Started boiling some Weißwurst without realising I'm all out of sweet mustard, and stores are closed today. Should I...
(a) Go out and buy mustard in a gas station.
(b) Use sriracha, the only other sauce I happen to have at home right now, and risk being deported from Germany.

'Scavengers Reign' is one of the best #SciFi #tv shows I've ever seen. HBO –oops, sorry, 'Max'– killing it is so dumb. I don't trust #Netflix much more in this sense, but if the show can have a second life there then so be it. While season 1 was pretty self-contained, I really want to keep exploring this fascinating world.

@grb090423 According to the article, season 1 will start streaming on Netflix (in some countries) by the end of the month, so at least there's that...

Me getting mentally ready to be super jealous of the upcoming #aurora pics from those of you living at higher latitudes.

@juandesant Recent NOAA forecasts show emissions all the way down to Seattle. I don't think you'll be lucky in Santiago, but there should be a nice display in Antarctica.

Paranal Observatory was my home away from home for many years. In this blog post Vanessa Peidro Cid, the Head of Paranal Logistics and Facilities, takes us on a behind-the-scenes tour of what it takes to run this small "town" in the Atacama Desert. A lovely piece by Elena Reiriz Martínez, one of our communication interns at ESO.

Happy to those who celebrate! Here's a pic I took a few years ago back when I worked at ESO's Paranal Observatory in . One of our 8.2 m telescopes was pointing at the centre of the , home to Sagittarius A*, a 4 million times more massive than the .

Astronomers devoted almost a century to unmask this beast:

until the Event Horizon Telescope finally imaged it:

@DelRider The laser excites sodium atoms in a layer 80-90 km above the ground, making them glow. This creates an artificial "star" that we can use to monitor atmospheric turbulence in real time, correcting it with a fast deformable mirror.

EDIT: forgot to mention that it's yellowish because it has a wavelength of 589 nanometres, chosen to excite those sodium atoms.

How are we building the largest dome ever? In the latest episode of Chasing Starlight we take you on a behind-the-scenes tour of the dome of ESO's Extremely Large Telescope in

It's 88 m wide and 80 m tall, and it will shelter the ELT and its optics & instruments from the harsh environment of the Atacama Desert –– a true feat of

Hace unos días tuve el placer de charlar de nuevo con Ángel Rodríguez Lozano en su programa Hablando con Científicos, donde expliqué algunos trucos para identificar imágenes astronómicas falsas.

Podéis descargar el audio aquí: https://cienciaes.com/entrevistas/2024/05/02/fake-astro/

La entrevista está basada en este artículo (en inglés) que escribí hace poco en el de ESO: https://www.eso.org/public/blog/csi-astronomy/

@defcon42 That's a good first-level approach. There are also some very serious astrophotographers out there that produce outstanding (and genuine) iamges, so it's also good to slowly build a list of those trustworthy photographers.
