The date(s) that the telescope made its observations and the total exposure time. The science instrument used to produce the data. "PI" refers to the Principal Investigator. Science Team: The astronomers who planned the observations and analyzed the data.Proposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.The physical size of the object or the apparent angle it subtends on the sky. Interstellar distances can also be measured in parsecs. Solar system are usually measured in Astronomical Units (AU). The physical distance from Earth to the astronomical object. One of 88 recognized regions of the celestial sphere in which the object appears. Right ascension – analogous to longitude – is one component of an object's position.ĭeclination – analogous to latitude – is one component of an object's position. Ī name or catalog number that astronomers use to identify an astronomical object. More details about the HLF can be found at. The full Hubble Legacy Field dataset has images from all three of Hubble's cameras - the WFC3/IR and WFC3/UVIS cameras as well as the ACS. Green: F606W (Wide V) and F850LP (SDSS z') The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. Several filters were used to sample broad and narrow wavelength ranges. These images are composites of separate exposures acquired by the ACS and WFC3 instruments on the Hubble Space Telescope.

Lying in this region is the XDF, which penetrated deeper into space than this legacy field view. ![]() The new portrait, a mosaic of multiple snapshots, covers almost the width of the full Moon. The wider view contains about 30 times as many galaxies as in the Hubble Ultra Deep Field, taken in 2004. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see. The tiny, faint, most distant galaxies in the image are similar to the seedling villages from which today's great galaxy star-cities grew. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang. The image mosaic presents a wide portrait of the distant universe and contains roughly 265,000 galaxies. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time. The ambitious endeavor, called the Hubble Legacy Field, includes several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The image, a combination of nearly 7,500 separate Hubble exposures, represents 16 years' worth of observations. This Hubble Space Telescope image represents the largest, most comprehensive "history book" of galaxies in the universe.
