The ESA (European Space Agency) has revealed an example of gravitational lensing, in which enormous celestial objects bend ...

Astronomers have identified what may be the first example of a new class of radio galaxy, one whose central black hole ...

Look up on a clear night away from city lights, and you might spot a faint smudge that isn't a star at all. It's a galaxy, a ...

Last month, the European Space Agency (ESA) released a huge dataset from its space telescope Euclid. The release featured three deep-field mosaics glittering with 380,000 galaxies and hundreds of ...

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called COSMOS ...

Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest ...

A whole universe of hidden galaxies lies just beyond what the eye can see. Thanks to a new generation of space telescopes, astronomers are now revealing these distant, dim worlds—some no bigger than a ...

A newfound object uncovered in the early universe by NASA’s James Webb Space Telescope (JWST) is challenging long-held ideas about how galaxies form. Dubbed the “Big Wheel,” it’s a galaxy much like ...

The Universe is chock-full of oddities: stars that blink in and out without explanation, galaxies that eat one another, black holes gone rogue. It’s no surprise that among the billions of galaxies out ...

Ultra-faint dwarf galaxies – tiny satellite galaxies orbiting the Milky Way – have long been seen as cosmic fossils. Now, a new study published April 24, 2026, in the peer-reviewed journal Monthly ...

PHOENIX —Thousands of newly spotted galaxies are dressed for a Victorian ball: in hoop skirts. The cache of “polar structure galaxies” — with large starry or dusty structures oriented perpendicular to ...
