Story summary

Astronomers have unearthed 11 frigid hydrogen clouds nestled within the Fermi Bubbles, dynamic gas lobes soaring above the Milky Way. This remarkable discovery, likened to "ice cubes in a volcano," defies current theories on how galaxies recycle matter. With masses reaching 1,470 solar masses and potentially millions of years old, these clouds could revolutionize our grasp of galactic evolution.
