First sugar detected in interstellar space reshapes origin-of-life theories - MSN

A four-carbon sugar found 26,700 light years away hints that life's chemical building blocks may be assembled in deep space, not just on young planets.

Theory Briefing

  • Erythrulose, a four-carbon sugar, was detected inside a giant molecular cloud 26,700 light years from Earth — the first sugar ever found in interstellar space.
  • The discovery challenges the assumption that complex organic molecules needed for life only form on planetary surfaces or in their atmospheres.
  • Finding a sugar this far out suggests the raw chemistry of life may be seeded across the galaxy long before any planet forms.
  • Erythrulose is biologically relevant on Earth, raising the question of whether its cosmic presence is coincidence or a universal chemical pathway.
