The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field ...

The observed near flatness of galactic rotation curves has long been interpreted as evidence for large amounts of non-baryonic dark matter. Here we show that this phenom ...

By studying how light from eight distant quasars is gravitationally lensed as it propagates towards Earth, astronomers have ...

Astronomers have confirmed the earliest barred spiral galaxy in the universe, a Milky-Way-like structure that existed just 2 ...

A recent study provides answers to three seemingly disparate yet pressing cosmic dawn puzzles. Specifically, the authors show how dark stars could help explain the unexpected discovery of "blue ...

Astronomers used gravitational lensing to detect a supernova 10 billion light-years away, providing spatially separated images that help study cosmic expansion and early Universe events.

Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The ...

'This galaxy was developing bars 2 billion years after the birth of the universe,' says a researcher.

The gaseous cocoons surrounding "little red dots" hint at their true nature, a new James Webb telescope study hints.

Astronomers believe this barred spiral galaxy could be the oldest example of its kind ever observed. Research led by Daniel ...

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 ...

Researchers at the University of British Columbia and Dalhousie University have found a young galaxy cluster that appears far ...
