It is a dead silence, because of ultra-low temperature, ultra-vacuum and strong radiation dissociation, it is difficult to form molecules in interstellar space, not to mention.

It is an organic polymer. However, in 1968, American astronomer Downs and others used a 6-meter radio telescope.

However, ammonia molecules and water molecules were found in B2 nebula of Sagittarius. The following year, another astronomical team in the United States adopted 43 meters.

The radio telescope also found three elements and four atoms in Sagittarius A and Sagittarius B2 nebulae.

Organic molecule-formaldehyde (H2CO). This surprised people. It turns out that there are complex molecules in interstellar space, some of them.

Organic molecules! Many astronomers devote themselves to the study of interstellar molecules. So far, scientists have used shooting.

Electronic telescopes have discovered more than 50 kinds of interstellar molecules, including 6 chemical elements-hydrogen, carbon, oxygen, nitrogen and sulfur.

The most complex molecule is HC9N, which contains 1 1 atoms. Interestingly, 1974 is located in B2 nebula of Sagittarius.

A large number of ethanol molecules (ethanol, that is, alcohol) were found in the center, with a content of 800 billion liters, more than ever on the earth.

People used to brew more wine. People can't help asking, who is the brewer in the sky? These interstellar organic molecules are

How is it formed? Others predict that there are more complex organic molecules in interstellar space, such as amino acids,

But so far, there is no definitive evidence. The discovery of interstellar organic molecules is called the fourth discovery of astronomy in 1960s.

One of the great discoveries. If radio telescopes provide us with indirect evidence of chemical evolution outside the earth,

As we all know, meteorites, messengers from outer space, have brought us direct evidence of the existence of organic matter outside the earth. However, no signs of life have been found in the solar system (except the earth). What is certain is that there must be new life in the universe!
