Planet birth captured live

A team using multiple telescopes reports the live formation of a giant planet around a young star about 400 light years away.

Planet Birth Captured Live as Gas Giant Emerges in Disk

A team of international astronomers has captured a planet while it forms. The discovery centers on the young star WISPIT 2, roughly 5 million years old and located about 400 light years away. The forming planet, named WISPIT 2b, is a gas giant about five times the size of Jupiter and lies roughly 60 astronomical units from its star. Over two years, observations with the Very Large Telescope and the Large Binocular Telescope revealed a clear gap in the surrounding protoplanetary disk that the planet’s gravity is carving out, signaling active formation. The findings, published in the Astrophysical Journal Letters, provide a rare look at how a planet grows inside its birth disk and how the surrounding material feeds that growth.

This live view of a planet in formation is a milestone for planetary science. It offers a direct test of how gas giants emerge from disks around young stars, a question that has long lived in theory. Scientists will continue to monitor WISPIT 2b to estimate its mass more precisely and to study its atmosphere as it develops, while other telescopes may add new data that refine our understanding of formation timescales and disk dynamics.

This discovery changes how we think about planet formation by offering a real time glimpse into a process that has mostly lived as a model. By watching WISPIT 2b clear a path through the disk, researchers can compare observations with competing theories and adjust them as needed. The result is not just a win for astronomy but a reminder that the universe still has many surprises. The story also highlights how advanced ground based observatories work together to capture rare events, underscoring both the promise and the limits of current technology.
