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

Deep within the Milky Way’s core, researchers have uncovered cold gas clouds racing through a superheated galactic wind.

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

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

New research suggests that the mysterious Fermi and eROSITA bubbles originated form a single 100,000-year-long explosion 2.6 million years ago ...

The Fermi Bubbles are two enormous orbs of gas and cosmic rays that tower over the Milky Way, covering a region roughly as large as the galaxy itself. These giant space bubbles may be fueled by a ...

The Fermi bubbles, shown in purple in this image created from gamma-ray observations, are giant balloons of plasma that extend away from the Milky Way’s starry disk (blue). Fermi LAT ...

Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds – or Fermi bubbles – at the Milky Way’s center. The finding challenges current models of Fermi ...

There are swooping tendrils of energy visible only in radio wavelengths, hourglass-shaped scars of X-ray light and — towering over it all — the mysterious Fermi Bubbles.

Although uncertain of the bubbles’ origins, scientists have observed a “cocoon” substructure in the southern Fermi bubble producing gamma rays — could this be evidence of a weakly ...
