Meteorite found in Sahara desert may be 1st evidence of lost solar system world

AI-summarised brief · reviewed before publication

A rare meteorite, known as Northwest Africa (NWA) 12774, has been discovered in the Sahara Desert. The meteorite, classified as an angrite, is a type of rock that formed alongside the young sun more than 4.5 billion years ago. Scientists have found that the meteorite preserves a unique chemical signature that suggests the early solar system's planets developed differently. The meteorite's composition and structure indicate that it originated from a large, lost world that may have rivaled the moon in size.

💡 Why It Matters

  • · This discovery provides a window into the early solar system's formation and evolution, revealing a previously unknown pathway for planetary development.
  • · The existence of a large, lost world challenges current understanding of the solar system's history and raises questions about the fate of other potentially similar worlds that may have been destroyed in violent collisions.
