Astronomers say they have discovered a hot, star-popping galaxy that is far, far away — farther than any previously detected, from a time when the universe was a mere toddler of about 400 million ...

Some galaxies hit a point in their lives when their star formation is snuffed out, and they become “quenched.” Quenched galaxies in the distant past appear to be much smaller than the quenched ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

Research led by Daniel Ivanov, a physics and astronomy graduate student in the Kenneth P. Dietrich School of Arts and Sciences at Pitt, uncovered a contender for one of the earliest observed spiral ...

The motion of any object is relative. On Earth we tend to ignore that, because the vast background of the ground gives us a seemingly fixed and absolute frame of reference. Sitting comfortably at our ...

The galaxy cluster Ophiuchus was doing just fine until WISEA J171227.81-232210.7 — a black hole several billion times as massive as our sun — burped on it. By Dennis Overbye If there were ever ...

Imagine peering into a nursery and seeing, among the cooing babies, a few that look like grown men. That’s the startling situation that astronomers have stumbled upon as they’ve looked deep into space ...

Hubble has captured a galaxy losing vital gas as it races through a crowded cluster, revealing how harsh cosmic environments ...
