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

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 ...

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 13.

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.

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 ...

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 ...

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

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 ...

Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between galaxies that had remained otherwise hidden in previous surveys.

Using gravitational waves as a measure of the universe's rate of expansion could solve the biggest headache in physics, the so-called "Hubble tension." ...

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

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 ...
