Unusually fast-moving gas clouds near a nearby galaxy suggest they may have come from outside the galaxy. Scientists have ...

Researchers discover high-velocity clouds in the nearby spiral galaxy M83. These clouds are moving at speeds significantly ...

Galaxies have an overall internal motion called disk velocity. It’s how gas, dust, and stars move around the galactic center.

NASA’s Hubble and Webb telescopes observe explosive star formation in the Small Magellanic Cloud's NGC 460 and NGC 456 clusters.

A new result from the molecular gas survey in the Southern Pinwheel Galaxy M83 using the Atacama Large Millimeter/submillimeter Array (ALMA) Telescope reveals a discovery of 10 high-velocity clouds ...

Researchers have discovered cold hydrogen clouds within superheated Fermi bubbles at the Milky Way's center, challenging ...

A quiet, glowing gas cloud has been hiding in plain sight not far from Earth. For decades, astronomers have predicted that some of the galaxy’s molecular gas — the fuel for star birth — might be ...

Back in 2010, scientists spotted something shocking: a pair of gigantic, glowing lobes of gas bursting from the Milky Way’s ...
