Hubble Legacy Field Image Shows 500 Million Year Old Universe

NASA and the ESA released their latest Hubble Image, called the Hubble Legacy View, that shows the universe as it was 13.3 billion years ago, a mere 500 million years after the Big Bang yet still full of ancient primordial galaxies. The faintest of the galaxies in the image have a brightness just one ten-billionth of what humans can observe with their own eyes.

"Now that we have gone wider than in previous surveys, we are harvesting many more distant galaxies in the largest such dataset ever produced", Illingworth said.

The new Hubble Legacy Field image covers nearly the width of the full moon. The idea is to focus Hubble's limited time yet incredible resolving power on a small area of the night sky, year after year, and build the deepest and most complete image of space.

Astronomers have assembled a mosaic of almost 7,500 images taken of the distant universe, creating the largest and most comprehensive "history book" of galaxies ever made.

"Hubble has spent more time on this small area than on any other region of the sky", the press release said.

This full view of the Hubble Legacy Field shows the uneven edges cropped out of the "cleaner" image, above, showing off all of the roughly 265,000 galaxies contained in the composite.

'No image will surpass this one until future space telescopes are launched'.

The Hubble Legacy Fields program, supported through AR-13252 and AR-15027, is based on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy Inc., under NASA contract NAS 5-26555.

The contemporary mosaic seizes roundabout 30 times as varied galaxies as any former deep field view and traverses nearly width of the full moon.

The image yields a huge catalog of distant galaxies.

In the case of the Hubble Ultra Deep Field, the image captured 10,000 galaxies.

Katherine Whitaker catalog lead researcher said that such superlative high intent computation of the innumerable galaxies in this catalog sanction a broad swath of aggregation study.

Like watching individual frames of a motion picture, the Hubble deep surveys reveal the emergence of structure in the nascent universe and the subsequent dynamic stages of galaxy evolution. A quarter of a century the camera held 1.2 million targeted observations over 38 thousands of space objects, based on which it has trained about 13 thousand scientific papers. Hubble's surveys of disc galaxies aim to explore the relationship between these black holes and their local galaxies. Webb's infrared coverage will go beyond the limits of Hubble and Spitzer to help astronomers identify the first galaxies in the universe.
