NASA’s Webb Provides Crash Course on Planet-Shattering Collisions
Astronomers using the James Webb Space Telescope have studied rare 'extreme debris disks' around young stars to understand violent planetary collisions. The findings suggest that such chaotic events, similar to the one that formed Earth's moon, are less common than previously theorized.
Why it matters
Understanding the formation and evolution of planetary systems provides context for the history of our own solar system and the potential for life elsewhere.
