The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

Astronomers have created an enormous 3D map of the universe revealing a glowing “sea of light” from hydrogen gas during the cosmic dawn nearly 11 billion years ago.

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

The discovery of the universe’s oldest stars, identified within our own Milky Way galaxy, marks a significant leap forward in our understanding of cosmic history. These ancient stars, formed shortly ...

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 ...

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...

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 ...

A new study has estimated the universe’s possible age by using precise data on stars.

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 ...

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 ...

Astronomy studies celestial objects and phenomena beyond Earth. Astronomy degrees offer specializations like cosmology, planetary science, and stellar astrophysics. Astronomers use telescopes, math, ...
