Discovery of a huge molecular cloud near the solar system

According to RCO News AgencyMolecular clouds are mainly composed of molecular hydrogen and other molecules, along with cosmic dust. These dense clouds, often covering hundreds of light -years away, are the birthplace of stars and planetary poems, and their temperature is usually between 1 and 2 Kelvin and their density between hundreds and millions of molecules per cubic centimeter.

“Molecular clouds” are significantly more dense than the “Interstellar Medium”. The gravitational force ultimately collapsing the dense areas within these clouds and forms “Protostars” that become new star system.

Scientists, led by Blakesley Burkhart of the University of Rutgers, discovered the EOS molecular cloud. This huge hydrogen molecular cloud is among the largest and closest structures to our solar system.

The discovery is highlighted due to the identification of the first “molecular cloud” using the spread of ultraviolet light instead of traditional methods. The name “EOS” is derived from the name of the Greek goddess of dawn and reflects a significant improvement in observation techniques. The discovery also reveals new approaches to the study of molecular structures in space.

The team’s new approach allowed them to identify the fluorescence radiation of this “molecular cloud”, which is the result of the brilliance of hydrogen molecules, directly without the use of traditional observation methods. Despite its proximity to our solar system, “EOS” creates no threat to the earth.

This “molecular cloud” provides a valuable opportunity for researchers to study the properties of the “interdesist environment” closely. This cloud is an important raw material for the formation of future stars and offers unique insights about these processes because of the availability of accurate observations.

This crescent molecular cloud is about 5 light -years at the edge of the Local Bubble area and covers approximately 2 moons in the sky with a crime of 2 times that of our sun. Scientists predict that the cloud will evaporate in the next 5 million years and was observed by the UV spectrometer on the STSAT-1 Korean satellite.

This discovery reveals the value of using new observation techniques, as the molecular hydrogen cloud is hidden because it does not maintain mainly carbon monoxide molecules and lacks chemical properties.

According to Blixley Burkehart, a senior researcher at the study, the hydrogen atoms in EOS have traveled about 1.5 billion years from Big Bang to the formation of the cloud near the Solar System.

A member of the team, Tavisha Dharmavardena, was surprised by the direct observation of molecular hydrogen that was previously difficult to identify.

It is noteworthy that the Burkehart team has identified some of the farthest molecular hydrogen using the James Web Space Telescope (JWST). They have discovered the closest and farthest hydrogen molecules from our sun.

The finding is published in the journal Nature Astronomy.
