L’osservatorio Vera C. Rubin in Cile ha pubblicato le sue prime immagini, frutto di 678 scatti in sette ore, rivelando con un livello di dettaglio mai raggiunto prima nebulose e galassie lontane.
Le prime immagini di Vera C. Rubin
Una delle immagini mostra la nebulosa Trifide e quella Laguna, situate a diverse migliaia di anni luce dalla Terra. Le immagini rivelano un universo “brulicante di stelle e galassie”, con colori rappresentativi che rendono visibili all’occhio umano le lunghezze d’onda captate dal telescopio, normalmente invisibili.
Il telescopio, finanziato dalla National Science Foundation (NSF, un’agenzia indipendente statunitense che supporta la ricerca scientifica) e dal Dipartimento dell’Energia USA, inizierà presto il progetto “Legacy Survey of Space and Time” (LSST), per monitorare il cielo ogni notte per dieci anni. In dieci ore ha già scoperto 2’104 asteroidi, sette dei quali vicini alla Terra ma non pericolosi.
