Using the James Webb Space Telescope, astronomers have investigated 70 dusty galaxies at the very edge of the universe that challenge our understanding of cosmic evolution.

In last week’s The Universe column, I fielded a reader’s question about galaxy collisions in an expanding universe. The answer deals with vast distances, inscrutable forces and the ultimate fate of ...

Astronomers have spotted what may be one of the universe’s earliest barred spiral galaxies — a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, ...

Recent research suggests that galaxies with high radio emissions—known as “radio-bright” galaxies—could be home to alien civilizations. This idea, explored in Brian C. Lacki’s study Artificial ...

Add Yahoo as a preferred source to see more of our stories on Google. Mysterious blasts of radio waves from across the universe called fast radio bursts help astronomers catalog matter. ESO/M.

Radio telescopes have long scanned quiet patches of sky for a lone, artificial-sounding ping, but a growing body of research is pushing astronomers to look instead at the loudest neighborhoods in the ...

The "afterglow" of the universe is an important piece of evidence for the Big Bang. This background radiation also provides important answers to the question of how the first galaxies were able to ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe. When you ...

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 ...

An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion ...
