Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion ...

Despite sounding like something out of pulpy '50s sci-fi, 'space lasers' are real – and astrophysicists have now spotted the brightest and most distant one yet. This 'gigamaser' is blasting out of a ...

Seen as it was 8.5 billion years ago, the galaxy shows that the early universe was harsher than scientists previously thought ...

Astronomers have spotted a galaxy so faint, it's almost invisible — a discovery that could help illuminate one of the most elusive substances in the universe.

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

“The Euclid data clearly confirm the presence of the extremely faint, diffuse light of CDG-2, revealing the galaxy behind the ...

A rare gravitationally lensed supernova called SN 2025wny appears in five separate images due to the gravity of two ...

Astronomers discovered a dim, nearly undetectable galaxy which exists as a dark matter-dominated celestial body through their study of Hubble Space Telescope and other observatories' data.

The researchers said that the "hydroxyl gigamaser" was generated by the merger of two galaxies some 8 billion light-years away.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...
