NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of a mid-level solar flare on Jan. 12, 2015.

That’s more …

Eufy just introduced its latest outdoor security camera at IFA in Germany. The EufyCam S4 monitors your home using a fixed 4K wide-angle camera and a pair of 2K sensors that activate when a possible intruder is spotted and track them. Capable of auto-framing its subject, the main camera can pan, tilt and zoom in on a person as far …

A Concorde was once used to study a solar eclipse in a way no ground-based observer could match. Normally, the longest a total eclipse can be seen from one point on Earth is just over seven minutes. But in 1973, scientists extended that window more than tenfold by chasing the Moon’s shadow across Africa at supersonic speed. For 74 extraordinary …

Solar eclipse maps show crisp lines for the path of totality, the narrow strip where a total solar eclipse will be visible. But in reality, the edges of the path are fuzzy, jagged and sometimes wrong by hundreds of meters or more. That might not matter if you’re standing on the path’s centerline, where many eclipse chasers head to experience …

Solar flares are the Sun at full volume – sudden bursts of magnetic energy that can supercharge Earth’s upper atmosphere, disrupt radio signals, and threaten satellites and astronauts.  For decades, physicists have known that flare plasma gets incredibly hot, but exactly how different particles heat up – and why certain spectral fingerprints look “too wide” to explain – has remained …

IN A NUTSHELL 🌿 Researchers at the University of Basel have developed a molecule essential for artificial photosynthesis. 🔋 The molecule can store two positive and two negative charges simultaneously, a critical advancement in energy storage. ☀️ The process mimics natural photosynthesis to produce carbon-neutral solar fuels like hydrogen and methanol. 🔬 This research provides insights into electron transfer mechanisms, …

Credit: NASA/JPL-Caltech; image of 2017 OF201: Sihao Cheng et al. A new trans-Neptunian object, 2017 OF201, has been found with a vast orbit and potential dwarf planet size. The finding hints at more hidden bodies beyond Neptune. A …

Scientists studying samples from the asteroid Bennu have found that it contains a remarkable mix of materials — some of which formed long before the sun even existed. Taken together, the findings, described in a trio of recently published papers, show how Bennu has preserved clues about the earliest days of our solar system. “It’s very fascinating to see that …

A powerful solar flare is set to unleash a geomagnetic storm tonight, potentially pushing the aurora borealis far enough south to spill into northern Oregon, lighting up skies throughout the Pacific Northwest. NOAA’s Space Weather Prediction Center has issued a G2 (moderate) to G3 (strong) geomagnetic storm watch for Monday and Tuesday nights, with a chance the storm could briefly …
