En ramme om nattehimlen
ESOs observatorier er priviligerede steder, hvor astrofotografer kan tage fantastiske billeder af universet. Men det er ikke hele historien. Nogle gange er disse steder også ideelle steder til at tage udenjordiske billeder af vores egen planet. I dette billede har ESO-fotoambassadør[AH1] Gabriel Grammer lavet en spektakulær cirkeleffekt ved at bruge en fiskeøjelinse på sit kamera.
Den klare nattehimmel over Paranal-observatoriet ligner en glaskugle fyldt med stjerner, med platformen for ESOs Very Large Telescope (VLT) observatorium som ramme.
VLTs fire teleskoper, der hver er omkring 25 meter høje, kan ses nederst til venstre på billedet. De observerer nattehimlen, og den ene af dem sender sin røde laser ud i natten for at anvende adaptiv optik. De runde kupler med VLTs hjælpeteleskoper er spredt rundt i den øverste venstre del af billedet og kan nemt ses under den lysstærke Mælkevej. Lige over den røde laserstråle ses to utydelige pletter, der er den Store og den Lille Magellanske Sky. De er to af de nærmeste galakser i forhold til vores egen galakse.
Dette billede er en kombination af flere forskellige vidvinkeloptagelser, der er blevet sat sammen.
