NASA WISE Telescope Finds Sugar Molecules Around a distant Star

What a sweet cosmic find! Sugar molecules have been found in the gas surrounding a young sun-like star, suggesting that some of the building blocks of life may actually be present even as alien planets are still forming in the system.

The young star, called IRAS 16293-2422, is part of a binary (or two-star) system. It has a similar mass to the sun and is located about 400 light-years away in the constellation of Ophiuchus.

The sugar molecules, known as glycolaldehyde, have previously been detected in interstellar space, but according to the researchers, this is the first time they have been spotted so close to a sun-like star.

In fact, the molecules are about the same distance away from the star as the planet Uranus is from our sun.

"In the disk of gas and dust surrounding this newly formed star, we found glycolaldehyde, which is a simple form of sugar, not much different to the sugar we put in coffee," study lead author Jes Jørgensen, of the Niels Bohr Institute in Denmark, said in a statement.

"This molecule is one of the ingredients in the formation of RNA, which — like DNA, to which it is related — is one of the building blocks of life."
