Gigantic jet TLE above Mexico (crop) - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2rhxUhJ
On July 3rd, astronaut Nichole Ayers photographed a gigantic jet from the ISS. These rare upward directed electrical discharges extend ~90-100 km high into the mesosphere. The jet originated from a thunderstorm over Northern Mexico, with city lights from South Texas and the green airglow layer visible along Earth’s limb. I processed this image from the RAW file, adjusting the color profile, white balance and contrast and applied Lightroom's machine learning denoise with low strength. The RAW was provided to me by Frankie Lucena, his analysis of the event, correlating it to measurements from the Geostationary Lightning mapper and ELF-VLF radio signals can be found here: spaceweathergallery2.com/indiv_upload.php?upload_id=224355 Original image listing in the NASA archive: eol.jsc.nasa.gov/SearchPhotos/photo.pl?mission=ISS073&amp...

Dear Physicists and Physics fans,

I would like to encourage you to celebrate #WomenInPhysics Day this Friday, November 7th.

Why November 7th? Because it is the birthday of two of the most impactful women physicists of the 1900's: Marie Curie and Lise Meitner. 🎢 ⚛️ 🧪 👩‍🔬
WOMEN IN PHYSICS DAY! In honor of the pioneering women in physics who broke down barriers to do what they love, we celebrate Women in Physics Day on November 7th, the birthdate of both Marie Curie and Lise Meitner. Marie Skrodowska-Curie (1867-1934) Radioactivity pioneer, two-time Nobel laureate A giant of science, Marie Sktodowska-Curie conducted pioneering research on radioactivity, a term she coined. She discovered two elements, founded two medical research centres, won two Nobels, and invented mobile X-ray units (dubbed petites Curies), saving countless lives in World War Lise Meitner (1878-1968) Nuclear physicist When Lise Meitner was a teen, Austria restricted female higher education. She pursued physics anyway, and 25 years later became the first woman in Germany to hold a professorship in physics. She helped discover nuclear fission, but was contentiously not awarded the 1944 Nobel alongside collaborator Otto Hahn. NOVEMBER 7TH

Aujourd'hui, c'est le #WorldPastaDay.

L'occasion de rappeler que cette année, le prix IgNobel de physique est revenu à l'équipe italienne responsable de cette passionnante étude sur les transitions de phase de la sauce des pâtes "cacio e pepe".

You gently run your hand through the rack. You can feel it—pure cotton, rich wool, Irish linen. The plump buttonholes are handsewn; the buttons attached with a firm shank. You flip the price tag over. It's affordable

You buy the jacket and go home, which is only 15 mins away. Your apt is $600/month

Light and vegetation can produce a very impressionistic bokeh.

A photo of a marbled white butterfly still roosting with its front wing a bit pushed out and the wings lit by the back light of the sun and shining through them. The bokeh looks swirly of the back light coming through all the wildflowers and vegetation.

I'm still wondering if it's a common blue [Polyommatus icarus] or a Chapman's blue [Polyommatus thersites], but I'm tending to the first one.

A photo of (very likely )common blue butterfly - still roosting on a burnet in front of the rising sun. Through using a long macro lens and open aperture the sun appears as a big orange disc behind the butterfly. The tones in the photo range from violet to orange - on this hazy early morning.

A Fourier transform breaks down a complicated function into a set of frequencies. It’s like sniffing a perfume and determining its list of ingredients.

In 2021, archaeologists announced the discovery of the 3000 year old Egyptian city called "The Dazzling Aten" near Luxor.

I want to call your attention to a brick wall under the red arrow. It's 'serpentine' & a single brick wide, separating a housing complex from the road.

Why the odd shape?
