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

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 ...

Back in 2010, scientists spotted something shocking: a pair of gigantic, glowing lobes of gas bursting from the Milky Way’s center. These were the Fermi Bubbles, discovered with gamma-ray vision, and ...

Astronomers have made a surprising discovery at the heart of our galaxy—the Milky Way. They’ve found cold clouds of gas floating inside the blazing-hot Fermi bubbles, enormous structures of ...

Fresh evidence claims that the Earth and the surrounding galaxy are suspended inside a cosmic void based on echoes from the ...
