This isn't a scene from Star Wars.

What you're looking at is the Tarantual Nebula, and those beams come from the lasers installed on the telescopes of our Very Large Telescope Interferometer in #Chile. They create artificial stars 90 km above the ground to correct atmospheric turbulence, allowing the VLTI to observe faint targets.

But why are four telescopes observing the same target? Find out: https://www.eso.org/public/images/potw2616a/

An astronomical image featuring the backdrop of the dark night sky with a faint grey-blue speckle at the centre. The nebulous cloud has the shape of a four-leaf flower. Four orange laser beams are pointing to it.

“It was an unforgettable moment“, said photographer Julien Looten when he saw the Carina Nebula with his own eyes at our Paranal Observatory in #Chile.

Its southern location and its uniquely dark skies made it possible for Julien to capture this breathtaking view. The Carina Nebula — a massive star-forming region — is visible here as a big pink spot above one of the four Auxiliary Telescopes.

The image shows the Milky Way band seemingly pouring into a telescope, right below the centre of the image. Within the Milky Way right above the telescope, the Carina Nebula is visible as a pink spot, which marks the very centre and focus of the image. Additionally, one of the Magellanic Clouds is visible in the left side of the picture right above the horizon.

New instance, new #introduction !

Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes.

One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!

We’re looking forward to chatting with all of you about #astronomy

And many thanks to @sebinthestars for running our former instance!

A drone photograph of a gigantic telescope in the desert, at sunset. The telescope dome is under construction, and partially covered in cladding. The sliding doors of the dome are open, revelaning the telescope inside: a cylindrical structure of white criss-crossed beams. The dome is surrounded by huge cranes, and the entire scene is bathed in the golden light of the setting Sun in the background.

When your mirror gets dirty at home, you can just grab a cloth and some spray to clean it. But what about the ultra-precise, reflective mirrors of telescopes? 🤔

Things can get a bit more complex. This image shows you part of the cleaning process for the main mirror of the ESO 3.6-metre Telescope at La Silla Observatory, #Chile.

Discover how it's done: https://www.eso.org/public/images/potw2524a/

In the centre of the image lies a white cylinder block with engineers and technicians standing in the centre, their torso peeking out of the hole. They are standing around the block wearing bright hazmat suits, face shields, clear gloves, and hairnets. They are cleaning the surface layer of the mirror blank.

1/ ☄️ #Comet C/2024 G3 (ATLAS) is gracing our skies, and we’d like to share some amazing images from our Paranal Observatory in #Chile!

This stunning shot by our friend Yuri Beletsky, with the comet next to an Auxiliary Telescope, is today's Astronomy Picture of the Day. Congrats, Yuri!

A sunset photograph at an observatory. The colour of the sky changes from blue, almost purple, to golden at the horizon. There’s a white closed telescope dome with a spherical top. To its left, the comet stretches diagonally across almost the entire image, as if it had been painted on the sky with a gigantic brush. The tail of the comet is white and full of intricate filaments.

We've just started installing the aluminium cladding that will protect ESO's Extremely Large #Telescope from the harsh conditions of the Atacama Desert in #Chile.

It's amazing to see this project take shape. And it's hard to convey just how big this is –– the dome is 80 m tall!

#astrodon #astronomy #engineering #technology #space

The large, steel grey skeleton of a telescope dome sits on top of a concrete foundation. At the front of the dome, light grey metal cladding covers the structure. To the right on the horizon, the yellow Sun is setting, washing the sky in shades of purple and blue. To the left, two long yellow crane arms jut into the sky.

Carlos Francisco 📖 a publié une critique de La casa de los espíritus par Isabel Allende

Pas de couverture — Isabel Allende: La casa de los espíritus (Spanish language, 2010, Debolsillo)

Mi primera lectua de Isabel Allende

5 étoiles

Se nota claramente la influencia de "100 años de Soledad" de Gabriel García Márquez en este libro. Eso para mi es algo muy bueno, considerando que el de García Márquez es uno de mis libros favoritos de la vida. En la parte de "realismo" del realismo mágico, siendo latinoamericano y particularmente chileno, uno se siente identificado con una realidad existió y que aún existe. Formas de pensar y de vivir, y los terribles acontecimientos ocurridos durante la dictadura cívico-militar. "La Casa de Los Espíritus" no alcanza a estar al nivel de la gran obra de Marquez, pero creo que está solo un pequeño peldaño por debajo.
