Summary

Story summary

Astronomers observed unusual brightness fluctuations from Gaia20ehk, a star about 11,000 light-years away, indicating debris blocked its light.
Researchers conclude the debris likely resulted from a collision between two planets.
The debris was hot and glowing.
The collision may form a new moon system around Gaia20ehk.
Future telescopes such as the Simonyi Survey Telescope could identify more planetary impacts and advance understanding of planetary formation and the conditions for life.
