Two giant, mysterious bubbles spew from the Milky Way’s heart, and now it appears the bubbles may have doubles. Previously, researchers had seen an X-ray arc above the galactic plane (SN: 7/8/20). But ...

Millions of years ago, a powerful explosion shook the center of the Milky Way, sending twin shock waves blasting across the sky. Those waves bulldozed through the galaxy, heating up all the gas and ...

Everyone is familiar with tiny gas bubbles gently rising up in sparkling water. But the bubbles that were created by intense focused lasers in this experiment were ten times smaller and contained ...

Two towering “chimneys” glowing with X-rays extend from the center of the Milky Way. The newly discovered structures could help explain the source of two even larger features: giant bubbles that emit ...

Two giant bubbles of gamma rays and X-rays that erupted from the center of the Milky Way may stem from a supermassive black hole's feeding frenzy at the heart of the galaxy, a new study finds.

The center of the Milky Way is a busy place. The galaxy's core is bustling with a supermassive black hole, the birth of thousands of stars, and their explosive deaths. And now, a team of astronomers ...

A giant structure around our Milky Way galaxy has been discovered by the NASA Fermi Gamma-ray Space Telescope [1]. Gamma ray emitting bubbles are symmetrically attached at either side of the plane of ...

Two enormous gamma-ray bubbles extend 25,000 light-years above and below the Milky Way's center. These bubbles are extremely energetic, equivalent to the energy of 100,000 supernovae. Gamma rays are ...

Astronomers just spotted a massive cosmic burp coming from the center of our galaxy. The fiery bubble of plasma is expanding more than 45,000 light-years below the Milky Way Galaxy and emitting ...
