'We were amazed': Scientists find hidden structure in nebula captured by James Webb telescope
Submillimeter wavelength radio observations of the Southern Ring Nebula have identified that it's actually a double ring, shaped by the interactions of three stars.
Jupiter may be the reason why Earth has a moon, new study hints
The great planetary instability, which saw Jupiter and the other gas giants wander chaotically through the solar system, coincides with the collision that formed Earth's moon. Could the two events be linked?
Astronomers reveal one of the most detailed pictures of an exploded star ever taken
Astronomers have taken the most detailed image of the Vela supernova remnant ever. The stunning, 1.3-gigapixel image is also the largest ever released from the Dark Energy Camera.
The James Webb telescope may have found some of the very 1st stars in the universe
The James Webb Space Telescope zoomed in on galaxy GN-z11, which existed just 430 million years after the Big Bang, to reveal what may be some of the oldest stars in the universe.
The universe might be younger than we thought, galaxies' motion suggests
We think the universe is 13.8 billion years old, but could we be wrong? A new study of bound galaxies offers an unexplored clue.
2-mile-thick layer of frozen water found buried at Mars' equator
The Mars Express orbiter has detected enough water ice buried beneath the Red Planet's equator to cover the entire planet in a shallow ocean if melted.
Scientists find ultra-rare collection of molecules in 2 ancient galaxies from the early universe
Scientists discovered 13 molecules, including some never spotted before in the early universe, inside two galaxies located 12 billion light-years away.
Strange object trapped between Saturn and Uranus is transforming before our eyes
A distant comet trapped in orbit between Saturn and Uranus is accompanied by a transforming disk of icy dust, new observations reveal.
Large Hadron Collider could be generating dark matter in its particle jets
If dark matter is made from "dark" versions of the basic building blocks of ordinary matter, the world's largest particle accelerator should be able to pin it down, a new study suggests.
'Significant and unexpected': Dying star spits out a sun's worth of mass just before going supernova
A supernova, pinpointed by amateur astronomers, could reveal unexpected new steps in the deaths of massive stars.
Brightest supernova of past 420 years revealed in stunning new James Webb telescope images
This supernova signaled the explosive death of a supergiant star in the nearby Large Magellanic Cloud.
Mars had an extreme climate shift 400,000 years ago, Chinese rover finds before its demise
China's presumed-dead Zhurong rover spotted telltale patterns of ancient climate change in the Martian dunes.
Rare 'warped' supernova revealed through space-time phenomenon predicted by Einstein
The gravity of a galaxy two-and-a-half billion light-years away has acted like a cosmic magnifying glass to amplify the light of a distant exploding white dwarf.
