A black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing. Using a chain of atoms in single file to simulate the event horizon of a black hole, a team of physicists in 2022 observed the equivalent of what we call Hawking radiation – particles born from disturbances in the …

Images of interstellar comet 3I/ATLAS snapped during the September 7 total lunar eclipse seem to suggest that the latest visitor to the Solar System may be turning green. That’s not all that strange for a comet. Many Solar System comets give off a green glow when they heat up enough to emit vapor. However, for 3I/ATLAS, it might be quite …

Mars may be known as the Red Planet, but under the right cosmic conditions, its skies shimmer emerald with auroras — and for the first time, scientists think they can predict the spectacle. Being able to predict Martian auroras, which result from solar storms that also unleash harmful radiation, could provide future astronauts with crucial warning and time to take …

Here’s an image of the new Comet SWAN25B. Michael Matiazzo captured this image on September 14, 2025. It shows an impressive, 2.5-degree-long tail, which translates to about 5 full-moon diameters long! The bright star in the upper left of the image is Spica. The comet will pass close to that star around September 15-16. New Comet SWAN25B soars into the …

The brightness contours feature an elongation of scattered sunlight towards the Sun and not away from it as previously observed for solar system comets. The yellow and green arrows mark, respectively, the projected negative heliocentric velocity vector …

‘The Wizard of Oz’ Is Getting an A.I. Glow Up. Cue the Pitchforks.  The New York Times How do you make ‘Wizard of Oz’ work at the Sphere?

Since the early 2000s, scientists have been puzzled by a gleaming turquoise spot in the middle of the Antarctic Ocean showing up in satellite images. The patch is located just south of the great calcite belt, a region that’s rich in the mineral form of calcium carbonate, and teeming with coccolithophores, tiny marine organisms that grow reflective calcite shells out …

A beaming patch of turquoise amidst the Southern Ocean’s blue-grey waters that’s baffled scientists ever since it was first spotted in satellite images in the early 2000s may have finally been deciphered by oceanographers. Mapping concentrations of phytoplankton and biogeochemical compounds has revealed a curious combination of microorganisms that challenges assumptions about the way the frigid waters of the world’s …
