NASA discovers 'space gum' and sugars 'crucial to life' in asteroid Bennu samples brought to Earth

NASA's analysis of asteroid Bennu samples reveals sugars crucial to life, a nitrogen-rich polymer, and six times more supernova dust than in other astromaterials, aiding origin-of-life studies.

  • Scientists detected ribose, a crucial building block of RNA, and glucose, an energy-rich sugar used by nearly all life on Earth, in samples from asteroid Bennu.
  • The sugars' presence suggests the basic chemical ingredients needed for biology were common in the early solar system.
  • NASA's OSIRIS-REx spacecraft scooped and sealed the pristine Bennu samples directly in space, allowing study of extraterrestrial chemistry uncontaminated by Earth's environment.
