Space dragons: Researchers observe energy consumption in quasars

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 ...

Astronomers reveal true colors of evolving galactic beasts

Astronomers have identified a rare moment in the life of some of the universe's most energetic objects. Quasars were first observed 60 years ago, but their origins still remain a mystery. Now researchers at Durham University, ...

Astronomers find quasars are not nailed to the sky

Until recently, quasars were thought to have essentially fixed positions in the sky. While near-Earth objects move along complex trajectories, quasars are so remote that they were believed to offer stable and reliable reference ...

Energy loss gives unexpected insights in evolution of quasar

An international team of astrophysicists observed for the first time that the jet of a quasar is less powerful on long radio wavelengths than earlier predicted. This discovery gives new insights in the evolution of quasar ...

SDSS J1430+1339: Storm rages in cosmic teacup

Fancy a cup of cosmic tea? This one isn't as calming as the ones on Earth. In a galaxy hosting a structure nicknamed the "Teacup," a galactic storm is raging.
