Planes grounded after #Airbus discovers #SolarRadiation could impact #systems

Theo Leggett and Yang Tian, BBC News, December 5, 2025

Excerpt: "Airbus discovered that, at high altitudes, its data could be corrupted by intense radiation released periodically by the Sun.

"That led to the October incident in which an aircraft suddenly lost altitude - though the manufacturer said this was the only time an incident of its kind had occurred."

Flights disrupted after Airbus discovers intense sun radiation could impact flight control data

The issue is thought to affect 6,000 planes, which will need to undergo an urgent software update or have computers replaced.

#Chitonida (#Mollusca) exist since the #Cambrian. Bodies are covered with #calcareous #plates, flexibly connected. Most feed on vegetation cover. The #CambrianExplosion made based i.a. on #oxygen significant leaps in #animalevolution. Y. Zhang et al. (2025) assume a change in Earth's orbit altering #solarradiation, leading to land #weathering and #nutrients flow to the sea. Algae thrived and produced much oxygen.

Did you know Earth's magnetic field isn't just constant? It drifts and even FLIPS over time! 🌍⚡ This 'geomagnetic reversal' has happened many times—last 780,000 years ago. When poles swap, the field weakens, exposing us to extra radiation. Could we be due for another flip? The field is weakening now, sparking urgent research! #EarthScience #GeomagneticReversal #MagneticField #SolarRadiation #PlanetEarth #NatureMysteries (1/1)

A simple approach to measuring upper ocean light quality using an underwater camera

Solar radiation is the fundamental driving force of the Earth’s system. In the upper water column, interactions such as absorption and scattering by water constituents decrease light intensity (photon quantity) and alter light quality (spectral distribution of photons). Although changes in solar intensity have been extensively studied over the years, variations in light quality with depth have received comparatively little scholarly attention. This dearth of research may be due to the lack of simple and cost-effective instruments for measuring light quality, unlike commercial instruments available for measuring solar intensity. In this study, we present a simple approach that uses an underwater camera and a diffuser to measure light quality, represented by the hue angle (HA) of the downwelling irradiance. Our results reveal that the HA from this simple, low-cost device aligns closely with measurements from an expensive hyperspectral radiometer across various water types, ranging from oceanic to coastal waters ( R 2 = 0.94, mean absolute percentage difference = 1.64%). The widespread adoption of this approach could significantly enhance our understanding of the impact of solar radiation on the biogeochemical processes in aquatic environments.
