In 1995, Hubble spent 10 days staring at a patch of sky about the size of a pinhead held at arm's length. The image revealed roughly 3,000 distant galaxies.
ILLUSTRATION · AIOver 10 days in 1995, Hubble imaged a patch of sky the size of a pinhead at arm's length and found roughly 3,000 distant galaxies.
The Hubble Deep Field team needed a patch of sky in a continuous viewing zone, free of interference from Earth, the Sun or the Moon. They chose a spot in Ursa Major, near the handle of the Big Dipper, that looked relatively empty.
The final image holds 342 separate exposures taken between December 18 and 28, 1995, assembled from blue, red and infrared light. It captured roughly 3,000 distant galaxies in various stages of evolution, NASA says.
