The Hubble Deep Field image holds 342 separate exposures taken between December 18 and 28, 1995. The picture we see was assembled from blue, red, and infrared light. The combination of these images allows astronomers to infer the distance, age, and composition of the galaxies photographed.
The Hubble Deep Field (HDF) is an image of a small region in the constellation Ursa Major, constructed from a series of observations by the Hubble Space Telescope. It covers an area about 2.6 arcminutes on a side, about one 24-millionth of the whole sky, which is equivalent in angular size to a tennis ball at a distance of 100 metres. [ 1 ]
This view of nearly 10,000 galaxies is called the Hubble Ultra Deep Field. The snapshot includes galaxies of various ages, sizes, shapes, and colours. The smallest, reddest galaxies, about 100, may be among the most distant known, existing when the universe was just 800 million years old.
With the Hubble Deep Field, we reach back nearly to the time when galaxies emerged from the chaos of the big bang. This image, called the Hubble Ultra Deep Field, shows 28 of the more than 500 young galaxies that existed when the universe was less than 1 billion years old.
An astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
Take a tour of this historic image from the Hubble Space Telescope. This long exposure of a tiny patch of the sky allowed astronomers to understand the scale, structure, and development of...
Hubble Deep Field. In 1995, the Hubble Space Telescope spent 10 straight days in a unique experiment, staring at a dark, seemingly empty patch of sky ― about the size of a pinhead held at arm's length ― near the Big Dipper. The goal was to see what, if anything, could be found there.
The 2009 infrared image of the Hubble Ultra Deep Field has been an extremely fertile hunting ground for scientists who study the early Universe. Several candidates for the most distant galaxy ever observed have been spotted in this image.
This Hubble Space Telescope image, known as the Hubble Ultra Deep Field, reveals about 10,000 galaxies and combines ultraviolet, visible, and near-infrared light. Two programs that will use the James Webb Space Telescope will add more detail to this image, capturing thousands of additional galaxies in a fuller range of infrared light.
The Hubble Ultra Deep Field (HUDF) peers deeper into the universe than any previous visible-light image. Multiple observations of the same small patch of sky were combined for an equivalent exposure time of more than 11 days. Revealed within the image are thousands of galaxies located many billions of light-years away.
