20 Jan 2026 G4 Aurora. Cape Tourville, Tasmania. The aurora was very colourful in camera, with a mix of reds, greens, purples and blues. Not very colourful naked eye, though.

Remembering Gladys West: who used Einstein to create GPS

RIP to Gladys West: the "hidden figure" most people have never heard of, but whose work is second only to Einstein's in enabling and developing our modern GPS.

Castle Mountain, Banff National Park, Alberta, Canada. Pure beauty. I found a small puddle to capture the reflection of a frosty Castle Mountain in early morning twilight.

Was soll man nun machen aus diesem rülpsenden Auftritt von Trump in Davos, seinen Verdrehungen und Drohungen (für die es gleichwohl Standing Ovations der Wirtschafts-„Elite“ gab), seinen chaotischen Positionswechsel und seiner Kehrtwende (???) bei Grönland? Die NYT fasst das Wichtige gut zusammen.

How a solar radiation storm created January 2026’s aurora

The first good auroral show of 2026 began not with a solar flare nor a coronal mass ejection, but a solar radiation (particle) storm.

It's the first big one since 2003!

How a solar radiation storm created January 2026's aurora
The Sun often produces solar flares and coronal mass ejections, but a rare solar radiation storm made the 2026's first great auroral show.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.
