Does consciousness depend on flesh and blood? The answer is almost certainly no, according to Eric Schwitzgebel, a distinguished professor of philosophy at the University of California, Riverside. In a new working paper, Schwitzgebel and Jeremy Pober, a former UCR graduate student who is now a postdoctoral researcher at the University of Lisbon, assert that […]
After only four short years, NASA’s James Webb Space Telescope (JWST) and observational cosmologists like Richard Ellis at University College London (UCL) have pushed the cosmic lookback time to an era when the universe’s very first stars and galaxies are within observational reach.

A compact, multifrequency radar built by a team at NASA’s Jet Propulsion Laboratory will make it easier to collect information about dynamic cloud systems. Called CloudCube, this new instrument simultaneously probes the atmosphere with three radar signals, spanning 36 to 240 GHz, for optimized sensitivity to a wide range of water droplet and ice particle […]
The moon may look unchanged from afar, but its surface is constantly reshaped by microscopic impacts and a steady stream of particles from the sun, a process known as space weathering. Now, Georgia Tech researchers have recreated one of those weathering sources, solar wind, in the lab—offering new insight into how the lunar surface evolves. […]
Our universe’s expansion is still accelerating despite recent claims suggesting otherwise, an international team of astrophysicists says.

The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces.

No matter the time or vantage point, from a pre-Neolithic cave to a post-lockdown London high-rise, the predictability of the night sky has always been humanity’s symbol of permanence and reassuring stability.

A new telescope technology—measuring just 6 millimeters (0.24 inches) in diameter—could improve how future space missions study and monitor the sun while simplifying onboard hardware and reducing costs.

We’re used to a lot of different natural things falling out of the sky. These can include snow, rain and sometimes even frogs (yes, really). All of these relate to weather phenomena.

There’s a question at the heart of SETI that doesn’t get nearly enough attention. It isn’t whether aliens exist, and it isn’t whether we have the technology to detect them. It’s a far more practical problem: With a billion stars in our galaxy and finite telescope time, how do you decide which ones to actually […]
The space between stars may seem like a barren desert, but over the past few decades scientists have been finding all sorts of interesting chemicals in it. From the precursors to proteins to the building blocks of cell membranes, there has been discovery after discovery of new molecules in the giant gas clouds between the […]
Astronomers have discovered a “galaxy-killing wind” that may explain why there are far more massive “dead” galaxies than expected in the early universe. This wind, powered by cosmic collisions between galaxies, could quickly blow away all the fuel for new stars, leaving a galaxy on the brink of death and helping to solve one of […]
Italian astronaut Luca Parmitano is hoping to bring a taste of his homeland to the Artemis III mission, which he will pilot near Earth in 2027 to test two lunar modules.

Astronomers have revealed distinct differences in atmospheric conditions between the morning and evening transition zones of the ultra-hot gas planet WASP-121 b, which separate day from night, commonly called terminators. This achievement was only possible due to the unmatched sensitivity of the James Webb Space Telescope (JWST).
