# First sugar molecule found in space hints at life's origins

Astronomers have detected the first "true sugar" molecule, glycolaldehyde, in a region of space where stars and planets form. This simple sugar is a key building block for RNA, a molecule essential for life. The discovery supports the idea that life's molecular precursors can form in interstellar space and be delivered to planets.
