Et funklende bånd af stjerner – Den sydlige Mælkevej over La Silla
Dette panoramabillede, taget af Alexandre Santerne, viser vores hjemgalakse Mælkevejens skive indefra, samt en kold vinternat med et drys af sne på ESOs La Silla-observatorium i Chile. Fra vores udsigtspunkt inde i Mælkevejen, ses dens skive som et funklende bånd af stjerner, der strejker sig over himlen. I dette panoramabillede er Mælkevejen forvrænget til en halvbue på grund af vidvinkelprojektionen.
Over bakken i venstre del af dette billede kigger ESOs 3,6-meter teleskop, hjemstedet for verdens bedste exoplanet-jæger, HARPS (the High Accuracy Radial velocity Planet Searcher) frem. Langt til højre er det schweiziske 1,2-meter Leonhard Euler Telescope, bygget og drevet af Geneva Observatory.
Der er en række grunde til at La Silla er et ideelt sted at observere nattehimlen i al almindelighed, og Mælkevejen i særdeleshed. Først og fremmest er den placeret på den sydlige halvkugle, der giver os et bedre udsyn til den rige, centrale del af galaksen, og dernæst er den beliggende langt fra lys og forurening fra byerne, i en højde på 2400 meter over havets overflade, hvilket giver mørke nætter og en klar atmosfære.
Alexandre indleverede dette billede til Your ESO Pictures Flickr gruppen. Flickr-gruppen bliver jævnligt gennemset og de bedste billeder bliver udvalgt til at medvirke i vores populære Ugens Billeder serie, eller i vores galleri. Siden at han indsendte billedet er Alexandre også blevet en ESO foto-ambassadør.
