Helleristninger på La Silla
Billedet viser ESO 3.6-metre telesskopet, på La Silla Observatoiet i Chile. Nattehimlen domineres af den klare Måne, hvis lys er så kraftigt, at himlen bliver himmelblå!
Det der fanger øjet på billedet er den røde sten i forgrunden. På den er der indgraveret forhistoriske helleristninger - en hilsen fra fortidsmennesker på stedet. Omkring La Silla er der adskillige af denne slags tegn, men lige omkring denne sten er de fleste og flotteste.
I 1990 blev der foretaget en komplet fotografisk og topografisk registrering af disse indgraveringer. Billederne forestiller først og fremmest mennesker og dyr, og så nogle mærkelige geometriske figurer. Forskerne mener, at klippetegningerne stammer fra El Molle komplekset - den første kultur i den nordlige del af Chile. Geologerne mener, at området i det første årtusinde af vor tidsregning fik langt mere regn end nu, og derfor kunne dele af det, som nu er Atacamaørkenen understøtte forskellige civiliserede kulturer.
(Ikke alle klippetegningerne omkring La Silla er dog helt så gamle. Spøgefugle har for eksempel tegnet et teleskop og en Folkevogn på andre sten, men heldigvis uden at ødelægge de ægte tegninger)
