Hubble ha festeggiato i suoi 25 anni in orbita a caccia di stelle e dei misteri dell’universo. Lanciato il 24 aprile 1990, il telescopio spaziale è stato uno strumento indispensabile per molte scoperte da parte degli astronomi.
Per l’occasione, la NASA ha rilasciato una spettacolare immagine di una regione di spazio a 20'000 anni luce dalla Terra dove nascono molte stelle, che danno l’impressione di un fuoco artificiale cosmico.
Altre immagini catturate dal telescopio sono diventate famose nel corso degli anni, in particolare un’immensa formazione di polvere interstellare, battezzata "Pilastri della creazione".
