Galaxies. Billions OF billions of galaxies. To quote Isaac Asimov; "The Stars, Like Dust..."
Hubble Deep Field was created in 1995.
Hubble Deep Field South was created in 1998.
The Hubble telescope looked deep into space and discovered the Galaxy field. When then realised that it is obvious we are not alone.
Hubble's law is a law relating to objects in deep space that is named after Edwin Hubble, who helped verify its existence. Hubble's law states that objects in deep space are observed from Earth to have a radial velocity, measured by the Doppler shift in their spectra, which is proportional to their distance from us. In simpler, less quantitative words: Everything in the universe is moving away from us, and the farther it already is from us, the faster it's moving away from us.

Galaxies. Billions OF billions of galaxies. To quote Isaac Asimov; "The Stars, Like Dust..."
Hubble Deep Field was created in 1995.
There are at least 3000 galaxies in the Hubble Deep Field North (with billions of stars, planets, and moons in each one; as well as asteroids and nebulae). Their light has taken 13 billion years to reach Earth.
Hubble Ultra-Deep Field was created in 2004.
Hubble Deep Field South was created in 1998.
The Hubble Ultra Deep Field is a million second exposure into an area of the universe revealing numerous galaxies as far away as 13.7 billion light-years. By our reckoning, it is within a few hundred million years of the origins of the universe. But since the light took that long to get here, we have very little idea where the galaxies actually are right now in time.
Yes, and better than ever. Google "Hubble Ultra Deep Field" for some of the most amazing pictures you will ever see. Thousands upon thousands of galaxies.
It would take at least 1,000,000 years for the Hubble Space Telescope to observe over the entire sky of 100 billion galaxies in the universe.
The point of the Hubble Deep Field observations is that scientists pointed the Hubble Space Telescope toward a dark patch of the sky where there were no known stars or galaxies. Everything observed in those photos had been entirely unknown before the images were obtained. So, nothing there has a "name"; by now, it probably has an index number in some database. But not a "name".
