The magnificent Orion constellation is always easy to find and beautiful to look at in the night sky.

I’m awake in that late-early hour when thoughts are blown thru unguarded gaps by a heavy, uneven winter wind outside. Dark and wind lay things out and persuade me to look.
Nothing is wrong, exactly. But not everything is settled, either—especially at this hour.

I think every advance in technology lowers our quality of life.
Before the phonograph was invented, most households had a place where family members would get together and play music. When the phonograph arrived, you could hear the best in the world, and how could you compete with the best?
Looks like a very old man.
The future of the world is being shaped in Europe, says German Chancellor Friedrich Merz
...this still assumes deposits of economic value exist in the US.

Currently performing SEM on zinc anodes 🔬. It looks pretty, but one of the major issues with rechargeable zinc #batteries apart from hydrogen evolution is the formation of dendrites, which lead to capacity loss and ultimately short circuit the cell🪫.
As a matter of fact, Ag is an important byproduct in many lead mines and sometimes, galena is mined mainly for the high Ag content in it. Ag may occur as solid solution or as inclusion of other Ag-bearing minerals in the galena.
Great, it looks so easy.
Remember, Galena is not only the principal ore for lead, but also an important ore for silver. Vote Galena.
Shatter cones in a recently discovered Precambrian impact site near Santa Fe, New Mexico. Shatter cones are the result of shock waves generated by the energy of a point source impact. These shockwaves radiate outwards from the point of impact, fracturing rock along the way.
I wonder, aren’t the BIF‘s rather confined to the Fig Tree Geoup ?
From where is it ?

A M7.4 earthquake struck the Philippine subduction zone today, causing damaging shaking across much of Mindanao. Several people have died.
This is the Philippines' second deadly earthquake in two weeks. Are the events related? And how does this quake compare to the nearby M7.6 in 2023?

Made this figure for a book chapter on tectonic reconstructions that I'm writing with Jonny Wu, using a fantastic field photograph of Joao C. Duarte, of the Telheiro Beach section in SW Portugal.

The last one, with the garnets, is this an eclogite?
This is great, BUT the year we burned the most coal was 2024 and it's still going up.
A young woman with glasses sits on a wooden bench outdoors, smiling at the camera while holding a viola on her lap. She is wearing a black top, wide green pants, and black heeled sandals. On the left side of the image, there is a large colorful speech bubble with the following quote: “I primarily focused on the symbiosis between fungi and endosymbiotic bacteria. We identified natural products produced by the bacteria that protect the fungi from predators and play a key role in the symbiotic relationship.” At the bottom left, the “Leibniz-HKI” logo is visible. At the bottom right, a large purple arrow points to the right.
A graphic calendar page with a turquoise-blue gradient background. In large pink letters it says “SEPTEMBER,” and underneath: “Hannah Büttner.” At the lower left is the “Leibniz-HKI” logo with the text “Leibniz-HKI Calendar 2025.” At the lower right, the word “SWIPE” is written in bold black letters next to a large purple arrow pointing to the right.
A young woman in a white lab coat is working in a laboratory. She is holding a pipette and placing a sample into a scientific instrument. On the right side of the image, there is a speech bubble in a turquoise color gradient with the text: “I particularly enjoyed structural elucidation and analytical challenges.” Below, the logo of LEIBNIZ-HKI is visible. A large purple arrow points to the right.
A young woman with glasses, wearing a black t-shirt and green trousers, stands indoors next to a large aquarium full of fish and aquatic plants. She holds a viola under her arm and looks thoughtfully into the distance. Her reflection is visible in the aquarium glass. Colorful text bubbles on the right side of the image read: “I like it when Art and Nature come together.” The words “Art” and “Nature” are highlighted in bright, decorative fonts. At the bottom left corner, the logo “LEIBNIZ HKI” is visible.

#Carpathite is composed of hydrothermally deposited coronene. Coronene is also proxy for wildfire activity, a function of terrestrial biomass, atmospheric O2, and ignition sources like lightning, volcanoes, and bolides. The oldest known occurrence on Earth dates to the early Ediacarian.

⚒️ 🧪 Another big addition to the remarkable M8.8 earthquake sequence offshore Kamchatka: a M7.8 - the biggest aftershock so far.
With foreshocks, aftershocks, aftershocks of foreshocks, and foreshocks of aftershocks, it's hard to keep these earthquakes straight! Read more about what's going on:
