Previously it was thought that this area was completely devoid of galaxies and that only a few Milky Way stars were present. The original Deep Field discovered thousands of galaxies lying in this region of the sky.

Symbolically, Hubble’s deep field images demonstrate his best abilities.
The full UV-visible-IR combination of the Hubble eXtreme Deep Field; the biggest image ever released … [+] of the distant Universe. 5,500 galaxies have been identified in this small area of the sky; it would take 32 million of them to cover the ~ 40,000 square steps of all the space present.

By reappearing his “eye” on one region, he collects photons once and for all from the Universe.
The Hubble eXtreme Deep Field (XDF) has probably seen an area of sky just 1 / 32,000,000th of the … [+] total, but was able to discover about 5,500 galaxies inside: about 10% of the total number of galaxies in this slice in pencil style. The other 90% of galaxies are either too weak or too red or too dark for Hubble to reveal.

Through multi-wave observation, Hubble discovered thousands of objects farthest from Earth.
Galaxies identified in the eXtreme Deep Field image can be broken up into nearby, distant, and … [+] ultra-long components, with Hubble only displaying the galaxies that are able to be seen in its wavelength fields and at its optical boundaries. The decline in the number of galaxies seen at very great distances may reflect the limitations of our observers, since narrow, small, galaxies are not visible at high distances.

Looking at larger divisions, Hubble Frontier Fields ’campaign was highly variable.
The streaks and arcs present in Abell 370, a collection of distant galaxies of about 5-6 billion light years … [+] away, are some of the strongest evidence for gravity lens and dark case we have. The lens galleries are even further afield, with some making up the farthest galleries ever. This image was part of the Hubble Frontier Fields program.

The power of TESS and James Webb together reveals the most Moon-like locations to date, perhaps even in their star’s residential zone, while 30-meter telescopes are ground-based, Nancy’s Roman telescope (Formerly WFIRST), and perhaps the next generation a place – based observatory like LUVOIR or HabEx will need to discover what humanity has really been dreaming of for so long: an inhabited world outside our Solar System.

Formerly known as WFIRST, it is similar in size to Hubble, but with a broader view.
NASA’s Wide Area Infrared Telescope (WFIRST) has now been named Nancy Grace’s Roman Space … [+] Telescope, after NASA’s first Head of Astronomy. It is designed to produce wide-ranging and spectroscopic images of the infrared sky. One of the goals of the Roman Space Telescope is to look for clues about dark energy – the secret force that is accelerating the expansion of the universe. Another goal of the mission is to locate and study exoplanets.

The original Hubble Deep Field may have covered only a small area of the sky, but it taught us that there were at least hundreds of billions of galaxies within the visible Earth. Today, advanced data and analysis has put that figure closer to ~ 2 trillion. The sight of the Roman Nancy telescope will be about ~ 1000 times larger than the area of this part of Hubble’s deep image.
