Discovered the first molecule in the Universe
Source:Have you ever Thought ever about how and when the Universe appeared molecules? After the Big Bang nearly 14 billion years ago as a result of chemical reactions were molecules that played a crucial role in the formation of everything we know. But what was this molecule has remained a mystery. Fortunately, until recently,: recently, scientists have discovered the first molecule of the Universe. The discovery was made by an international team of astrophysicists using the world's largest stratospheric Observatory Stratospheric Observatory for Infrared Astronomy (SOFIA) is placed on the aircraft the 747SP that can fly above the lower atmosphere. It is noteworthy that SOFIA has a spectrometer of high resolution. This tool allowed to detect the molecule. It turned out that the first molecule in the Universe appeared approximately 100,000 years after the Big Bang. It happened in the 3000 light years from Earth, in the planetary nebula NGC 702. Theoretically, this molecule should exist – we are talking about helium hydride ion (HeH+), which was formed from atoms of helium and hydrogen. Both elements are the most abundant in the Universe, and first of all it's hydrogen and only secondarily helium. Scientists have searched for her in 1925.
Molecular chemistry in space
Lack of definitive evidence for the existence of HeH+ in interstellar space has long been a dilemma for astronomy. Astronomicheskie models of the late 1970-ies showed the possibility to detect such objects. This has led scientists to believe that the helium hydride ion can exist in a chaotic planetary nebula ejected by a star similar to the Sun, which are at the last stage of its evolution – before you collapse in a supernova.

Planetary nebula NGC 702 located in the direction of the constellation Cygnus. In it are the remains of dead stars surrounded by a dense shell. Researchers believe that this primary gas neutral helium is interacted with ions of hydrogen, forming the first in the history of the Universe chemical bond, creating the first molecule. To find the elusive molecule, scientists have searched for the characteristic frequency of light that it emits, in particular a spectral line in the far infrared range, which is normally blocked by earth's atmosphere. But a spectrometer for far infrared on Board «Sofia» allowed them for the first time to detect this signature in a planetary nebula called NGC 7027 (pictured above), report researchers today in the journal Nature. The result shows that this unlikely molecule, including non-reactive helium, can be created in space. When the cornerstone confirmed, it seems that the evolution of the next 13 billion years the chemistry stands on firmer ground.

According to CNN News, the discovery of the helium hydride ion is a perfect demonstration of the tendency of nature to form molecules. So says David Neufeld, a co-author of the study and Professor in the Department of physics and astronomy at Johns Hopkins University. More exciting news about our Universe you will find.
the very first molecule in the Universe was found after 85 years after the discovery in the laboratory
Despite the unpromising ingredients that are available, a mixture of hydrogen with an inactive noble gas helium and the harsh environment at thousands of degrees Celsius, formed a fragile molecule. It is noteworthy that this phenomenon can be seen not only astronomers, but also understood with the help of the developed theoretical models.
Researchers believe that the new discovery, which is published confirms a key part of a basic understanding of simple chemistry in the Universe immediately after its birth. According to scientists, this work confirms a key part of a basic understanding of simple chemistry in the early Universe and to explain how over billions of years it evolved into today's complex chemistry.
the very first molecule in the Universe originated in a nebula close to our planet
