Jeremy Darling from the University of Colorado Boulder proposes an original approach to measure the gravitational wave ...

In a remarkable observation deep in the cosmos, astronomers have captured an intense interaction between two galaxies that ...

The moment one galaxy spears another with a powerful beam of radiation shooting from its central black hole has been spotted in a distant galactic collision.

“We hence call this system the ‘cosmic joust’,” study co-lead Pasquier Noterdaeme, a researcher at the Institut ...

Astronomers have observed two distant galaxies — both possessing roughly as many stars as our Milky Way — careening toward ...

Observations show a stronger galaxy piercing a weaker one with a lance of radiation, reducing its star-making ability.

Astronomers caught a brutal act of cosmic violence for the first time—one galaxy piercing another with deadly radiation.

As one galaxy smashed into the other, the winner pieced its cosmic victim, leaving behind a high level of radiation in a ...

The quasar’s radiation is stripping away gas in its companion galaxy, leaving behind clumps too compact to form new stars.

Scientists have been baffled after spotting two galaxies entangled in a 'cosmic joust', with one galaxy wielding a deadly 'spear of radiation'.

The pair — dueling it out 11 billion light-years away in space — has given astronomers their first detailed look at a galaxy ...
