Cette semaine, nous testions l'optique adaptative de l'instrument #GRAVITY+ de l'interféromètre du #VLT (#VLTI). Avant l'installation des étoiles laser sur les télescopes unitaires 1, 2 et 3, nous avons qualifié le système avec le télescope 4, équipé d'étoiles lasers depuis des années pour d'autres instruments.

J'étais au QG de l'@esoastronomy en Allemagne, mais Anthony Berdeu était sur place et a pu capturer la magie de la #Lune dans le désert d'#Atacama.

An article published in the journal "Astronomy & Astrophysics" reports the creation of a detailed image of the red supergiant star WOH G64 and its surroundings, the first ever obtained of a star outside the Milky Way. A team of researchers led by astrophysicist Keiichi Ohnaka used the GRAVITY instrument on ESO's VLTI in Chile to obtain details of this star in the Large Magellanic Cloud.

An article published in the journal "Science" reports a study on the HD 148937 system, a binary system surrounded by a double nebula known as NGC 6164/6165. A team of researchers used the PIONIER and GRAVITY instruments and archival data from the FEROS instrument to collect the data necessary to conclude that it was originally at least a triple system and at some point two of the stars merged.
