    — Keith Cooper, Space.com, 22 Aug. 2025
  • The Apollo 14 and 15 missions ventured near Mare Imbrium, one of the largest craters in the solar system, and collected ejecta, or material blasted out by the initial impact and spread across much of the lunar near side.
    — Ashley Strickland, CNN Money, 21 Feb. 2026
  • In more mature planetary nebulae — or even in preplanetary nebulae that are closer to the end of their preplanetary stage (with hotter stars powering them) — the ejection process has been muddied by a thousand years or more of earlier ejecta being overtaken by faster-moving, more recent ejecta.
    — Big Think, 11 Feb. 2026
