Tokyo, Japan – A scientist from Tokyo Metropolitan University has shown that large gamma-ray emitting bubbles around the center of our Galaxy were produced by fast blowing outward winds and the ...

Image: From end to end, the newly discovered gamma-ray bubbles extend 50,000 light-years, or roughly half of the Milky Way’s diameter, as shown in this illustration. Hints of the bubbles’ edges were ...

1. What Are Fermi Bubbles? No, this is not a rare digestive disorder. The bubbles are massive, mysterious structures that emanate from the Milky Ways center and extend roughly 20,000 light-years above ...

A single gamma-ray burst has forced astronomers to redraw their mental map of how the most violent explosions in the universe ...

Fermi Bubbles have become more bewildering to astronomers. Recently, scientists announced the presence of two massive clouds inside these structures using the Green Bank Telescope. This discovery, if ...

For nearly a century, scientists have been searching for direct evidence of dark matter—one of the key missing pieces of our theoretical understanding of the universe. While we have glimpsed the ...

Each lobe of the Fermi bubbles is 25,000 light-years tall. NASA's Goddard Space Flight Center In the center of our galaxy, gigantic, balloon-like structures of high-energy radiation extend thousands ...

Astronomers have detected an enormous gamma-ray bubble that could be a source of the Milky Way’s most powerful cosmic rays — high-energy particles that rain down on Earth from space. The turbocharged ...
