Es ist Zeit für eine Feedback-Folge: Franzi und @pikarl sprechen über grabende Reptilien, über schrecklich kranke Dinos und über die schreckliche verwirrende Raumzeit nahe am Ereignishorizont. 🦕 🦖 ✨

Did you know we have a remote observatory on Mars?
When NASA's Perseverance rover isn't busy studying the Martian landscape, it turns its gaze upward to do a little skygazing. This is its view of Mars's inner moon, Phobos.

The Event Horizon Telescope has unveiled how Sagittarius A*, the supermassive black hole at the centre of our galaxy, looks like in polarised light, which tells us a lot about the magnetic field around this monster.
The lines overlaid on the image below mark the orientation of the polarisation, from which astronomers can work out the structure of the magnetic field around the black hole.

Wooooaaahhhh!
The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.
To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯
Look at ALL those galaxies, all in that tiny white box.

Dodgy image with white boxes is my own.

These mean looking sunspots are the cause of the strongest geomagnetic storm (G5 - Severe) in 20 years!
They are really huge, spanning about 16 Earth diameters. Auroras are happening now and probably will continue over the weekend.

Very sad to hear of the passing of Ed Stone, who has died at the age of 88.
Best known perhaps as the project scientist from 1972 to 2022 for the Voyager missions to Jupiter, Saturn, Uranus, & Neptune, Ed played a key role in the history of space science, including 10 years leading NASA JPL.
I met him at a space particle & fundamental physics conference at CERN in 2012, where I took these pictures. Originals: https://flic.kr/s/aHsjCM5rJJ

Are the colours in astronomical images real? What do these colours mean? And what about images that aren't taken in visible light?
We get these questions all the time, so in the latest episode of Chasing Starlight we show you how these colourful images are made:
IFT-6 orbital test flight is NET November 18, 2024.
Local launch window opening at 1600. Allows for Ship 31 to flip and land in daylight in the Indian Ocean.
Raptor relight added as an objective (needed to prove the upper stage can do a safe orbital insertion and de-orbit). Booster 13 will attempt RTLS and landing at OLM 1 just like Booster 12.

Celebrating the women working on ESA/NASA #SolarOrbiter mission on this #WomenInScience day.
At the Max Planck Institute for Solar System Research, we do cutting edge scientific research on our Sun, the planets and their moons, asteroids and comets. Posts will be in English und manchmal auch auf Deutsch.

You'll be hearing a lot about the amazing new Vera Rubin Observatory today. Here's a peek at its most important feature: an unusual optical design that gives it a HUGE field of view, allowing it to scan the entire visible universe, over and over.

🚨 Astronomers have witnessed the dawn of a new solar system!
Using ALMA and JWST they observed the first specks of planet-forming material — hot minerals beginning to solidify around HOPS-315, a baby star 1300 light-years away.
This marks the first time a planetary system has been identified at such an early stage in its formation – a window to the past of our own Solar System.
