This circular mosaic was created from thousands of sky images taken by the Pan-STARRS Observatory, a 1.8-meter telescope located on the volcano Haleakalā on Maui, Hawai`i. The centre of the circle marks the north celestial pole, while the outer boundary corresponds to a declination of −30 degrees — the southern limit of the survey from that location. Each part of this image was visited multiple times during the survey with each location imaged in five different colors with multiple images per color to catch objects changing in brightness and to find moving objects such as asteroids. This dataset is a powerful example of an astronomical survey, in which the sky is systematically photographed to build large, uniform catalogs of celestial objects.
The wide, bright band running roughly from top to bottom is the Milky Way, with the Galactic centre appearing near the lower edge where the glow is strongest. Across the image are hundreds of millions of detected sources, most of them stars within our own galaxy, along with many distant galaxies in the background. Surveys like Pan-STARRS are essential for studying the structure of the Milky Way and for discovering new objects across vast areas of the sky.

Bildunterschrift: Questo mosaico circolare è stato realizzato a partire da migliaia di immagini del cielo acquisite dall’Osservatorio Pan-STARRS, un telescopio da 1,8 metri situato sul vulcano Haleakalā a Maui, nelle Hawaii. Il centro del cerchio indica il polo nord celeste, mentre il bordo esterno corrisponde a una declinazione di −30 gradi — il limite meridionale dell’osservazione da quella posizione. Ogni parte di questa immagine è stata visitata più volte durante l'indagine, con ogni posizione ripresa in cinque colori diversi e più immagini per colore, al fine di catturare oggetti che cambiano di luminosità e individuare oggetti in movimento come gli asteroidi. Questo set di dati è un potente esempio di indagine astronomica, in cui il cielo viene fotografato sistematicamente per costruire cataloghi ampi e uniformi di oggetti celesti.
L'ampia fascia luminosa che si estende approssimativamente dall'alto verso il basso è la Via Lattea, con il centro galattico che appare vicino al bordo inferiore, dove il bagliore è più intenso. Nell'immagine sono presenti centinaia di milioni di sorgenti rilevate, la maggior parte delle quali sono stelle all'interno della nostra galassia, insieme a molte galassie lontane sullo sfondo. Rilevamenti come Pan-STARRS sono essenziali per studiare la struttura della Via Lattea e per scoprire nuovi oggetti in vaste aree del cielo.
