It's important to note that these molecules were found in interstellar clouds, which are vast regions of gas and dust spread throughout the galaxy. These clouds are not at a specific fixed distance from Earth.

However, some of the clouds where glycolaldehyde has been detected are relatively close to us, such as the Sagittarius B2 cloud, which is about 26,000 light-years away.

Other discoveries have been made in more distant regions of the galaxy.

Therefore, there isn't one single answer to how far away the sugar found in space is from Earth. It depends on which specific interstellar cloud is being discussed.
