C’est la hauteur d’une pyramide formée par toute la glace fondue depuis 2011.
(pyramide à base carrée dont les côtés égalent la hauteur).

C'est ~3 fois la hauteur du mont Everest.

Our Large Hadron Collider results hint at undiscovered physics The behaviour of sub-atomic particles in the LHC seems to disagree with the Standard Model.

Only 12 people on Earth saw this 'ring-of-fire' eclipse. Here's how one improvised to capture a once-in-a-lifetime photo from Antarctica A remote Antarctic research team became the only people on Earth to witness a rare annular solar eclipse — and one scientist had to improvise to capture it.

Good work! Shows nicely that ONLY the zodiacal light is responsible for the 'glow' behind the Moon with no contribution from the K corona. (Told you so, NASA, from day one.)

This rather creepy photo is Artemis II’s heat shield underwater, as taken by the U.S. Navy. This is the first photo we have of the heat shield, and upon initial examination it doesn’t seem to have the char loss that Artemis I’s had.

Rubin bags 11,000 new asteroids! This is just the beginning, too. There are more millions more out there waiting to be seen.

The Vera Rubin observatory has already discovered 11,000 *previously unknown* asteroids... and the proper observing sessions haven't even begun yet!

The Earth and the Moon aren't the only interesting things in this photograph, taken 54 years ago today - April 20, 1972.
Apollo 16's Charlie Duke and John Young were in the Lunar Module when Charlie captured this wonderful shot. Ken Mattingly is in the other spacecraft seen orbiting the Moon.

Helle Fassaden nicht das Hauptproblem der #Lichtverschmutzung:
problematischer:
-große Werbeflächen/beleuchtete Schriftzüge (Werbewand Pragsattel/ beleuchtete Schriftzüge an Firmengebäuden)
-helles, blaues Licht an Tankstellen
paradox: Straßenbeleuchtung ausgeschaltet, aber grelle Werbung erlaubt.

I’ve fired one of America’s most powerful lasers – here’s what a shot day looks like It would take hours to set up the perfect shot at the Texas Petawatt Laser facility. Once it fired, the beam released an incredible amount of energy.

Dunkelblauer Himmel mit der sehr hellen, überbelichteten Mondsichel und dem Mond mit aschgrauen Licht. Rechts darunter die hellsten Sterne der Plejaden.

Mond und die Plejaden am 19. April. Ganz klar war der Himmel nicht, wie man sieht.

Die überbelichtete zunehmende schmale Mondsichel mit aschfahlem Mondlicht, darunter die hellsten Sterne der Plejaden am dunkelblauen Dämmerungshimmel

Ihr seht gerade die schmale Mondsichel am Westhimmel? Es lohnt sich, mit einem Fernglas hinzuschauen, sie steht nämlich direkt oberhalb der Plejaden! 🔭

The comet of the hour, C/2025 R Pan-STARRS reached perihelion today at ~7:00 UT/3:00AM EDT, 0.499 AU(46.4 million mi) from the Sun , just exterior to the orbit of Mercury. Currently shining at magnitude +4, dedicated astros are still managing to nab the comet before it’s engulfed in the Sun’s glare.

Astronomie in der Klimakrise YouTube video by Haus der Astronomie

Die Klimakrise ist eine der größten Herausforderungen unserer Zeit. Zusammen mit Andrea Gokus schauen wir uns morgen um 19 Uhr bei Astro & Co live genauer an, welche Rolle die Astronomie dabei spielt - sei es durch negative Folgen oder als Verursacher 🔭

Ask Ethan: How long does it take planets to form? Every time a new star forms, there's an opportunity to form planets alongside and around it. How does it happen, and how long does it take?

Ask Ethan: How long does it take planets to form?

Just 35 years ago, we knew so little about how planets formed, or how long the process took.

Here in 2026, we now have a complete end-to-end story: validated by actual data.

Orbital view of a cloud formation over the icy north polar cap of Mars. The main cloud formation sits in the lower part of the ice cap and appears bright white, shifting to a slightly dustier tone closer to the ice cap. It resembles cirrus like clouds, formed in patches and curved bands shaped by wind. The polar cap below shows a spiral like structure, bordered by rust colored terrain with a faint hazy appearance.

CNSA’s Tianwen-1 mission has recently released new images of Mars, including this view of the north polar cap showing a very cool cloud formation.

#OTD in 1970, the Apollo 13 crew got their first glimpse of the damage caused by the explosion that occurred 200,000 miles from Earth.
The recent Artemis II mission helps us comprehend the gravity of the situation. NASA got the crew home alive.

Here's my photographic analysis of the damage:
