*2026 El Niño Ahead by a Mile* It’s remarkable for us scientists to witness El Niño’s evolution. If you had asked us if something like this was possible a year ago, it would have been a definitive no. But here we are… already more than 1C (& 3 months) ahead of the next strongest episode in 1997… 1/

No Kaboom spotted. Now everyone interested in astronomy is waiting to see if the Lunar Reconnaissance Orbiter may have spotted. Follow @nasaupdates.bsky.social or @eso.org for more info.

"Well you can't win them all on astronomy events" Heroic efforts by all the live-streamers on YT! Sad that there was nothing visible to see, but here's hoping @eso.org detected something. We wait with excitement for the Lunar Reconnaissance Orbiter images of the moon's new crater! 🔭

Even if this image is unfinished in it's processing it is still beautiful. To me it looks like the hand of God reaching out.

I've learned I need a better computer if I'm going to continue to process JWST raw data. 6 hours into processing the Pillars of Creation yesterday, I ran a star removal script that crashed the program, all progress was lost. My fault for checking email.😬 Starting again, image is before the crash.🔭

The image is of green hued dense clouds of interstellar dust with 3 large columns projecting upwards. They're against a background of blue/black space with bright stars all around Crefits: • Raw Data: NASA, ESA, CSA, STScI • Data Source: Mikulski Archive for Space Telescopes (MAST) • Observation Program: JWST Program ID 2731 (PI: Klaus Pontoppidan) • Wavelengths Used: NIRCam F090W (Blue), F200W (Green), F444W (Red), F187N (Green/Cyan), F335M (Yellow/Orange) , F444W-F470N (Orange/Red) • Image Processing: @lesiadub.bsky.social

Got my water and buttons ready for the Voter Registration drive in Rogers this Saturday. The weather even looks like it will cooperate with a lower temperature. Should be a good day. Register - Prepare - Vote !

Tiny mammoth ivory bird figurines found at Hohle Fels cave – The History Blog

Personally, I love the carved lions and snow leopards (from a different cave, I suppose). Confusingly, the ‘Hohler Fels’ cave, e.g., is not to be confused with the ‘Hohlen stein’ cave 😉

WOW, new finds from the Ice Age! Two absolutely stunning Ice Age figurines from the Swabian Jura were found, dating back around 40,000 years. The tiny carvings, about the size of a thumbnail, depict two birds, rendered with remarkable attention to detail. Snow grouse, buzzard, or...🧵1/2

Time to start collecting your seeds for your fall garden ...

🌱🌾🌍🌺🍄🌳🌲🌿🍃🖌🐡 Seed germination. Nothing appears to happen but seed has has signal good time to germinate, lets water in, furious production new proteins, uses stored food. Root emerges, starts working, then shoot pushes up through soil into light. Leaves form, unfold, start photosynthesis #BUC2026

Diagrams of seed germination in Fabaceae. Germination has the following steps: Step 1: The dry seed remains dormant before germination begins. The seed coat protects the embryo inside. Step 2: Signals for germination received and acted upon. The seed absorbs water through imbibition, causing the seed coat to soften and swell as the embryo becomes active. Step 3: Continued water absorption prepares the embryo for growth and development. Extensive new proteins produced and stored food (within cotyledons in this family) used. Seed coat ruptures. Step 4: The radicle (first root) emerges first from the seed coat and begins growing downward to absorb water and nutrients. Step 5: The plumule begins to emerge and grow upward as the plant starts developing. Step 6: The root system expands and the cotyledons begin to grow. Step 7: The shoot continues upward growth as the hypocotyl elongates and lifts the cotyledons above the soil surface. Must be achieved before all stored resources consumed. The young seedling begins developing its first structures for continued growth. Shoot apical meristem becomes active. Step 8: The first true leaves emerge from the epicotyl. The cotyledons provide stored nutrients until the plant can sustain itself independently. Step 9: The first true leaves expand and become the primary site of photosynthesis. The epicotyl continues elongating to support upward growth while the root system develops further for increased water and nutrient absorption. The cotyledons fall off and the young plant is now self-sustaining.

I really like to see dolls and toys that children played with from our ancient past. Shows us things really don't change that much when it comes too being human. @drnwillburger.bsky.social is always a good source & she provides great additional info & sources for further research.

Beloved toy: An over 1800-year-old rag-doll made from linen and stuffed with flexible filling, and dressed in linen garments. The hair is made of human hair. The eyes, eyebrows, and mouth are painted on. The doll is one of the most elaborate of its kind and presumably belonged to a... 🧵1/2

A rag doll made from stitched cloth with a stuffed torso and long sewn legs, dressed in a coarse beige tunic that shows holes and mending. The doll has dark, tousled textile hair; a pale, painted face with simple eyes and mouth; small gold earrings hanging at the sides of the head, wearing a neck ring and bracelets too. The doll is shown upright against a black background.

I had to get up at 6 am this morning to catch the hummingbirds fighting it out for the bird feeder before it got too hot to stay outside. One stinker would hide in the tree to ambush any of its rivals that appeared.
