The Vera C. Rubin Observatory is ready to transform our understanding of the cosmos The telescope will catalogue billions of new objects and produce a new map of the entire night sky every three days with the largest digital camera ever made.

“I can’t think of an astronomer who is not excited about [Rubin],” says Christian Aganze, a galactic archeologist at Stanford University in California.

For Maths fans, 2025 is a square.
45² = 45 x 45 = 2025
Also,
9² x 5² = 2025
40² + 20² + 5² = 2025
My favourite?
1³+2³+3³+4³+5³+6³+7³+8³+9³ = 2025

Finland Seizes Tanker Linked to Russia After More Undersea Baltic Cables Cut Finnish leaders are calling for more NATO protection against alleged sabotage of critical infrastructure by Moscow.

So: In einem nächtlichen Einsatz sprangen schwer bewaffnete finnische Elitetruppen aus Hubschraubern auf einen Tanker der russischen Schattenflotte ab und kaperten das Schiff, das mehrere Unterseekabel in der Ostsee durchtrennt hatte. www.wsj.com/world/europe...

And now, I will take you
to one of the bookstores in Kyiv.

I want you to see how beautiful
Kyiv is.

Attention, Estonia!

Russian propagandist Keosayan:

"What are they going to protect? Their 10 Estonian acres? I have two options for what happens after 2028. Either Estonia will be safe within the Russian Federation, or Estonia will no longer exist."

"We are like butterflies who flutter for a day and think it's forever."

В Вологде открыли памятник Сталину За несколько часов до этого губернатор Филимонов возложил цветы к мемориалу жертв политических репрессий

Ein weiteres Stalin-Denkmal in Russland, aber es gibt Leute, die sagen, die Ukrainer könnten unter russischer Besatzung in 'Frieden und Sicherheit' leben. Bis 2023 wurden 110 Denkmäler errichtet, 95 unter Putin. Seit der Krim-Annektion hat sich das Tempo verdopplt.

Tonight Gáttaþefur (Doorway Sniffer), the 11th of Iceland's 13 Yule Lads, comes down from the mountains. He has a very long nose and a keen sense of smell, which he uses to find laufabrauð.

Children leave their shoes out in the window, he gives the good ones a small gift, the bad ones get a potato.

After Putin's humiliating press conference, Putin throws a temper tantrum, launching several ballistic missiles onto the people of Kyiv at 7am, 5 days before Christmas.

Ich denke an all meine Mandant*innen, die Opfer sexualisierter Gewalt mit KO-Tropfen geworden sind und deren Verfahren fast alle eingestellt wurden. Auch, weil es die Ermittlungsbehörden eigentlich nie für erforderlich erachten, die Handys der Beschuldigten zu durchsuchen. #Frauenhass

Kyiv this morning after missile attack: 8 missiles, including ballistic Kinzhal and Iskander types. Sickening creatures

Russian soldiers film themselves robbing apartments in the occupied city of Selydove, Donetsk region.

It seems they are enjoying it.

Disgusting.

What Christmas time looked like in Ukraine before the Russians came. This is the Rozhanytsya Folk Ensemble.

Thanks @sofiaukraini.bsky.social !

Anapa may have to forget about being called a "resort city" for a long time.

The storm is bringing more and more petroleum products from tankers that sank in the Kerch Strait to Anapa's beaches. The oil slick has already contaminated up to 35 km of coastline.

We are asking Ukrainians to defeat the armies of Putin and Kim Jong Un. In their efforts to do so, Ukrainians helped bring down Assad. Ukrainian resistance is one of the most stunning military achievements in modern history.

"i am not at war with the Ukrainian people"

Satellite images of mass graves outside Mariupol. 10s & 10s of thousands.

Another environmental catastrophe caused by Russians east of Crimea, after one of their decaying oil tankers broke apart on high seas 2 days ago, 35km of pristine coastline has been contaminated in true Russian style.

And these tankers are now all over the world.

Syrian army fighters have captured the strategic T4 airbase in Syria, driving out the Russians with curses.

According to Arab and Western sources, there is a partial withdrawal of Russian units.

In einer bemerkenswerten ersten großen Rede sagt NATO-GS Mark Rutte: “Die Sicherheitslage ist die schlechteste in meiner Lebenszeit.” Er hat recht. Trotzdem machen wir in Europa weiter mit allem wie immer, statt erst einmal Sicherheit zu schaffen.

Some cartoons aren't meant to be funny. 💔

Weil wir so ein gutes Langzeitgedächtnis haben, hier ein Beispiel, mit wem wir es in Russland im Jahr 2024 zu tun haben.

Hat jemand dagegen offene Briefe geschrieben und Unterschriften gesammelt? Irgendein Promi-Sänger eventuell dagegen was gesagt?

Nein? Dachte ich mir. 🤨🤷‍♂️

Many people were swayed by russian propaganda that placed blame on NATO for russia's invasion of Ukraine. However, the reality is far more straightforward: russia remains what it has always been.
