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

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

Twin orbs of superhot plasma at the Milky Way's center known as the "Fermi bubbles" contain inexplicable clouds of cold ...

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, ...

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.

Now known as the Fermi Bubbles, these massive, gassy blobs appear only in X-ray and gamma-ray light, teasing at an ancient and extremely powerful origin. How and when this galactic bubble-blowing ...

In 2010, astronomers discovered two giant blobs centered on the core of our Milky Way galaxy. Their origins are still a mystery, but however they got there, the blobs are emitting copious amounts ...

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 ...
