Astronomers have discovered over a dozen “dormant” galaxies that paused their star formation within the first billion years after the Big Bang. The discovery, made with data from the James Webb Space Telescope (JWST), illuminates a fascinating phase in the lives of early galaxies and could provide more clues about how galaxies evolve. There are several reasons why galaxies may …

Two of the strangest structures in the galaxy just got even stranger. Ballooning above and below the Milky Way‘s center like a massive hourglass, the mysterious Fermi bubbles loom large over our galaxy. These enormous twin orbs of superheated plasma have been gushing out of the galactic center for millions of years. Today, they span some 50,000 light-years from tip …

Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so destructive and extreme that they create disturbances in spacetime more like powerful waves than small ripples, with enough energy to reach our own detectors here on Earth.  Today, the LIGO Collaboration …
