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.

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

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

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." ...

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 ...

An accidental discovery by a team of astronomers has upended existing theories about how galaxies formed in the early universe. The discovery, led by the "Cosmic Web" research group and international ...

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 ...

Workshop takes place Saturdays, 9/6, 9/20, 10/4, 10/18, and 11/1 from 10am - 12pm Pacific / 1pm - 3pm Eastern. Astro 101: Imaging the Universe with Your eVscope is a brand-new 5-part online workshop ...

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 ...

Members of the Case Western Reserve University community are invited to hear from Kelsey Johnson, professor of astronomy and director of the Echols Scholars Program at the University of Virginia, at ...

Instead of focusing on how fast the universe is expanding, they looked at the ages of some of the oldest stars in our galaxy.
