Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...

How space telescopes capture distant galaxies using infrared imaging, precision optics, and astronomy technology beyond Earth's atmosphere.

Following the announcement that Amazon has given a new 'Stargate' the go-ahead, franchise figureheads Martin Gero and Joseph Mallozzi shared some of the details.

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations ...

"JADES-ID1 is giving us new evidence that the universe was in a huge hurry to grow up." ...

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

Scientists using NASA's James Webb Space Telescope now think the "little red dots" spotted in the early universe could be a new kind of space object. They call it a "black hole star." Credit: T.

A team of researchers proposes a new vision of the Universe's first moments. Their model eliminates the need for traditional speculative hypotheses. Cosmologists have long worked with the inflation ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...

Though sci-fi movies would have us believe that space is incredibly cold — even freezing — space itself isn't exactly cold. In fact, it doesn't actually have a temperature at all. Temperature is a ...
