A new night begins at ESO’s Paranal Observatory, and comet C/2024 G3 makes a grand entrance ☄️ 😎 With it, a swarm of satellites – a growing concern for the darkest skies in the world...

At ESO we have worked extensively not only to measure the impact of satellite constellations on optical and radio observations, but also to escalate this issue to the highest levels.

➡️ eso.org/public/about-eso/dark-…

Thanks to the joint effort of several countries and institutions, this problem is now discussed annually in the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space.

Dark and quiet skies preservation

ESO has been actively involved in the campaign for dark and quiet skies preservation, and is participating in many projects supporting the reduction of pollution resulting from errant light, satellite constellations and aeroplanes.

This Picture of the Week shows the clearest image yet of a filament from the cosmic web of dark matter!

Captured with ESO’s Very Large Telescope (VLT) in #Chile and made of gas clumped together by the influence of dark matter, it stretches out for 3 million light-years, connecting two distant galaxies in the early Universe 😯

Observing the faint glow of this gas required about 150 hours of observing time!

The image shows countless stars and galaxies in the background. Two galaxies are shown at the forefront, each with a bright nucleus, which indicates the presence of a quasar. The galaxies appear like large nebulae, without a concrete shape. The content of the galaxies extend beyond their immediate shape, forming a bridge that connects the two galaxies. This bridge is a cosmic filament.

New laser-sharp vision for Paranal’s facilities! 😎

In this image, you see the first of nine new lasers that are being built for our Extremely Large Telescope (ELT), currently under construction, and Very Large Telescope Interferometer (VLTI), both located at Paranal in #Chile

The laser projection systems are being built in the Netherlands, and the first one has now successfully passed a review by our engineers ✅ 🎉

🤔 But why do telescopes need lasers? They excite sodium atoms high up in the atmosphere, creating artificial "stars". By monitoring these "stars" we can measure and correct atmospheric turbulence in real time with a fast deformable mirror, obtaining very sharp images!

At the centre of the image, a big square machine is standing, its top part a closed grey box, containing a laser, resting on top of an illuminated network of intricate machinery. It is standing on a yellow slider. To the right of the machine, a man wearing safety goggles and gloves is standing on a stepping ladder, installing a part on a big black vertical tube, as high as he is, attached to the back of the square machine. On top, the tube is glowing yellow.

Ultima Thule, a Kuiper Belt object visited by the New Horizons spacecraft in 2019. Here are some key points from the image and its description: Close Encounter: New Horizons flew within 3,500 kilometers of Ultima Thule, much closer than its approach to Pluto. Navigational Precision: This close encounter required exceptional navigational precision, given the vast distance from Earth. Sharpest Image: The image is described as the "most detailed picture possible" of Ultima Thule, with a resolution of about 33 meters per pixel. Intriguing Features: The image reveals the object's shape and surface features, including bright areas and dark patches. Bot described Alt

Two telescopic images of the planet Neptune side by side. The left one, labeled "adaptive optics", is very crisp and shows detailed white clouds against the planet's deep blue disc. The right one, labeled "no adaptive optics", shows a blurred disc where no details can be discerned.

Adaptive Optics

Astronomers have turned to a method called adaptive optics. Sophisticated, deformable mirrors controlled by computers can correct in real-time for the distortion caused by the turbulence of the Earth's atmosphere, making the images obtained almost as…

After all, black holes are not as destructive as we thought! 😮

Using our Very Large Telescope, astronomers have discovered, for the first time ever, a binary star close to our galaxy's supermassive black hole. Binary stars are extremely common throughout the galaxy but not close to the black hole, which makes this new system really interesting!

Named D9, it looks like a single dot, but its speed wobbles periodically back and forth, revealing that this is in fact two stars orbiting each other as they move together around the black hole.

The image shows a section of our galaxy, the Milky Way, in the night sky. This is where the supermassive blackhole and the newly discovered binary star around it are located. The Milky Way traverses the image diagonally and is a spectacle of light and darkness. Its millions of stars illuminate the picture, but light is often blocked by large dark clouds of gas and dust that create eerie shapes. It also contains stars and small nebulae of red, pink and blue colours. In the background, the sky is dark, but full of stars of different sizes and colours. The centre of the galaxy with the binary star appears in a close-up on one corner of the image. This is a pixelated mapping of the hydrogen emission of the region around the star pair D9. Bright orange to white patches represent high hydrogen levels (indicating stars), black, represents very low hydrogen emission. Most of the centre of the image is dark with a few wisps of dark orange. The black hole and the binary D9 are indicated.

First ever binary star found near our galaxy’s supermassive black hole

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy.

#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

The giant metal frame of a dome takes up most of the picture frame, contrasting with the brown hills and a thin horizontal line of blue sky in the background. The dome's frame is not yet fully covered in the middle, so the dark brown landscape behind it shows. The big opening in the dome's roof shows the interior, still a construction site with a structure of white beams. In front of the big building is one red crane, taller than the dome.
