On Thursday, April 24, 2025, the Hubble Space Telescope will celebrate 35 years in space. Can it still hold its own and prove useful when compared to instruments like the James Webb Space Telescope?

A massive clump of dark matter in the Perseus galaxy cluster is linked to its core by a bridge of dark matter, evidence of a history of mergers.

Using the James Webb Space Telescope, astronomers have discovered "smoking gun" evidence of a hidden feeding supermassive black hole in a distant spiral galaxy.

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.

Using the Hubble and Gaia space telescopes, astronomers have discovered that a powerfully magnetic neutron star in the Milky Way wasn't born in a supernova.

Astronomers have discovered the weirdest planetary system ever seen, consisting of a planet rolling around rare binary "failed star" brown dwarfs at a 90-degree tilted angle!

Scientists have developed a cosmic car radio that could tune into the frequency of axions, a prime dark matter suspect.

The James Webb Space Telescope has spotted the most distant spiral galaxy ever seen, a "Milky Way twin" that existed 1 billion years after the Big Bang.

A new cosmic model suggests that singularities could briefly pop into existence, spewing matter and energy into the cosmos, negating the need for dark energy and dark matter.

NASA astronaut Don Pettit and two cosmonaut colleagues will return to Earth from the International Space Station on Saturday night (April 19), if all goes to plan.

The universe could be packed with dark matter haloes that have no galaxy fillings.

The Large Magellanic Cloud and Small Magellanic Cloud are at war, with the larger of these dwarf galaxies ripping the other apart.

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.
