Locations of HVCs. Multiple images like this, made by radioastronomy, allowed researchers to measure the velocities of small ...

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

A new result from the molecular gas survey in the Southern Pinwheel Galaxy M83 using the Atacama Large ...

Astronomers using the Green Bank Telescope spotted surprisingly cold, dense hydrogen clouds embedded inside the Milky Way’s ...

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.

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 ...

Galaxies shine in a rainbow of emissions from gas, dust, and stars. Each of these building blocks emits light at specific ...

The researchers observed the Sculptor Galaxy for over 50 hours with the Multi Unit Spectroscopic Explorer (MUSE) instrument on the VLT to create the detailed map. They then stitched together over 100 ...
