the second known system—after PDS 70—where astronomers have directly observed two planets forming around the same star [1]. Its unusually large disc, marked by di stinct rings and gaps, suggests that additional planets may still be forming and could be discovered in the future, as noted by Chloe Lawlor.

Two Giant Planets Confirmed Around WISPIT 2

WISPIT 2 hosts two confirmed forming planets. The first, WISPIT 2b, is about five times the mass of Jupiter and orbits far from its star. A second planet, WISPIT 2c, was later confirmed using observations from the European Southern Observatory and orbits much closer, with roughly twice the mass of WISPIT 2b. As noted by Richelle van Capelleveen, these discoveries highlight the power of modern instruments. Both planets are gas giants, similar to those in our Solar System.

Advanced ESO Tools Drive Discovery

To confirm WISPIT 2c, researchers first captured direct images using the SPHERE instrument on the European Southern Observatory’s Very Large Telescope, and then verified its planetary nature with the upgraded GRAVITY+ instrument on the VLTI [1]. According to Guillaume Bourdarot, the recent enhancements to GRAVITY+ were essential for clearly detecting a planet located so close to its host star.

Possible Third Planet in Formation

Astronomers have detected an additional, smaller gap in the disc surrounding WISPIT 2, suggesting the possible formation of a third planet. Chloe Lawlor proposes that this planet could be similar in mass to Saturn due to the gap’s size. Future observations, potentially using the European Southern Observatory Extremely Large Telescope, may allow scientists to directly image this candidate planet, as noted by Christian Ginski.
