Story summary

Astronomers at The University of Western Australia report a 185,000-light-year gas bridge linking the dwarf galaxies NGC 4532 and DDO 137, about 53 million light-years away.
The discovery, published in Monthly Notices of the Royal Astronomical Society, notes tidal forces and ram pressure from the Virgo cluster stripping gas over billions of years.
The bridge's gas is crucial for star formation and shapes galaxy dynamics in dense environments.
