I really miss the night sky in #Chile , in particular the Magellanic Clouds – two dwarf galaxies orbiting our home galaxy, the Milky Way.

In the Mapudungun language in south-central Chile they are known as lafken, labken or künchalabken (“the lagoons”), as well as rünanko (“the water wells”).

Here I photographed them above ESO's Paranal Observatory in northern Chile.

The first results from ESO telescopes on the DART controlled impact on an asteroid are out! Two teams monitored the aftermath of the collision with two instruments at ESO's Very Large Telescope: MUSE, which breaks up light into its constituent colours, and FORS, which can study polarised light. Both observations provided clues about the composition of the material ejected after the impact.

@astro_jcm Cool stuff! And the fact that the tail neatly fits between the brightest star trails brings me great joy 😃

Look at these images of Europa and Ganymede taken with ESO's VLT in Chile! The moons are tiny as seen from Earth, about the size of a 1 Euro coin 3-5 km away. Using adaptive optics we can measure and correct atmospheric turbulence, yielding sharp images like these – the smallest details are only ~150 km! I used to operate this instrument back when I worked at the VLT, and I loved observing Solar System objects like these.

I'm sure you love astronomical images taken with professional telescopes. But do you know what it takes to actually make them? You'll be surprised by how many people are involved!

I just wrote an article explaining the whole process, from the moment an astronomer has an idea to when you see the final result.

If you're in Chile or are planning to visit soon, ESO's observatories are reopening for in-person visits!

The tours are free, but you have to register in advance: eso.org/public/announcements/a

I'm biased 'cause I worked there for 7 years, but it's totally worth it!

This is one of the most spectacular sunsets I ever saw while working at ESO's Paranal Observatory in Chile.

The Atacama Desert is extremely dry, but clouds do show up sometimes. That day there were several dark clouds releasing very light rain that vaporised before reaching the ground. These wispy veils (called "virga") were lit by the golden sunset light, creating a lovely contrast with the blue sky above.

Can you trap a galaxy in a crystal ball? I tried! Back in 2018 I took this image of the Milky Way through a crystal ball from ESO's Paranal Observatory in Chile.

If you look carefully you can even recognise some constellations. Due to the way the ball projects the image, the constellations in the background and within the ball are symmetric relative to the center of the ball.
