Sans doute la plus belle image de la comète ATLAS, derrière un des télescopes du VLTI au Chili!

Looks like Comet C/2024 G3 ATLAS’s days may be numbered… the comet has faded & may have broken up post-perihelion as the nucleus fades from view, leaving a ‘tail-less wonder’ crossing the sky. Here's a great parting view w/ESO’s Paranal Observatory by Yuri Beletsky: www.instagram.com/p/DFF3LKtpIz4/

Exceptionnel !

Voici la toute 1ère image résolue d'une étoile... en-dehors de notre Galaxie la Voie Lactée. Elle est située dans le Grand Nuage de Magellan, à plus de 160 000 années-lumière !

Cette nouvelle image a été prise avec l’instrument GRAVITY du VLTI (European Southern Observatory)🧪

Image de l’étoile WOH G64, prise par l’instrument GRAVITY du Very Large Telescope Interferometer de l’Observatoire européen austral (VLTI de l’ESO). Il s’agit de la première image rapprochée d’une étoile en dehors de notre propre Galaxie, la Voie lactée. L’ovale brillant au centre de l'image est un cocon poussiéreux qui enveloppe l’étoile. Un anneau elliptique plus pâle qui l’entoure pourrait être le bord intérieur d’un tore poussiéreux.

1/ Milestone achieved by the VLTI upgrade GRAVITY+: a laser has been installed at each of the previously unequipped VLT Unit Telescopes.

This will dramatically enhance the VLTI observing power.

Four astronomical domes stand in a desert landscape, each launching a bright orange laser into the sky. A nearly full moon glows on the left of the image. The text “What are these lasers for?” is visible on the image.

M. Nowak discussing synergies with VLT Interferometer (VLTI) and #ELT at #ExoELT - ELT has the >30m aperture for sensitivity, but VLTI combines all 4 VLT telescopes over a 200m baseline for better angular resolution, complementing sensitivity of ELT #astrodon #astrosci

3/ At the centre of the Tarantula Nebula, the VLTI/GRAVITY+ observed the binary star in the inset below.

This object was originally thought to be an extremely massive star. Yet the new observations reveal its true binary nature, showcasing the stunning capabilities of the upgraded VLTI.

ICYMI Our VLTI has found a star that’s breaking records!

➡️ It’s the fastest star known in our galaxy
➡️ It comes closer to the #MilkyWay ’s supermassive #BlackHole than any other star found before.

This makes it the first star that could allow us to measure the black hole’s spin.

Let's dive into the dusty central region of the Milky Way!

There, a swarm of stars orbits an invisible, supermassive #BlackHole. As we get closer to it, we see these stars, as observed by the VLT (in 2019) and VLTI (mid-2021).

Quella che vedete è la prima immagine dettagliata di una stella che si trova fuori dalla nostra galassia. Si chiama WOH G64, è a 160.000 anni luce da noi ed è stata osservata dal Cile da VLTI, il Very Large Telescope Interferometer dell'ESO

🤔 But why do telescopes need lasers? Find out: https://www.eso.org/public/images/potw2503a

2/ This timelapse shows the lasers pointing at the VLTI observation target.

The video was created from photographs taken in early November on a nearly full-moon night. The lasers appear curved due to a projection effect.

This isn't a scene from #StarWars.

What you're looking at is the Tarantula Nebula. While those beams come from the lasers installed on the telescopes that comprise our VLTI.

But why are we sending lasers into the sky? Find out: https://www.eso.org/public/images/potw2616a/

Image of the super giant star Antares, at a distance of 555 light years, taken with the Very Large Telescope Interferometer (VLTI) in Chile. The tiny dot on the bottom left would be roughly the size of the Sun. At only ~15 Myr old, these stars live fast and die hard (supernova).

Mais l'étoile qui vient d'être photographiée se trouve très très loin. Elle est dans une autre galaxie, le Grand Nuage de Magellan, à 160 000 années-lumière de nous. C'est le gros nuage entre les télescopes de l'interféromètre du VLTI sur l'image ci-dessous.

A new solar system in the making?

For the second time ever, two planets have been directly observed forming around a host star. Our VLT and VLTI have helped astronomers confirm the presence of a second gas giant orbiting the star WISPIT 2.
