Astronomers report detecting radio waves that may originate from an exoplanet, potentially the first such detection ever made. If confirmed, the signal would suggest the distant planet has a magnetic field, a property never directly observed on a world outside our solar system. The finding is drawing attention from space and astronomy enthusiasts following coverage by major science outlets, with researchers emphasising that further observations are needed to verify the origin of the emission.

New coverage warns that Earth's magnetic poles could be heading toward another reversal, an event where the planet's north and south magnetic poles swap places. Reports focus on what such a flip could mean for climate, navigation systems, satellite operations and the shielding that protects Earth from solar radiation, though scientists note reversals happen gradually over thousands of years.

New research suggests magnetic fields may have played a key role in the formation of the solar system, potentially influencing how material in the early solar nebula collapsed and clumped into the sun and planets. The finding adds to ongoing debate among scientists about the physical processes that set planetary formation in motion more than 4.5 billion years ago.

A researcher at the University of Central Florida reports experimental evidence of a new type of magnetism, according to a news release.

Researchers report a technique for reshaping light to control magnetic memory and adjust a material's magnetic properties. The advance could point toward faster, more efficient data storage, since it suggests magnetism in certain materials can be manipulated optically rather than only with electric currents or magnetic fields. Details of the method and its practical applications have not been widely reported yet.

Harvard scientists report detecting a radio signal apparently coming directly from a planet outside the solar system. If confirmed, it would be a rare example of a radio emission traced to an exoplanet, possibly generated by the planet's magnetic field interacting with its star. Astronomers say such detections could open a new way to study distant planets, though further observations are needed to verify the signal's origin.

The claim has drawn attention to the ongoing standoff between Apple's device protections and law enforcement's forensic access tools.

The SMILE satellite has ended an 18-year gap in observations of the northern lights, and researchers say new views of Earth's x-ray magnetic shield are just weeks away. The mission is expected to provide fresh insight into how the solar wind interacts with Earth's magnetic field, producing auroras. Space science outlets are highlighting the milestone and the images anticipated in the coming weeks.

JD Vance's speech at Lakeland International Airport's Sun n Fun Expo Center in Florida drew protesters and hecklers who interrupted the event. The disruption came despite what critics describe as heavy security and repression of protesters elsewhere in the United States this year. Attendees and observers shared accounts of the heckling, framing it as a sign of ongoing public anger toward the Trump administration and its policies.

Retailers are running early fall discounts, with the Samsung Galaxy Z Fold 8 cut by up to $546, Belkin magnetic charging stations starting at $43, and TVs marked down by as much as $1,100. The price drops coincide with Amazon's early fall Prime Day sale, and deal trackers are also highlighting discounts on the Moto Tag 2 item tracker.

The Pentagon has invested in a startup that aims to supply metal used in critical magnets, according to a Wall Street Journal report. The move reflects growing US concern over reliance on foreign supply chains for magnet materials, which are essential to weapons systems, electric vehicles and electronics. The investment signals Washington's push to build domestic capacity in strategic minerals.

A new podcast episode presented by pikarl turns to Mercury, the smallest planet in the solar system. The episode describes the planet as a genuine oddity: an unusually high mass for its size, a strong magnetic field and a chemical composition that does not fit existing models. According to the discussion, every space probe sent to Mercury has so far deepened rather than solved its mysteries.

Astronomers report that enigmatic flashes of X-rays in the sky may come from the catastrophic merger of two stars, producing an ultra-dense, ultra-magnetic remnant known as a magnetar. The findings emerged from a collaboration between Chinese and European science missions, and are drawing attention among space researchers and enthusiasts discussing what the discovery reveals about how magnetars form.

The Pentagon has joined a $134 million funding round for a startup working to produce U.S.-made iron for rare-earth magnets, according to a Wall Street Journal exclusive. The investment signals a push to build a domestic supply chain for materials critical to weapons systems, electric vehicles and electronics, reducing reliance on foreign producers, particularly China.

Astrophysicist Franco Vazza has wrapped up an electromagnetism trivia question on Mastodon, revealing that only a tiny fraction of respondents answered correctly. The right answer: Mickey Mouse floats because of magnetic levitation in a variable magnetic field, which Vazza explains in a follow-up post on the physics behind the effect.

Reports say GrayKey, the iPhone extraction tool made by Magnet Forensics and widely used by law enforcement, can circumvent Apple's 'Inactivity Reboot' feature, which was introduced to lock devices against forensic tools after periods of inactivity. The claim, picked up by 9to5Mac, raises fresh questions about the limits of Apple's device security and the tools police can use to access seized iPhones.

The stratospheric research observatory Sunrise-III has returned new observations revealing intricate magnetic structures on the Sun. Flying high above most of Earth's atmosphere, the observatory captured detailed measurements of solar magnetic fields, findings now reported by science outlets and the Japanese astronomical institute NAOJ.
