In a new study published in The Astrophysical Journal Letters, a team of astronomers has uncovered extraordinary details about the forces shaping the merging galaxy system Arp 220. Using the advanced ...

Astronomers have spotted the most distant and brightest "space laser," or megamaser, ever seen, and it's blasting out from a collision between galaxies that occurred when the universe was just half ...

Astrophysicists trace the origin of valuable metals in space, from colliding stars to merging galaxies by Simone Dichiara, Eleonora Troja, The Conversation edited by Gaby Clark, reviewed by Andrew ...

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a close pair of quasars, which is a result of a distant massive galaxy merger. The detection of the quasar ...

Learn how two galaxies slowly pulling toward each other inspired a name that captures their cosmic collision and the birth of new stars within them. The constellation Pegasus has long been associated ...

The process of galaxy merging reshapes cosmic structure by driving dramatic changes in the distribution and state of interstellar gas, thereby governing the rates and locations of star formation.

Six interacting galaxies spotted 12 billion light-years away hint at how the universe’s largest galactic structures first assembled Al is a long time tech writer with a penchant for all things nerdy.

(THE CONVERSATION) Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and ...
