Using the IRAM radio dish array in France, a team of European astronomers has detected glycolaldehyde--a simple sugar that makes up ribose, one of the constituents of RNA--within the core of what appears to be a coalescing disk of dust and gas in a star-forming region called G31.41+0.31, about 26,000 light-years away.

The reaction is so facile that it would be surprising if it didn't occur given the presence of these molecules (cyanimide, cyanoacetylene, glycolaldehyde, glyceraldehyde, and inorganic phosphate).
