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.

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

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

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

Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, ...

As a science communicator, I don’t think a week goes by without a press release hitting my inbox informing me of astronomers finding some new record-breaking object. Sometimes it’s the smallest planet ...

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 ...
