Having an "ñ" in my surname means constantly being gaslit by online forms that tell me my name can't contain special characters only to then tell me that my password must contain special characters, three emojis and a valid chess move.

Carl Sagan would've turned 90 today. Reading 'The Demon-Haunted World' as a teenager profoundly shaped the way I think today. Almost 30 years later the book remains (sadly) relevant...

I have my #Halloween costume ready, and you?

Just finished rewatching Fringe 😢 I had so much fun looking for hidden references to things I knew were going to happen, and I was genuinely surprised at how many of them there were! But at the same time I had forgotten enough plot details that I was still surprised every now and then. I'm going to miss Walter and his quirky quotes...

I can totally relate.

The thousands of edge sensors and actuators of ESO's Extremely Large Telescope have been completed! They are key to ensure that that 798 hexagonal segments of the ELT's primary mirror work together as a single 39 m wide mirror, with nanometric accuracy.

I would've done the same.

@lain Normally you can't see them so far south, but there's some pretty intense activity going on.

My first #aurora pic! I took this last night from Mayrhofen, a town in the Alps in #Austria. I couldn’t really see it by eye due to clouds and some light pollution, but it was definitely there, I imagine it was even brighter at higher latitudes!

And a closeup shot of the comet over the Llullaillaco volcano:

If you live close to the #Munich area, save the date! On 3 October we'll welcome everyone to the headquarters of the European Southern Observatory in Garching, as part of the Open House Day in the Garching campus.

There'll be lots of activities, check this link for the full programme: https://www.eso.org/public/announcements/annlang24001-de/?lang

Looking forward to seeing many of you!

1/ It's amazing that we can see details on the surface of some stars, but watching them move is even cooler 🤩

Using ALMA, astronomers have followed the motion of gas bubbles on the red giant star R Doradus over the course of a month. The bubbles are huge, about 75 times bigger than the Sun!

Here's an old pic I took back in 2019, showing the UT4 telescope at ESO's Paranal Observatory shooting its four mighty lasers. These lasers excite sodium atoms high up in the atmosphere, creating fake "stars" that we monitor in real time to measure and correct atmospheric turbulence, thus yielding very sharp images.

The two faint smudges flanking UT4 are he Andromeda (left) and Triangulum (right) galaxies.
