The narrowest magnetic loops ever seen in the sun's corona have been imaged by the most powerful solar telescope on Earth.
A mysterious lunar landslide might have been caused by debris from a faraway crater-forming impact, new analyses of Apollo 17 moon samples suggest.
The impending merger of the two galaxies hints at what might be in store for the Milky Way and the Andromeda galaxy if and when they collide.
Astronomers have learned how to find supernova explosions in their earliest stages, giving us an unprecedented look at how these stars blow up.
Two exotic new theories suggest dark matter could be either made from tiny black holes or formed by Hawking radiation at the cosmic horizon.
As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.
The star, called DFK 52, is a member of a cluster of similar red supergiants, but it's losing mass at an extreme rate never seen before.
Nicknamed 'Punctum,' this puzzling phenomenon is highly energetic, but is only seen in millimeter-wavelength light and cannot be explained by any known object.
As space becomes more important to the economy of nations around the world, the risk of paper mills flooding the literature with fraudulent results is increasing.
The techniques used to target the asteroids could also be employed in tracking hazardous asteroids and interstellar objects.
New Hubble Telescope imagery of the interstellar interloper comet 3I/ATLAS reveals a dusty coma and the beginning of a tail.
Electrons released when cosmic rays strike water-ice can provide energy for microbes and facilitate the formation of complex organic molecules.
The image reveals over 2,500 galaxies, many of which are seen as they were during the first billion years of cosmic history.
A beam of particles speeding away from a monstrous black hole is severely kinked, suggesting that the black hole is actually part of the most extreme binary system known.
A new version of the famous double-slit experiment showed that it's impossible to measure light as both a wave and a particle at the same time, thanks to quantum physics' uncertainty principle.
The James Webb Space Telescope's investigations of the planetary nebula NGC 6072 suggest a second star played a hand in sculpting the death of the primary star.
A retraction intends to bring to an end the acrimonious debate about the validity of the 15-year old findings that threatened to upend what we thought we know about life.
The Hubble Telescope and Chandra X-ray Observatory saw an enigmatic intermediate-mass black hole lighting up in X-rays, potentially revealing a way of finding more of them in the future.
Although the antimatter qubit won't find use in quantum computing, it will be used to test the differences between matter and antimatter.
Protected regions of the ocean are doing their job and keeping illegal fishing at bay, according to new research combining satellite imagery with artificial intelligence.
NASA's TRACERS mission blasted off July 23 on a Falcon 9 rocket with three other small agency satellites that will act as technology demonstrators to monitor space weather.
NISAR, a joint mission of NASA and ISRO set to launch on July 30, will be able to see shifts in the landscape smaller than a centimeter to give warning of potential natural disasters.
The new TRACERS mission will track magnetic reconnection that drives particles down into Earth's atmosphere when space weather turns bad.
