Men, det kræver man ved hele tiden hvordan lufturoen er lige nu. Det kan man måle ved at have en meget kendt lyskilde, som man kan kalibrere efter. Det kan være en guide stjerne som er meget kendt, eller en falsk stjerne lavet ved at ionisere luft i 50km højde med en kraftig laser 😝

Uh ja. Adaptiv optik. Luften bevæger sig hele tiden og forvrænger de billeder man får ind (en af fordelene ved rum-teleskoper er netop ikke at være under atmosfæren) men det kan man gøre noget ved, ved at bøje spejlet for at korrigere for lufturo.

Yay! Roman launched successfully!!! Roman is NASA's next big telescope after JWST, and it will be an absolute survey powerhouse. So excited for the coming years! 🔭

It's a pretty fun worker placement eurogame. There are some random elements that are perhaps a bit too relevant for the hard-core gamer, but is great for the storytelling. Also the use of "Candy" to gain extra actions, but with the risk of having a "sugar crush" is quite fun 😊

NASA alt text: Earthset captured through the Orion spacecraft window at 6:41 p.m. EDT, April 6, 2026, during the Artemis II crew’s flyby of the Moon. A muted blue Earth with bright white clouds sets behind the cratered lunar surface. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater has terraced edges and a flat floor interrupted by central peaks. Central peaks form in complex craters when the lunar surface, liquefied on impact, splashes upwards during the crater’s formation.

The whole-Earth-at-night photo from the #Artemis II mission was brighter than many expected. That was mostly due to camera settings; here’s another pic taken just before with diff settings. Digital photography is always subjective—even before processing! (HT @swapnakrishna.com @jasonc0.bsky.social)
An image of the entire Earth, with Northern Africa and the North Pole visible at the lower left. It looks like daytime but it is actually illuminated by moonlight. There’s a bright arc along the lower right where the sun is coming through from behind. There’s a bright dot on the lower right (Venus) and a glow (zodiacal light). A few stars can be seen in the dark beyond the Earth.An image of the entire Earth, with Northern Africa and the North Pole visible at the lower left. It is dark with muted colors.
