# Webb observes young star systems with Moon-forming style impacts

New observations from the James Webb Space Telescope have characterised violent debris disks matching conditions when Earth's Moon formed.

NASA's James Webb Space Telescope has examined a class of young stellar systems showing violent upheavals similar to the impact that created Earth's Moon.[^1]

Researchers confirmed these extreme debris disks share three consistent properties: smaller dust grains than those in protoplanetary or classic debris disks, a high concentration of warm dust, and irregular brightness variations.[^2] The work was published in The Astrophysical Journal Letters.[^3]

These unusual disks were first noted near the end of the mission of the retired Spitzer Space Telescope, before Webb was brought in for detailed observation.[^4]
