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.

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

Those structures — named the Fermi bubbles and eROSITA bubbles after the respective telescopes that discovered them — straddle the Milky Way's center in an enormous hourglass shape, with one ...

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.

Giant bubbles of expanding gas that surround the Milky Way have been seen in visible light for the first time. The gas’s motion shifts the light’s wavelength, as depicted in this illustration.

A digram showing where the Fermi Bubbles (red) overlap with the hourglass-shaped X-ray structures (black) at the galaxy's center. The edges of the two structures seem perfectly aligned, the ...

The Fermi bubbles are giant blobs of plasma, tens of thousands of light-years tall, that extend on either side of the Milky Way’s galactic disk. When the bubbles were discovered in 2010, ...

The team suggests the bubbles—named the eRosita bubbles after the telescope that found them in 2020—are the result of powerful jet activity launched by the Milky Way's supermassive black hole ...

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.
