NASA scientists release 'history book' Hubble Telescope galaxy images

NASA and the ESA have released a new image called the Hubble Legacy Field that shows the universe as it was 13.3 billion years ago, only 500 million years after the Big Bang. The montage called the Hubble Legacy Field integrates inspection from 16 years' worth of Hubble Space Telescope profound field valuations involving the Extreme Deep Field Survey which provides the most penetrating view of the Universe.

The image offers astronomers the chance to study the oldest galaxies, giving them the ability to track the universe's expansion rate and, even more, the hidden chemical and physical factors that led to the growth of life on our home planet.

"Now that we have gone wider than in previous surveys, we are harvesting many more distant galaxies in the largest such dataset ever produced by Hubble", team leader Garth Illingworth, of the University of California, Santa Cruz (UCSC), said in a statement. In total, 7,500 separate exposures went into creating this first Hubble Legacy Field image.

But the new set of Hubble images, created from 7,500 individual exposures, is the most detailed Hubble photograph yet. Ground-based observations were unable to establish how galaxies formed and evolved in the early Universe.

"Just as ancient paintings can tell us about the period of history in which they were painted, so too can ancient galaxies tell us about the era of the Universe in which they existed", Hubble astronomers said. "Previously, most of these exposures had not been put together in a consistent way that can be used by any researcher".

Taking a look at the image you could see more than 13.3 billion years of the history of our Universe as 265,000 galaxies have been captured in it.

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.

Since then, astronauts have flown out to Hubble several times to make repairs, upgrade cameras, and install new hardware, improving the observatory's view of deep space. During this time, NASA's eye in the sky has continually astounded astronomers with incredible images of the cosmos. It also shows the faintest and farthest galaxies that can not be seen by the naked eye. "The Legacy Field is a pathfinder for WFIRST, which will capture an image that is 100 times larger than a typical Hubble photo".

The James Webb Space Telescope, which will give astronomers an even deeper look into the legacy field, is expected to launch in 2021.
