The Atacama Desert in #Chile has some of the darkest night skies in the world, perfect for #astronomy. But it's also a very seismic area. When an #earthquake hits, how do we keep our telescopes safe? We tell you all about it in this new video: https://youtu.be/y_nfFwKwmmM
Soon the telescope platform at ESO's Paranal Observatory in #Chile will look very different at night: all four of the 8.2 m telescopes of the VLT will be equipped with lasers! This is one of the ongoing upgrades of the GRAVITY+ instrument, which will allow us to study black holes, stars and planets like never before.
@astro_jcm I managed to see a guide star operating at Lick Observatory once. Photos show a bright yellow beam, but I was only able to see it in my peripheral vision. Very cool to see this perfectly straight yellow beam projecting upward from the dome!
Photographer Yuri Beletsky: ‘I captured this view at one of the remote sites of the Atacama Desert in Chile. The Galactic centre was already shining high in the sky, with the zodiacal light beautifully complementing it on the right. The blue colour was as real as the stars in the sky, adding a touch of magic to the scene’
Photographer Lorenzo Ranieri: ‘The plateau of the Atacama desert, a potentially dangerous area due to its designation as a mountain lion reserve. The area around this remarkable mass of rocks adorned with tufts of burnt grass was littered with the bones of small animals and footprints of a significant size, indicating the presence of lions’
Presentación del disco de Electrodomésticos, «Mirar la Luz», en el Teatro Oriente.
Además de la banda con Carlos Cabezas en voz y guitarra, Edita Rojas en batería, Masiel Reyes en bajo y Valentín Trujillo en teclados, se sumó Angelo Pierattini en guitarra -un músico a quien admiro mucho-.
También estuvo la actriz Amparo Noguera en la voz de una excelente reversión de "Yo La Quería" (Yo lo Quería). #Electrodomésticos#Conciertos#CarlosCabezas#EditaRojas#AngeloPierattini#Chile#TeatroOriente
Happy #BlackHoleWeek to those who celebrate! Here's a pic I took a few years ago back when I worked at ESO's Paranal Observatory in #Chile. One of our 8.2 m telescopes was pointing at the centre of the #MilkyWay, home to Sagittarius A*, a #BlackHole 4 million times more massive than the #Sun.
Astronomers devoted almost a century to unmask this beast:
@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 #telescope 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 #Chile
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 #engineering
Need to blow off some steam? You're not alone –– galaxies sometimes do that too. Ok, not steam per se, but still.
This is NGC4383, observed with ESO's Very Large Telescope in #Chile. This nearby galaxy is undergoing a burst of intense star formation that is ejecting huge amounts of gas out of the galaxy, seen here as red filaments. 1/2
This image was taken with the MUSE instrument at the VLT. MUSE doesn't take images per se. Instead, it breaks the light coming from every point within its field of view into a rainbow or spectrum. This provides astronomers with a wealth of information about the motion and chemical composition of the gas and stars at different points within the image.

MEGADETH Visits Astronomical Observatory In Chile
Professor Reggie Almeida of the Gracie Barra Brazilian jiu-jitsu school in Spring Hill, Tennessee, who has been traveling with MEGADETH on the band's recent tours, has uploaded video of the Dave Mustaine-fronted outfit's visit to the Observatorio Manuel Foster, or Manuel Foster Observatory, prior...
Today, on International Earth Day, I bring you a photo of my favorite Chilean plant. Puya alpestris or chagual, this beautiful plant is slow growing, and can take many years to flower, between 2 and 5 years. Human action has caused the population of these plants to decrease, which is affecting species such as the largest butterfly in Chile, which is now in danger of extinction. You never know how the disappearance of one species could doom another. #Earthday#naturephotohraphy#chile#plants#wildflowers#endemic#nature#takecareofthe planet
If you have the chance to see the upcoming solar #SolarEclipse on April 8, go for it! Even if you've seen an annular #eclipse or an almost total one, the difference between that and a fully total one is like night and day –– pun intended!
Here's a shot I snapped of the 2019 eclipse from ESO's La Silla Observatory in #Chile. I vividly remember seeing the #Moon 's shadow crawling towards us from the Pacific Ocean. Unforgettable!
Eso debe tener alguna justificación técnica, por ejemplo, una relación con el sueldo mínimo.
Al menos según yo, lo que tiene sentido es que los parlamentarios ganen específicamente el sueldo mínimo. Tal vez con cuea un margen porcentual de un dígito por encima, onda 105% del sueldo mínimo. No más. Después de todo, deben representar a todos los chilenos, y no pueden ponerse adecuadamente en los zapatos del chileno promedio y tomar las decisiones acorde a eso si les sobra la plata.
@carloshr a modo de ejemplo, durante 2 años el barrio se comprometio con la junta de vecinos, y practicamente estabamos mas de un "representante" por calle en la instancia... porque queriamos llevar algunos cambios en nuestro barrio, que ni siquiera implicaban grandes recursos para el municipio, sino mas bien que se nos tomara en cuenta en las decisiones y planes de futuro... todo al traste, pues hasta el presi de la junta se termino frustrando.
La supuesta democracia representativa piramidal que domina a la politica chilena es eso, piramidal... no entrega una sola gota de poder a nadie debajo de ellos.
Lo mismo en mi epoca de estudiante universitario en region... y las regiones son parte del culo del pais. De democracia, solo la palabra.
Mas representantes en las diferentes instancias, para repartir un poco mas el poder...
Menos representantes tendera a concentrar aun mas el poder en menos manos.
Igual hay un negacionismo cuático porque todos se acuerdan de la primera línea pero pocos de esos quieren recordar que había un descontento generalizado con la clase política y la economía

Déjame ver… ¿“el censo es una herramienta de los comunachos para que la ONU pueda agendar sus vacunas falsas que hacen a al gente gay y ver en qué sectores tienen que instalar sus antenas 5G de noticias falsas”?
Here's a pic I took a few years ago at ESO's Paranal Observatory in #Chile, with the UT4 telescope aiming its four mighty lasers in the direction of the Large Magellanic Cloud, a small galaxy orbiting our own.
What do we use the lasers for?
(a) Play with space #cats 🐱
(b) Destroy rebel planets 💥
(c) Measure atmospheric turbulence 💨
Pilme (Pseudomeloe sanguinolentus), characteristic beetle of the flowering desert. Unlike the female, the male has white spots on its back.
In Chile, the times I went to the flowery desert. I had a great time watching these beetles, it was fascinating to watch them eat small succulents with their voracious appetite. With my small Sony DSC-WX60 camera, I captured that fascinating moment. #naturephotography#chile#coleoptere#meloide#flowerfuldesert #atacamadesert
