A 2026 study reveals a rare planetary collision around star Gaia20ehk, 11,000 light-years away, detected via brightness dips and infrared spikes from 2016 to 2021.
In 2026, astronomers detected a rare planetary collision around star Gaia20ehk, 11,000 light-years away in Puppis, using old telescope data.
The star showed unusual brightness dips starting in 2016, with a sharp decline from 2021, likely caused by debris from two planets colliding.
Infrared heat spikes and dust clouds suggest the impact released massive energy, possibly resembling the event that formed Earth’s Moon.
The discovery offers a rare real-time look at planetary formation, helping scientists understand how Earth-like systems may develop.
