The Sun’s outer atmosphere—the corona—is the piping hot outer limit of our star, and is usually hidden from view except during rare total eclipses. Now, scientists have gotten their clearest look ever at this mysterious region, thanks to a new adaptive optics system that scrubs away atmospheric blur, revealing fine views of the wispy plasma on the star’s surface. Researchers from the National Solar Observatory and New Jersey Institute of Technology unveiled the system today, along with dazzling

Why it matters: Chinese researchers hit a significant data-transfer milestone by transmitting data at one terabit per second over 1,200 kilometers of optical fiber, with encryption embedded directly into the light signal. This approach eliminates any added layers of software-based security – something the global telecom industry has struggled to achieve for years. The breakthrough – developed by Professor Lilin Yi at Shanghai Jiao Tong University – is called the Integrated Encryption and Commun

What just happened? Kioxia has completed the development of its next-gen optical PCIe 5.0 SSDs, which can operate up to 40 meters from the host system without losing throughput. The breakthrough comes from replacing traditional copper connections with optical communication, allowing the SSD to link directly to a server or CPU over long distances. The optical link supports much longer cable lengths and preserves the full multi-gigabyte-per-second speeds of PCIe 5.0. Kioxia has confirmed successf

A Multiwavelength Look at Proxima Centauri’s Flares The problem of flares in red dwarf planetary systems is stark. With their habitable zones relatively near to the star, planets that might support life are exposed to huge outbursts of particles and radiation that can strip their atmospheres. We can see that in nearby M-dwarfs like Proxima Centauri, which is extremely active not only in visible light but also in radio and millimeter wavelengths. New work at the Atacama Large Millimeter/submilli

Subsea fibre cables can 'listen out' for sabotage 3 hours ago Share Save Chris Baraniuk Technology Reporter Share Save Getty Images Subsea cables are critical to the operation of the internet The diver had found the fibre optic cable lying on the seabed of the North Sea. He swam closer, until it was near enough to touch. He reached out his hand. But someone could tell he was lurking there. Someone was watching. "He stops and just touches the cable lightly, you clearly see the signal," says Da
