universe is expanding
Edwin Hubble didn't discover redshift. What he did was make a systematic statistic of redshifts and blueshifts, of known galaxies. What this demonstrated was that the Universe is expanding.

Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.
That they are all moving away from each other at a great rate of speed and that speed seems to be acceleration.

In the centre of the Milky Way.

The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.

Hubble did not discover that there were other galaxies; that had been discovered earlier. But Hubble was the first to demonstrate that the more distant another galaxy is, the faster it is moving away from us. Edit: I'm not sure that's right. Hubble was surely the first to prove that a "spiral nebula" was too far away to be in the Milky Way. That nebula is what we now call the "Andromeda galaxy". I know that Slipher and others did important earlier work on red shifts, but I'm pretty sure Hubble did discover that other galaxies existed.
Edwin Hubble did not think of making the Hubble Space Telescope. The Hubble space telescope is simply named after him because of his contributions to astronomy. His greatest discovery came in 1929 when he determined that the Universe was expanding, which later became the bases for the Big Bang theory.
Galaxies are moving away from each other in a constantly expanding universe.

It was named after the famous scientist Edwin P. Hubble (1889-1953) because he was the one who made the discovery that our universe was expanding. The space telescope designed to replace Hubble around 2018 is named for the late NASA administrator James Webb (1906-1992).
