Glycine found in space

Normal glycine, a basic amino acid that many computer scientists adopt to increase productivity and relieve nervous tension, was found on Comet Wild 2 as part of the distributed project Stardust @ Home.

The project Stardust @ Home was launched on February 7, 1999, when the small scientific ship Stardust (“Star dust”) was launched into space. His task was to penetrate the tail of Comet Wild 2 and collect samples of matter - the so-called interstellar dust, which is the oldest material that remained unchanged since the formation of the Solar System 4.5 billion years ago.

On January 15, 2006, after seven years of travel, the spacecraft returned and dropped a capsule with stellar dust samples to Earth. Scientists carefully removed the airgel collector the size of a tennis racket, placed it in a microscope and carefully scanned the entire surface area of ​​1000 square meters. See. It turned out almost a million photographs that needed to be carefully reviewed for the presence of a foreign substance. This is exactly what the participants of the Stardust @ Home project have been doing for the last three years.

The experiment was extremely successful. First, it was possible to find many particles of star dust. Secondly, traces of glycine were found on these samples. The substance is clearly of unearthly origin, because it contains much more ¹³ C isotopes than in terrestrial glycine.

Thus, scientists have obtained convincing evidence that comets really transfer life from one galaxy to another. They (through meteors or meteorites) brought basic amino acids to the Earth a couple of billions of years ago. It turns out that in other galaxies, life could also originate from the same basic bricks.

That is, the inhabitants of other planets can be humanoids, similar to us both externally, and in metabolism, and in physiology. If there is intelligent life throughout the cosmos, then it has common roots. At the very least, aliens should definitely be in the visible part of the spectrum.
