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 bubble ...

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

A surprising discovery at the heart of the Milky Way is forcing scientists to rethink how massive structures called Fermi ...

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, ...

Readings from Green Bank Telescope detect cloud made of cold hydrogen gas inside bubbles of superheated plasma.

The Fermi bubbles were discovered in 2010 by NASA’s Fermi Gamma-ray Space Telescope. The two orbs form an hourglass structure ...

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.

The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the finding refines our understanding of the properties of these mysterious blobs.

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.

Similar bubbles can be seen in other galaxies, but it's still impossible to say whether the Fermi bubbles were produced by the same mechanism as the others, Meng continued.
