Astronomers studying how star formation evolved over cosmic time have discovered that quiescent galaxies (galaxies that are currently not making many new stars) frequently have active galactic nuclei. These AGN accrete material ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due ...

You may have heard that nothing escapes the gravitational grasp of a black hole, not even light. This is true in the immediate vicinity of a black hole, but a bit farther out—in disks of material that swirl around some ...

A team of researchers from Russia and Greece reports a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3-D image by feeding each ...

Jeremy Schnittman, an astrophysicist at NASA's Goddard Space Flight Center has taken what he describes as a tongue-in-cheek look at the issues that might stand in the way of life existing on a planet orbiting a black hole. ...
This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole where infalling matter ...

Quasars are the universe's brightest beacons; shining with magnitudes more luminosity than entire galaxies and the stars they contain. In the center of this light, at the heart of a quasar, researchers think, is an all-consuming ...
