KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

The vast "sheet" of dark matter could explain why almost all of our galactic neighbors are running away from us.

Astronomers have discovered how "forever young" stars stay blue and bright despite being almost as old as the universe.

A "crowdsourced" project in which home computer users were enlisted to help analyze radio signals from space is ending after ...

Using the world's most powerful particle accelerator, CERN's Large Hadron Collider, scientists have discovered that the trillion-degree hot primordial "soup" that filled the cosmos for mere millionths ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

The James Webb Space Telescope has observed the earliest galaxy ever recorded, only 280 million years after the Big Bang.

Astronomers at Texas A&M University have discovered a rare, tightly packed collision of galaxies in the early universe, suggesting that galaxies were interacting and shaping their surroundings far ...

NASA’s James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright ...

Synchrotron radiation has revealed a star map made by the ancient astronomer Hipparchus that was thought to be lost to time ...

MoM-z14 existed just 280 million years after the Big Bang, according a team of astronomers led by Dr. Rohan Naidu from the ...
