Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new study, repeated lines, notches, dots, and crosses exhibit the same level of complexity and information density as proto-cuneiform script, which emerged around 3000 BC

Die DB vergisst zu oft, dass sie durch Komplettsprrrungen einen weiteren Nagel in ihren Sarg als zuverlässiges und verlässliches Verkehrsmittel haut. Viele Pendler im Nahverkehr und im Fernverkehr sind "alternativlos" auf die Bahn angewiesen. Ein ausgedünnter Minimum-Fahrplan ist immer nötig.

Neue deutsche Aussenpolitik: Wie Merz Europa unabhängig von den USA machen will
Der deutsche Kanzler verspricht, Europa mit einem «prinzipienfesten Realismus» aus der amerikanischen Abhängigkeit zu führen. Doch zwischen Anspruch und Wirklichkeit klafft eine grosse Lücke.

I don't think I've seen this camera angle from an Ariane 6 launch yet. It's cool to see one side of the flame trench in action. Video credit: ESA / ArianeGroup / Arianespace / CNES

'There are so many bones everywhere': The whale graveyards that transform the deep sea
A photographer captured this extraordinary site where whales' bodies lie in the shallows, with troubling repercussions for the deep oceans.
@kathlanpher.bsky.social has written a great article for the BBC about a photography expedition to film at a shallow #whale graveyard near Tasiilaq, Greenland. There are around 20 #minkewhale skeletons here, 15 feet belöw the pack ice

Why Donald Trump gambled in Iran
The disruptor-in-chief wants to send a message to enemies everywhere by demonstrating the devastating nature of American power
Iran fits into a new and broad pattern in which America asserts power. Donald Trump is hurtling towards the future, gleefully flouting the international norms and laws that bound his predecessors

Insane planetary formation over Great Pyramids of Giza.
Mercury, Venus, Saturn, Mars, Uranus and Neptune.
Uranus and Neptune are very dim and were hardly visible to naked eye. They were recorded by long exposure and then added to the image.

Schluss in der MHP Arena.
Ein nahezu perfekter Sonntagnachmittag für den VfB mit dem sechsten ungeschlagenen Heimspiel in Folge. Wir gewinnen hochverdient mit 4:0 gegen die Gäste vom VfL Wolfsburg.
Starke Leitung, Männer!

Norbert Röttgen, stellv. Fraktionsvorsitzender CDU/CSU, mit einer Einschätzung zum Machtgefüge in Iran
Falls die Militäroperation das Terrorregime der Mullahs beseitigt, stellt sich die Frage nach einem politischen Übergang möglichst ohne Gewalt. Nach fast 50 Jahren Unterdrückung gibt es kaum Oppositionsstrukturen im Iran. 1/2

Here is the Pinwheel Galaxy using a 135mm telescope and an Optolong L-Quad Enhance filter. I spent a lot of time (19 hours) gathering data because I have a lot of light pollution but it came out really well!

Visiting a Legend - Opel POST
Donald J. Kutyna explains, how the GT provided a clue in understanding the Challenger catastrophe
Indeed, according to Gen. Kutyna (fellow Rogers commission member) she informed him on the O-ring issue from within NASA sources. To protect her, Kutyna planted the idea in Richard Feynman, the physics legend also serving on the board by using his sports car.

I'm still going through some old images that I wanted to include Chandra data for but have only recently learned how. Look here for N49 without x-rays. This time I opted for blue-green to represent x-rays because magenta was already a prominent color in the optical image. It's harder to conflate the two this way.
I will also simply reference this excellent article which more than adequately explains why this object is interesting to view in high energy wavelengths:

Entanglement-assisted non-local optical interferometry in a quantum network - Nature
Entangled quantum memories are used in a quantum network of silicon–vacancy centres in diamond nanocavities to experimentally perform non-local phase measurements.
Researchers demonstrated entanglement-assisted non-local optical interferometry in a quantum network, using shared entangled photons to link distant interferometers. This enhances precision sensing and coordination across quantum communication links.
