The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy ...

"Cosmic archaeologists" have discovered an iron-deficient second-generation star, which provides evidence of how ancient ...

Science in the modern era is increasingly reliant on enormous datasets and automated analysis. In astronomy, the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST)—a ten-year survey ...

A weekly video series on astronomy, hosted by Dave Eicher and sponsored by Celestron, will run throughout 2023. The series will cover current astronomical events, research findings, and cosmic enigmas ...

We have made our own gravity wave detectors on Earth that are about 40 kilometers long and detect variation with lasers and now we have used decades of Pulsar observations to detect long wave gravity ...

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids, which will from now on be discovered at an astonishing rate as it begins ...

The night sky appears perfectly still, but the universe is constantly changing in ways the human eye cannot see. By combining ...

Astronomers have detected strange "wobbles" in the light curve of a super bright supernova, hinting that a magnetar was born inside the extreme stellar explosion.

Just how large is the universe? The short answer is 93 billion light-years — at least. That 93 billion light-year number refers to what astronomers call the observable universe, and it extends about ...

Astronomy graduate students at San Diego State University are in the middle of their semester doing something that, of course, is out of this world. At an elevation of 6,100 feet, Mount Laguna ...

One of astronomy's biggest puzzles may have been solved by a new theory that suggests the universe may rotate at an extremely slow rate. Current models suggest the universe is expanding evenly in all ...
