W.T.A.F? 🤡 straight out of the Dark Ages. No surprise they started a war against logic and science.

Τα τελευταία 2 χρόνια συμβαίνουν απίστευτες συμπτώσεις στη ζούγκλα Μητσοτάκη: -Κώστας Χρυσάγης, Διευθυντής κυκλοφορίας του ΟΣΕ (νεκρός) -Κώστας Πρασσάς, Σταθμάρχης του ΟΣΕ (νεκρός) -Βασίλης Καλογήρου, γιος της εισαγγελέως (προϊσταμένη Μπαικάμη) που ερευνούσε το έγκλημα στα Τέμπη…
Whoever is a scientist, should sign this.
Space scientists have put together an open group letter (sites.google.com/view/space-sci…): "To NASA leadership and our elected representatives: We write as members of the space science community who are dismayed by the impact of recent events on taxpayer-funded, NASA-supported science,…
In this very beautiful capture, we see a 22 deg. halo, both 22 deg. parhelia (or sundogs) and an upper tangent arc on top. No circumhorizontal arc here (the sun is too low anyway and the only thing one could possibly see is a circumzenithal arc high in the sky)
Help needed. This evening I’ve been flying over Africa, Ghana in fact. In the night sky, to the west, was this weird shaft of light…surrounded by what looked like aurora. It was there for about 90 mins. Can anyone assist in identifying what it is? It’s not smoke before that’s…
Awesome video of "steam devils" on Lake Superior. Warm + moist below, cold above. In this environment, some random whirls of wind "grow up" to become weak "tornadoes" made of steam.
The tail of #comet C/2024 G3 #ATLAS after sunset! Also observe the #zodiacal light extending through #Venus and #Saturn 🤩
This is the best we can hope for, from ATLAS comet, during twilight on the next few days, here in the northern hemisphere
Tail of ATLAS from Maunakea (HP), Hawai'i !! ついにアトラス彗星（C/2024 G3）の尾を捉えました！ 頭部は既に沈み、尾だけが夕焼けの光にヴェールの様に見えてます。 複雑な構造が何となくわかります。すごい！ Nikon D5100 85mm F4.5 10秒露出 ISO3200 を８枚合成 2025-01-18 (HST) 19:17~
Impressive shot as always from Yuri!
🚨 Comet C/2024 G3 (ATLAS) is ablaze !! I can hardly believe the spectacle we're witnessing, and it's only improving 🤯 I captured this image on January 18 during twilight at the ESO Paranal Observatory in the Atacama Desert, Chile. The comet sets later each night, offering…
That's an awesome capture! ⚡️
Screen grab from the drone video with one of the many #lightning strikes that were landing over by Robertson Barracks ⚡️ #drone #TopEnd #storms #StormHour
Mt. Parnitha, north of Athens, last night, -1 deg. and fog. Fogbow, Brocken spectre, glory and a taste of snow #StormHour @StormHour
Daytime photo of comet ATLAS. Superb!
１月13日、日の出直後のアトラス彗星。モノクロで撮影したものを着色しました。太陽離角が小さいので、太陽が隣家の屋根で隠れているうちに撮影しました。尾をもっとあぶり出したかったのですが、これ以上は背景がノイジーになってしまうので、ほどほどに…。 ＃Cometobservation #彗星観察…
Almost not visible from N. Hemisphere (very very close to the Sun). Maybe, if its tail gets long enough, one will see it setting after the sun a few days after perihelion (13 Jan)
It is totally amazing to see a comet from orbit. Atlas C2024-G3 is paying us a visit.
A while ago over Athens. 22 deg halo, supralateral arc, circumzenithal arc and faint upper tangent arc. #StormHour @StormHour
This is the next generation. A very promising (and tested) energy proposal which will easily fill the gap between available and needed energy and will take us safely to the next step whenever that will be ready: Fusion.
The importance of instant communication. A friend was the 1st to see #AuroraBorealis on 01.01.2025 at NW Greece & he immediately pm me. I shared the info directly & now we have at least 12 observers. This is the updated map. I’ve gathered photos, etc here: antisimvatikos.blogspot.com/2025/01/blog-p…
