We live on a planet wrapped in a magnetic shield that waxes and wanes with solar activity. Most days, that quiet background barely draws notice. Some days, it fluctuates more strongly. The study behind this article asked a simple question: when Earth’s magnetic field gets unsettled, as it does during solar storms, is there a direct correlation to the number …

The interstellar object dubbed 3I/ATLAS has been fascinating astronomers since its discovery in early July. The object, generally believed to be a comet, is screaming through the solar system at around 137,000 mph, and is expected to make a close pass of Mars as soon as next week. And it recently met some considerable resistance as well during its unusual …

The National Aeronautics and Space Administration has confirmed an interstellar object is passing through our solar system. The object is a comet hailing from the direction of the constellation Sagittarius, and is only the third of its kind ever seen, according to Live Science. The comet is officially named 3I/ATLAS and is currently about 420 million miles away, according to …

Formamidinium lead iodide is considered one of the best-performing materials in the halide perovskite group, since it has promising properties for future solar cell technologies. New findings from Chalmers can now shed light on its structure; this is crucial if we are to engineer and control the material.

A mysterious object hurtling through space has been identified as a rare “interstellar object,” only the third of its kind ever seen. In July, NASA reported its ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope in Chile identified a comet that originated from interstellar space. Arriving in the direction of the constellation Sagittarius, the comet was dubbed 3I/Atlas. The comet …

The number of confirmed planets outside of our solar system—known as exoplanets—has risen to 6,000, NASA has said. There is huge variety across these distant worlds, the space agency says, with discoveries including rocky planets, lava worlds, and gas giants enveloping their stars. Plenty more discoveries are likely on the way. As a result of continued monitoring by NASA’s Exoplanet …

HANDS ON Logitech is harnessing solar power in the K980 Signature Slim keyboard to solve a problem that might not have occurred to some users: battery anxiety. The full-size keyboard (with a separate number pad) employs solar charging tech called Logi LightCharge, featuring a solar panel along the top of the device and a rechargeable battery within. Logitech reckons that …

SpaceX just sent three space weather probes to the final frontier. A Falcon 9 rocket lifted off from NASA’s Kennedy Space Center in Florida today (Sept. 24) at 7:30 a.m. EDT (1130 GMT), carrying NASA’s IMAP mission and and two other spacecraft. Each probe has its own objectives, but all three will work toward the same larger goal: help scientists …

On Feb. 17, 2026, an annular solar eclipse will be visible from a remote part of Antarctica, forming a “ring of fire” for up to 2 minutes, 20 seconds as 96% of the sun’s center is eclipsed by the moon. Few will witness that moment, but observers in the rest of Antarctica — including those on cruise ships on late-season …
