Scientists have a new explanation for the odd behaviour of the mysterious comet

Astronomers on Monday warned that the light pollution created by the soaring number of satellites orbiting Earth poses an "unprecedented global threat to nature".

The satellite was put into orbit 312 miles up. Data from the long-running mission helped scientists better understand the formation of these unique clouds, also called night-shining...

Researchers pored over images from Magellan's visit to Venus in the early 1990s.

Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.

A new study looks at what it takes to survive beyond Earth, raising serious questions about whether or not human migrations to space is "Inevitable."

Like a "chorus of tiny voices," two new research papers suggest that black holes may generate the energy propelling the universe's rapid expansion

Astronomers have discovered a "runaway" black hole, potentially the first observational evidence that supermassive black holes can be ejected from their host galaxies.

Huge systems appear to be far larger than was presumed possible so early after big bang, say scientists

Our Solar System is odd because it has no Super-Earth. But what would happen if it did? Simulations show that we're better off without one.

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The new images reveal the surprising weblike structures the stars create inside galaxies as they evolve.

Evolution has shaped the load-bearing skeletons of animals over aeons with incredible precision. Now, an accelerated simulation of the evolution process is helping NASA create stronger, lighter parts for its spacecraft projects – in record time.

SpaceX has rolled a strange, naked Starship prototype from its Starbase, Texas factory to a nearby test site. Beginning with its cone-tipped nose section, SpaceX started stacking Starship S26 in October 2022. By early January 2023, the prototype had been stacked to its full 50-meter (~165 ft) height and welded together. After about six more weeks of outfitting, Ship 26 left Starbase’s High Bay assembly facility and was transported to one of two stands formerly used for suborbital Starship test flights.

This discovery offers new insights into the water history of Mars and the possibility of ancient life on the Red Planet.

The state of hibernation is much more than just sleep.

Astrophysicists propose geoengineering solution to climate warming, although skeptics still urge ‘massive’ fossil fuel cutbacks

EMU's role in the data collection process is to provide information on how the atmosphere interacts with cosmic rays.

Living in a rotating universe would be strange indeed.

Satellite navigation systems for lunar settlements will require local atomic clocks. Scientists are working out what time they will keep.
