James Webb Telescope Uncovers New Evidence of Cosmic Collisions—and One of Them May Have Created Our Moon
Webb identified silica-rich and silica-poor disks, with about one-third showing signs of high-velocity impacts between Mars-sized bodies, researchers said.

NASA’s Webb Telescope uncovers clues to moon-forming collisions around distant stars
NASA’s James Webb Space Telescope has found new clues that could help scientists investigate the mechanics of satellite-forming impacts in exoplanetary systems displaying signs of similar...
They examined rare debris disks that can form around only 1 percent of young stars. The Sun may have once been among them. The post Hungarian researchers observed traces of planetary collisions with the James Webb Space Telescope first appeared on 24.hu.
Massive collisions shape the formation of rocky planets, but their debris can usually only be observed indirectly. Spectra of 21 extreme debris disks now show that the mineralogy of their dust provides indications of the size and energy of such impacts. Systems with pronounced silicon dioxide traces indicate particularly energetic collisions of large planetary bodies. Greenbelt (U.S.A.). Young planetary systems can [...] The article Webb telesco…
NASA's Webb Finds Alien Worlds Colliding Hard Enough To Vaporize Rock
Observations from NASA's Webb telescope have revealed detailed chemical fingerprints from catastrophic, planet-shattering collisions in other solar systems, which in turn offer a peek into how worlds like Earth might have formed and evolved. Published in The Astrophysical Journal, research led by Dr. Kate Su of the Space Science Institute
