The molecule, called glycolaldehyde, was spotted in a large star-forming area of space around 26,000 light-years from Earth in the less-chaotic outer regions of the Milky Way. This suggests the sugar could be common across the universe, which is good news for extraterrestrial-life seekers.

"This is an important discovery as it is the first time glycolaldehyde, a basic sugar, has been detected towards a star-forming region where planets that could potentially harbor life may exist," Serena Viti of University College London said in a press release.

"The discovery of an organic sugar molecule in a star forming region of space is very exciting and will provide incredibly useful information in our search for alien life,” said Keith Mason, chief executive of the England’s Science and Technology Facilities Council.
