French astronaut Sophie Adenot has shared images and video from one of the strongest aurora displays she has seen during her time aboard the International Space Station. The capture dates to day 127 of her εpsilon mission, logged as orbit 1968, and she called it the most spectacular one yet.
A visit by iFixit to one of China’s large battery production sites offers a rare look at how replacement batteries for iPhones actually get finished and tested. The team captured the work on video, showing lead teardown technician Shahram Mokhtari walking through the final assembly steps that turn a bare lithium-polymer cell into a complete, safe pack ready for installation.
Fitness trackers flood the market with options that range from stripped-down counters to full smartwatches loaded with apps and sensors. Many buyers end up frustrated when a device either skips the basics or piles on features that demand constant charging and attention. The Fitbit Charge 6, priced at $76 (was $160), takes a different path by sharpening the core jobs most people actually want from a wristband while adding just enough extras to feel modern and useful.
Custom engineering packs an entire independent technology system into one portable case. Urban Circles shared this project, often referred to as the ATU or off-grid tech kit, to show how everyday devices can combine into something that keeps running when power and internet disappear for days at a time.
Right before crowds across the country prepare to mark the Fourth of July with displays of light and sound, NASA’s James Webb Space Telescope offered a view from far beyond Earth that carries a similar sense of energy and new activity. Two protostars in the FS Tau system sit near the center of the frame. Both remain young enough that they still draw in gas and dust while pushing excess material outward through strong flows.
