The Milky Way’s deadly cosmic cocktail smells like rum and tastes like raspberries

Close to the centre of our galaxy, there exists an immense molecular cloud known as Sagittarius B2. This has been a subject of interest among scientists due to its peculiar composition, which includes chemicals capable of giving it the aroma of rum and the taste of raspberries. The presence of ethyl formate, which produces the raspberry-like flavour and the sweet smell of rum, was discovered in this cloud. Sagittarius B2 is one of the biggest clouds of dust and gas found in space, situated near the centre of the galaxy. It is believed that this strange region could provide clues on how complex organic compounds develop in interstellar space.

What is Sagittarius B2 in the Milky Way and why is it fascinating astronomers

Sagittarius B2 is one of the largest molecular clouds and is located about 390 light-years away from the galactic centre of the Milky Way galaxy. The cloud is close to Sagittarius A*, which is a super massive black hole situated at the centre of the Milky Way galaxy. The cloud is very large, spanning a size of about 150 light-years and consists of gas, dust particles and molecules.

For years now, scientists have studied Sagittarius B2 as a sort of natural chemistry lab in space. The research team at the Max Planck Institute for Radio Astronomy found that this cloud has numerous forms of carbon compounds, ranging from alcohol to acids, as well as those that are related to biological chemistry.

The molecule of interest that gained international attention is ethyl formate, which imparts raspberries their characteristic flavour and gives rum its odour. The discovery of ethyl formate was accomplished through the use of the IRAM 30-meter radio telescope in Spain.

Why the cosmic cloud smells like rum and tastes like raspberries

Even though nobody can smell or taste Sagittarius B2, researchers have used examples of terrestrial odours to describe the composition of the interstellar cloud. Ethyl formate is a type of organic compound called an ester, which usually has fruity flavours and fragrances.

According to the Australian Academy of Sciences, the discovery stated:
“The detection of ethyl formate in an interstellar cloud is like detecting a molecule that tastes like raspberry and smells like rum.”

However, there is something more dangerous in the Sagittarius B2 than just ethyl formate. Methanol, for instance, is one of the hazardous substances existing in the cloud. Additionally, the area near the centre of our galaxy features extreme temperature and radiation levels.

Based on estimations, the amount of ethyl formate in the cloud would allow producing tons of so-called “space rum.”

How interstellar chemistry could explain the origins of life

Organic molecules found in the Sagittarius B2 are significant because they confirm that there could be complex chemistry occurring naturally in outer space. Experts claim that these molecules could be involved in processes of stellar evolution and in bringing the necessary components of life.

Based on information from the European Southern Observatory, another molecule known as n-propyl cyanide was found in this same cloud. The presence of such complex molecules indicates that even more complicated molecules can be formed in outer space by natural chemical processes.

This scientific research has a huge impact on modern astrochemistry – the branch of science which studies the behaviour of molecules in space environments. In addition, future discoveries concerning these processes might be made using new radio telescopes and deep-space expeditions.

Why the Milky Way’s “cosmic cocktail” still fascinates scientists

While the thought of an immense cloud giving off the smell of rum and the taste of raspberries would naturally spark imagination, there is much more to this object for researchers. Indeed, Sagittarius B2 is considered one of the best illustrations of natural chemical processes taking place in the depths of outer space.

For scientists, this object provides hints concerning the formation of planets and the chemical evolution of galaxies. For everyone else, this object remains an example of how surprising and unpredictable our Universe is.
