Tests in London and Singapore could reveal whether AI can improve the safety of air travel

To mark its third year of highly productive science, astronomers used the NASA/ESA/CSA James Webb Space Telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region.

Trump abruptly announced the appointment of Secretary of Transportation Sean Duffy as acting NASA Administrator as the U.S. Senate reviews the space agency's proposed budget.

Astronomers tracking an interstellar object flying through the solar system think it comes from a star at least 8 billion years old, almost twice the age of our sun

Walmart is serving up some hot anti-Prime Day deals on Canon EOS R cameras with hundreds of dollars off the best models!

The scientific and cultural impact of 3I/ATLAS over the coming months and years will serve as an exemplar of what astronomy can learn and why it matters.

As Earth spins faster than it has in decades, atomic clocks are catching the difference, and shorter days are on the horizon.

If Americans don’t fight back against efforts to dismantle higher education, the U.S. will lose lifesaving medical research, innovation that spurs our economy and the ability to freely study science and society

Although dark matter doesn't seem to interact with regular matter or itself, if it has particle-like properties, it could self-annihilate if packed into a tight space. In a new paper, researchers have proposed that dark matter could make its way into brown dwarfs near the Galactic Center, where everything is packed more closely together. The dark matter could annihilate inside the brown dwarfs, creating Dark Dwarfs that could be detected.

Gravitational waves come in all shapes and sizes - and frequencies. But, so far, we haven’t been able to capture any of the higher frequency ones. That’s unfortunate, as they might hold the key to unlocking our understanding of some really interesting physical phenomena, such as Boson clouds and tiny block hole mergers. A new paper from researchers at Notre Dame and Caltech, led by PhD student Christopher Jungkind, explores how we might use one of the world’s most prolific gravitational wave observatories, GEO600, to capture signals from those phenomena for the first time.

We all know what it's like when Earth is on the receiving end of a solar flare. Things get spicy in the upper atmosphere, and the outbursts have the potential to disrupt technology here at home. Catastrophic flares of radiation devastate planets around other stars, too. Now it looks like scientists have found that planets orbiting close to their stars can trigger the flares that threaten to harm them.

NASA's Curiosity Rover has been exploring Gale Crater and found that carbonate materials make up to 11% of rocks in the region. These are important because carbonates formed by pulling CO2 out of Mars's atmosphere. A new paper suggests that Mars once had a self-regulating climate system that created oases of liquid water on its surface over billions of years, keeping the planet barely habitable with alternating wet and dry periods. The atmosphere is thin because its CO2 was locked away in rocks.

Here's a thought experiment. What would happen if you were on the International Space Station, folded up a paper airplane, and threw it from the station? According to a new paper, it would fall from orbit in just 3.5 days, but still keep aerodynamic stability until about 120 km. Then it would heat up and combust at about 90-110 km altitude. It's a fun idea, but there are actual practical uses to probe the density of the atmosphere or test thin-film space technologies.

The James Webb Space Telescope (JWST) can tell us a lot about the subjects of its observations if it spends enough time with them. That includes lonely rocks on the edges of our solar system, such as the Trans-Neptunian Object (TNO) Quaoar. Recent observations using the NIRCam on JWST and pre-published on arXiv by researchers at the University of Central Florida, the Space Telescope Science Institute, and Kyoto University add a plethora of new data to our understanding of this enigmatic object, including insights into what might be causing its ring system and its hydrocarbon atmosphere.

The long-awaited Vera Rubin Observatory has delivered some preliminary observations of the globular cluster 47 Tucanae field. 47 Tuc is the Milky Way's second-brightest globular cluster, second to Omega Centauri. The Rubin Observatory's data demonstrates the telescope's promising scientific potential.
