Astronomers have traced the origin point of a jet of material that is thousands of light-years long emanating from the ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

Astronomers using the James Webb Space Telescope (JWST) keep finding the same impossible thing: ancient supermassive black holes; monsters millions of times the sun’s mass, existing when the cosmos ...

Astronomers using the Event Horizon Telescope (EHT) have uncovered a major clue in the mystery of how black holes produce ...

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

Using the world's most powerful particle accelerator, CERN's Large Hadron Collider, scientists have discovered that the ...

New Event Horizon Telescope observations reveal the first direct link between the supermassive black hole M87* and its 3,000-light-year plasma jet, showing how energy from near the event horizon ...

Dark stars powered by dark matter may explain bright galaxies, massive black holes, and mysterious red objects in the early universe.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

The venerable Hubble observatory is going strong despite its decades in space and the advent of next-generation successors ...
