Measuring approximately 3,900 light-years long, this structure composed primarily of hydrogen gas was identified as Maggie and could reveal information about the cycle of matter in stars, the MPIA reported in a statement. “Analysis of the measurements suggests that atomic gas in this line converges locally to form hydrogen molecules. When compressed into large clouds, this is the material from which stars eventually form, “explained the astronomical institute. Hydrogen, the scientists recalled, is the The most widespread substance in the universe and a central ingredient in the formation of stars, however the individual detection of hydrogen gas clouds is a demanding task that complicates the record of star formation in its early phases. This makes the finding of this hydrogen filament involved in the conformation of stars, maintained the MPIA of Germany, whose research was published in the journal Astronomy & amp; Astrophysics.

Astronomers led by researchers at the Max Planck Institute for Astronomy (MPIA) have identified a filament that is one of the longest known structures in the Milky Way, the galaxy that is home to our solar system.

Measuring approximately 3,900 light-years in length, this structure composed primarily of hydrogen gas was identified as Maggie and could reveal information about the cycle of matter in stars, MPIA said in a statement.

“Analysis of the measurements suggests that atomic gas in this line converges locally to form hydrogen molecules. When compressed into large clouds, this is the material from which stars eventually form,” explained the astronomical institute.

Hydrogen, the scientists recalled, is the most widespread substance in the universe and a central ingredient in the formation of stars, however the individual detection of hydrogen gas clouds is a demanding task that complicates the record of star formation in its phases. early.

This makes the finding of this hydrogen filament involved in the formation of stars more significant, said the MPIA of Germany, whose research was published in the journal Astronomy & Astrophysics.

Observations around Maggie allow us to determine the speed of hydrogen, explained one of the researchers, Henrik Beuther.

This speed of hydrogen in the gaseous state is determined mainly by the rotation of the Milky Way’s disk, detailed the German institute.

At 3,900 light-years long, the filament is also about 130 light-years wide, explained Sümeyye Suri, another of the co-authors of the scientific paper.

It is located about 55,000 light years from Earth, at one end of the galaxy, the researchers explained.

“But exactly how the transition from atomic to molecular hydrogen occurs is still largely unknown. That makes the opportunity to study this extraordinarily long filament even more exciting,” the astronomers explained.

One of the researchers, Juan D. Soler, named Maggie the filament in remembrance of the longest river in his native Colombia, the Magdalena, after identifying the first clues of galactic condensation a year ago.
