Armazones topløs
Godt med støv og en vrimmel af svært entrepenørudstyr dækker toppen af bjerget Cerro Armazones, hvor ESOs fremtidige teleskop the European Extremely Large Telescope (E-ELT) skal bygges.
Billedet her er taget fra en quadcopter af ESO Photo Ambassadør Gerd Hüdepohl. Det giver en fornemmelse af, hvor enormt meget arbejde, der skal til for at fjerne toppen af et bjerg. I baggrunden ses noget af Chiles Kystbjergkæde, hvor man finder Cerro Paranal med Very Large Telescope, på den højeste af bjergtoppene i det fjerne.
Ud imod horisonten blåner bjergene i disen, selv her over Atacamaørkenen, som er et af Verdens tørreste områder. Der er ikke mange detaljer at se i ørkenen, men den har alligevel sin egenartede skønhed, og den vil i fremtiden danne baggrund for udsigten fra Verdens største teleskop til observationer i optisk og infrarødt lys.
Den klare himmel over Atacama vil give perfekte forhold for E-ELT, når teleskopet skal kigge ud i Universet, med en billedskarphed som kommer til at overgå selv Hubble rumteleskopet. Når det store, nye teleskop bliver klar, kommer det til at bidrage til jagten efter beboelige exoplaneter, og til at se endnu længere tilbage i tid og rum til den tid, hvor de første stjerner og galakser blev dannet. Og det mest spændende bliver som altid de opdagelser, som man ikke havde regnet med.
E-ELT får et spejl med en diameter på 39 meter. Det vil gøre teleskopet i stand til at samle mere lys end alle Verdens nuværende 8-10 m teleskoper tilsammen. Observatoriekuplen, med en diameter på 86 meter, kommer til at tårne sig 74 meter op, som en ny, menneskeskabt bjergtop. Men på det majestætiske Cerro Armazones bliver det alligevel kun en mindre knyst, selvom det er den moderne astronomis største og nyeste teleskop.
