A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.
The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.
The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...
Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between ...
When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact ...
The researchers said that the "hydroxyl gigamaser" was generated by the merger of two galaxies some 8 billion light-years away.
