Universe

The James Webb Space Telescope keeps breaking its own records for peering deeper into space and time. It's now detected a galaxy candidate about 35 billion light-years from Earth, which if confirmed would make it the most distant galaxy ever found.

Everything has to end eventually – including the universe itself. It might be hard to imagine a catastrophe big enough to affect the entirety of existence, but here are some of the leading hypotheses about how the universe could end, and when.

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.

Data from DESI's first survey run has produced the largest and most detailed 3D map of the universe so far. The stunning image reveals the gigantic cosmic web of galaxies across billions of light-years – and the project is only just beginning.

Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust, and the find suggests that there were far more galaxies in the early universe than previously thought.

How did the universe end up with exactly the amount of dark matter needed? A new model suggests dark matter particles in the early universe converted regular matter into dark matter exponentially, before being slowed by the expansion of the universe.

Astronomers have proposed a novel solution to one of the many mysteries of black holes – why do so many seem to be more massive than expected? A new model suggests that their growth may be “cosmologically coupled” to the expansion of the universe.

Planets rotate, stars rotate, galaxies and galaxy clusters all rotate. Astronomers have now discovered evidence that larger scale structures of the universe also rotate – mind-bogglingly gigantic filaments that pipe galaxies around the cosmos.

Why is the expansion of the universe accelerating? The leading hypothesis is a repellent force that astrophysicists refer to as “dark energy." But how does it work? What does it mean for our future? And how sure are we that it even exists?

The expansion of the universe is accelerating, and current models call the driving force dark energy. But perhaps this placeholder doesn’t exist – a new study has found that dark matter could produce the same effect if it had some form of magnetism.

On a scale that’s hard to fathom, the universe is structured like a “cosmic web." Astronomers have now directly observed light from filaments in this web, by staring at a patch of sky with a deep-field telescope to detect faint dwarf galaxies.

NRAO has announced a new addition to NASA’s upcoming moon-shot Artemis program. From the silent skies on the far side of the Moon, the DAPPER spacecraft will listen out for radio signals from the cosmic “Dark Ages,” before the first stars fired up.
