Ever thought what the middle of the galaxy smells like? Dependent on your fondness, the answer could be raspberries or rum. As dubious as these sounds, the detection was made when astrophysicists from the Max Plank Institute used the IRAM radio telescope in Spain to observe Sagittarius B2, a dirt cloud close to the center of the galaxy. The publication was made at the time in Astrophysics and has since been established with readings of related dust clouds. Amongst the chemicals for which signals were originate was ethyl formate (C3H6O2), the governing flavor is raspberries, in addition to a significant one in rum.

Now before supporters start getting too carried away with ideas for huge drunken berry picking space journeys there are a few things that are essential to be pointed out. The Institute's Arnaud Belloche spoke to The Guardian “Ethyl formate does happen to give raspberries their flavor, but there are many other molecules that are needed to make space raspberries,". The thickness is also far too thin to be beneficial, and there is that annoying absence of sufficient oxygen to breathe.
Furthermore, the smell is barely pure. Belloche found nearly 4000 distinct signals in Sagittarius B. Belloche said at the time "So far we have identified around 50 molecules in our survey, and two of those had not been seen before," but since then development has been prepared on founding the source of some of these. The discovery assists as a reminder that a lot of the chemicals we know as a creation of living things can be formed in other ways, counting through the effect of ultraviolet light on other molecules, as in this event. Alcohols, counting ethanol, turn up quite regularly in space. On Earth, ethyl formate is usually formed when ethanol reacts with formic acid. The goal for astrophysicists like Belloche is to find amino acids, the building masses of life. As glycine, the pretentious amino acid, is no bigger than ethyl formate, the discovery improved their confidence. Statements for the find of glycine have been made earlier, but have appealed little backing.
Belloche says "The difficulty in searching for complex molecules is that the best astronomical sources contain so many different molecules that their 'fingerprints' overlap and are difficult to disentangle,"
