1/ This is the longest exposure I've ever taken: 8 months long! It shows the Sun's path on the sky between Apr 17 - Dec 11 2018, as seen from ESO's Paranal Observatory in #Chile.

This is part of a collaboration with Diego López Calvín, an expert in solarigraphy: https://solarigrafia.com

Diego sent me some of his hand-made #pinhole cameras, which I placed all over Paranal. So what do we see here? See thread below 👇

Time for another #introduction for the newcomers 😀 I'm an astronomer and science communicator at the European Southern Observatory.

In my previous life I used to study how galaxies form and evolve. I also helped my peers get their data as a support astronomer at ESO's Paranal Observatory in Chile. I now work full time as Media Officer at ESO's HQ in Germany.

I'm also an avid astrophotographer! Below is a pic of my previous "office" in Chile. 🤩

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.

#Introduction time I guess! I'm an astronomer and science communicator at the European Southern Observatory. I used to do research + technical duties at ESO's Paranal Observatory in Chile, but now I work full time on science communication at our HQ in Germany. I love astrophotography, so you can expect some cool night pics here ;-)
