An international team of astronomers, including one from the University of Cape Town (UCT), has spotted a very rare sight in the early Universe: a galaxy that appears as an “Einstein Cross” – four ...

We’ve grown up with the idea that the universe will expand forever, meaning that something called the “cosmological constant” is positive. Space keeps stretching, galaxies drift farther apart, and ...

The following games are classics in their own right, and well worth playing on their merits, but I'd stop short of calling them science fiction. The Borderlands series has big personalities, big guns, ...

Galaxies "blazing with technosignatures" could suggest the existence of a "large number" of "different metasocieties." The Fermi Paradox, first devised by physicist Enrico Fermi in the 1950s, asks why ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

The James Webb Space Telescope's latest image shows eight spectacular examples of gravitational lensing, a phenomenon that Albert Einstein first predicted some 100 years ago.

But a new study suggests that neither dark matter nor dark energy may actually exist. Instead, what scientists see as these mysterious forces could simply be an illusion, created by the slow weakening ...

Exoplanet hunters Christopher Watson and Annelies Mortier explain the long search for a 'twin Earth' capable of sustaining life.

Astronomy is, in essence, an exercise in inference. We cannot touch the stars, nor scoop up galaxies in a lab. Instead, we decipher the universe through its light — its color, intensity, rhythm and ...

The first fast radio burst, or FRB, was discovered in 2007 in archival data collected back in 2001, and scientists were pretty boggled. Lasting just milliseconds, the incredibly powerful spike of ...
