Story summary

An international team led by the University of Oxford found a 5.5-million-light-year chain of hydrogen-rich galaxies rotating in a cosmic filament about 140 million light-years from Earth.
The galaxies rotate with the filament and show that filaments influence rotation and evolution.
The findings appeared in Monthly Notices of the Royal Astronomical Society with MeerKAT data from South Africa.
The study enhances understanding of galaxy formation and cosmic gas flow.
