The laser beams of our Very Large Telescope pierce the star-filled sky of the Atacama Desert in #Chile

The lasers create artificial "stars" in the atmosphere, about 90 km above the ground, which then act as guides. By studying how they are blurred by the atmosphere, the telescope's deformable secondary mirror quickly reshapes itself in real time, yielding very sharp images. It’s almost as good as sending the VLT up into space!

A large telescope stands in the centre of the image, against a backdrop of thousands of stars above a desert landscape. The Milky Way galaxy is visible behind the telescope, and the sky itself glows slightly green towards the horizon. From the very centre of the telescope, four bright orange laser beams are projected ahead into the night sky.

#UMPlus - #UMPlus - A Planet Destroyed in Helix

universomagico.net/2025/04/un-

On March 4, 2025, the Chandra X-ray Observatory revealed this image of the Helix Nebula, at the center of which is a mysterious X-ray emission. Astronomers have studied this nebula for over 40 years, and this is the first time such an event has been observed at the center of a planetary nebula. A.....

A Planet Destroyed in Helix
Public
ESO

In case you missed it yesterday, using ESO’s Very Large Telescope (VLT), astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars.

This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair 😲

Did you find the #StarWars world, Tatooine, and its companion stars impressive? Then check this! 😉

ESO's Very Large Telescope (VLT) has discovered the first planet that not only orbits a pair of stars but does so at an angle of 90 degrees.

Both stars are brown dwarfs, objects bigger than gas-giant planets but too small to be proper stars. When tracking their orbits, astronomers found that the orbits themselves change over time. After carefully ruling out other explanations, they concluded that the gravitational tug of a planet in a polar orbit was the only way to explain the motion of the brown dwarfs.

The Sun is rising over Cerro Armazones in #Chile!

And so does ESO's ELT: with the structure of one of the dome’s sliding doors now fully installed, construction on the dome of the telescope has reached its highest point.

The occasion also marks over 60% completion of the ELT. It was celebrated today at ESO's Headquarters in Garching, Germany, as well as at the ELT construction site in Chile!
