An article published in the journal “Monthly Notices of the Royal Astronomical Society” reports the detection of a hydrogen filament about three trillion kilometers long in the cosmic neighborhood. A team of researchers led by Yuanming Wang, a doctoral candidate at the Australian University of Sydney, and Dr. Artem Tuntsov of Manly Astrophysics, used the ASKAP radio telescope to discover this ultra-low-temperature gas just 13 light-years from the Earth. In recent years, a lot of gas that forms the baryonic matter considered to be missing has been discovered in filaments that unite different galaxies, in this case it’s inside the Milky Way and in astronomical terms very close.
