Attraverso una sfera di cristallo
Le meraviglie del cosmo hanno ispirato soggezione fin dall'alba dei tempi. Migliaia di anni fa, le civiltà antiche osservavano gli oggetti celesti per segnare le stagioni e il tempo, per creare miti e storie e per dare un senso al cosmo che li circondava - e gli astronomi moderni sono affascinati dalla bellezza e dal mistero del cielo notturno allo stesso modo.
Abbiamo girato gli obiettivi della macchina fotografica verso il cielo sin dalla nascita delle prime forme di fotografia, sperando di catturare lo spettacolo di un cielo scuro punteggiato da una miriade di luci. Ma è stato solo nel 1850 che la prima stella è stata catturata con una macchina fotografica. I decenni successivi videro lo sviluppo di apparecchiature fotografiche sempre più complesse e le immagini di oggetti e fenomeni celesti creati con la luce proveniente da tutto lo spettro elettromagnetico sono diventate da allora la pietra angolare dell'astronomia moderna.
Questa bellissima fotografia dell'arco scintillante della Via Lattea visto attraverso una sfera di cristallo, che brilla di miliardi di stelle e di chiazze intrecciate di gas e polveri, offre una prospettiva intrigante sulla nostra galassia natale. È stata scattata dall'ambasciatore fotografo dell'ESO Juan Carlos Muñoz-Mateos, che spera di "aiutare gli altri a sentire cosa significa guardare il cielo notturno da uno dei luoghi più bui e aridi della Terra" - il deserto di Atacama, sede dell’osservatorio Paranal dell'ESO.
