The new mosaic captures roughly 30 times as many galaxies as any previous deep-field view and spans nearly the width of the full moon, according to the NASA statement.
In the case of the Hubble Ultra Deep Field, the image captured 10,000 galaxies.
The image yields a huge catalog of distant galaxies.
This graphic reveals close-up images of 15 galaxies from the 265,000 galaxies in the Hubble Legacy Field.
"Such exquisite high-resolution measurements of the numerous galaxies in this catalog enable a wide swath of extragalactic study", said Dr. Katherine Whitaker, an astronomer at the University of CT, in Storrs.
The subsequent Hubble Ultra Deep Field from 2004 revealed almost 10,000 galaxies in a single image.
The Hubble observes ultraviolet wavelengths, which the atmosphere filters out, and it collects visible light.
The vast number of galaxies in the Legacy Field image are also prime targets for future telescopes. If Hubble had taken the images in one back-to-back observation, it would have lasted 250 days.
Dr Van Dokkum said astronomers hope to expand the multi-wavelength range of the images NASA's planned Wide Field Infrared Survey Telescope which will allow it to explore an even wider area of space than HLF. The galaxy was received "Hubble" to study the Central regions 145 a nearby spiral galaxies.
