A city on Mars?!
Well, close, but no. It's #ESO's Paranal little town of about 150 people in the Chilean Atacama Desert, next to the Very Large Telescope (#VLT).

I've been getting myself excited about getting the MAVIS instrument (https://mavis-ao.org/) on the telescope, even though that's still ~3 years off.

I was looking at this gorgeous image of Jupiter taken by the Hubble Space Telescope (https://esahubble.org/images/heic2017a/) and realising that MAVIS could do this with significantly higher resolution. Thanks to being on an 8 metre rather than 2.4 metre telescope MAVIS will have 3.3x the resolving power of HST, and the pixel sampling will be 5.4x finer (7.36 mas vs 40 mas).

I'm just looking at this 400% zoom crop and imagining a MAVIS image that's pin-sharp at the same magnification.

When a #star like our #sun reaches the end of its life, it can ingest the surrounding #planets and #asteroids that were born with it. Now, using the #EuropeanSouthernObservatory's #VeryLargeTelescope (#ESO's #VLT) in Chile, #researchers have found a unique signature of this process for the first time—a scar imprinted on the surface of a #whitedwarfstar.

What's the mass of #SagittariusA*? Using #GRAVITY at #ESO #VeryLargeTelescope #VLT, a team led by #MPE #PhDStudents Diogo Ribeiro & Antonia Drescher have measured the mass of the #blackhole⚫ in the center of our #milkyway by analysing the motion of swirling gas, so-called "#flare".

The power of multiwavelength astronomy in action: A research group led by Philipp Weber of the Universidad de Santiago de Chile (USACH) and Millennium Nucleus on Young Exoplanets and their Moons (YEMS) used ALMA to check on a young star, V960 Mon. Beyond the dust detectable with SPHERE, ALMA showed spiral arms of gas that are fragmenting, and have masses that can be progenitors of future giant planets.

0h15. "Réveil", même si j'ai dormi en pointillés sur les 5 dernières heures.

Vérif météo #VLT sur les webcams @ESO. Dernière image à 22h CEST. Tout clair. L'ELT en construction. Les télescopes auxiliaires m'attendent. On voit même le volcan à 190 km.

On ne va pas y échapper.

À J-1 d'#observations à distance avec l'interféromètre du #VLT. L'impatience commence à monter alors que je prépare mon planning de la nuit prochaine. 😃
