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

Astronomers have found 11 unexpectedly cold hydrogen clouds hiding in the superheated turbulence of the Fermi Bubbles, in a ...

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

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 ...

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

"The Fermi bubbles are enormous structures of hot gas that extend above and below the disk of the Milky Way, reaching about 25,000 light years in each direction from the galaxy's center ...

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, ...

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.

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.

Today, those blobs — now named the Fermi Bubbles — span half the width of our galaxy. One lobe towers for 25,000 light-years above the Milky Way's disk, and the other looms just as large below ...

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 ...

Twin shock waves produced by the galaxy's central black hole could have inflated the gargantuan Fermi Bubbles about 6 million years ago, a new study suggests. Skip to main content.
