Astronomers have used space-based telescopes, including NASA's Swift X-ray observatory, to watch a monster black hole spring to life with powerful X-ray eruptions.

Using the Hubble Space Telescope, astronomers have, for the first time, directly detected the merger of star clusters at the heart of dwarf galaxies.

Black holes power some of the most energetic phenomena in the known universe, but could they ever power an advanced human civilisation?

An extreme protocluster gathering of infant galaxies is hiding a vast cosmic fuel tank that is powering 400 million years of intense star formation.

The most distant and earliest "dead" massive galaxy ever seen shows some galaxies lived fast and died young shortly after the Big Bang.

New findings from the ALMA telescope have revealed that planets are born in much smaller protoplanetary disks than astronomers suspected, some of which would fit with the orbit of Earth.

Dark energy may have a completely unknown aspect of physics acting as an accomplice in its efforts to defy gravity, suppressing the growth of large-scale structures like galaxy superclusters.

A group of stellar Sherlocks have solved the mystery of red transient objects that appear and fade in the sky, linking them to the total explosive death of stars.

A strange blue spiral lit up the sky over Europe on Monday night (March 24), with residents of the UK and other countries speculating on its true nature on social media.

The observation of titanic jets emerging from the supermassive black hole at the heart of a distant galaxy could be a grim prediction of the Milky Way's future.

Using data from the Euclid Space Telescope, astronomers have discovered a stunning 2,674 dwarf galaxies, the study of which could help better understand cosmic evolution.

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

Astronomers have examined infant planets orbiting a star 370 light-years away, seeing the exomoon forming disks of gas and dust around them in unprecedented detail.

Astronomers have discovered filaments of matter swirling tornado-like around the heart of the Milky Way, home to the supermassive black hole Sagittarius A*.

The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of cosmic evolution could be wrong.

Astronomers have discovered oxygen and heavy elements in the earliest galaxy ever seen, suggesting some galaxies as early as 300 million years after the Big Bang matured early.

New research suggests that life could have the time and energy to arise on Earth-like worlds in the rapidly shrinking "Goldilocks zones" around white dwarf stars.

Using the now-retired Kepler space telescope, astronomers have discovered that larger planets grow up in more turbulent homes than smaller worlds.

The Euclid space telescope has dropped its first data and deep field observations showing millions of galaxies in great detail as it hunts for dark matter and dark energy clues.

The clearest and most precise images yet of the universe’s infancy from the Atacama Cosmology Telescope show the first steps toward the first stars and galaxies.

The James Webb Space Telescope is investigating the Flame Nebula, hunting for "failed stars" to better understand how brown dwarfs form and evolve.

The moon will turn blood red overnight on Thursday and Friday during the 'Blood Moon' total lunar eclipse. How can you tell what images of this event are the real deal?

The James Webb Space Telescope has found perhaps its most profound discovery to date. The uncovered preferred direction for galaxies supports the idea that the universe was born in a black hole.

Astronomers have traced a starnge blast of radiowaves that repeats every 2 hours back to a dead star white dwarf magnetically slamming its stellar companion.
