A team of Chinese researchers has found a giant bubble of ultra-high-energy gamma rays in the Cygnus region of the Milky Way, which reveals the origin of the most energetic cosmic rays ever detected.

In the heart of our Milky Way galaxy, two gigantic "bubbles" extend roughly 50,000 light-years above and below the galactic ...

The highly energetic explosion was initially attributed to a burst of gamma rays emitted either by the collision of two neutron stars or from the death of a massive star. Soon, however ...

For years, astronomers have been puzzled by the presence of two gigantic, high-energy “bubbles” towering over and beneath the Milky Way’s center, extending 50,000 light-years into space. First ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
