What did the Hubble Deep Field reveal to us about the origins of galaxies? It showed a large number of “mini-galaxies” which would eventually come together to form galaxies. Essentially every bright galaxy has a central supermassive black hole.
Q. What is the significance of the Hubble Deep Field images?
One of the main scientific justifications for building Hubble was to measure the size and age of the Universe and test theories about its origin. Images of faint galaxies give ‘fossil’ clues as to how the Universe looked in the remote past and how it may have evolved with time.

Q. What have we learned from the Hubble Extreme Deep Field?
Looking far away and far back in time, the Hubble Space Telescope found some ancestors of today’s galaxies. This Hubble picture reveals that star-forming galaxies were far more common in the clusters of the younger Universe than in modern clusters of galaxies near us today.
Q. Is it possible to travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Q. Is there a real picture of the Milky Way galaxy?
The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. We can only take pictures of the Milky Way from inside the galaxy, which means we don’t have an image of the Milky Way as a whole.
Q. How many black holes are in Milky Way?
Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone.
Q. How fast is the Milky Way moving through space?
1.3 million miles per hour
Q. Which arm of the Milky Way do we see?
Orion-Cygnus Arm
Q. At what speed does the Earth rotate?
roughly 1,000 miles per hour
Q. Can we see Earth rotation from space?
You don’t see the earth spinning from earth because it spins at 360 degrees per day. It’s just too slow for you to notice.
Q. How fast is our galaxy spinning?
130 miles per second
Q. Does the sun orbit a black hole?
The Sun, along with the rest of the hundreds of billions of stars that constitute the Milky Way, follows a complicated orbit determined by the combined gravitational field of all these stars. No, although its trajectory does take it around (at least) one black hole.
Q. Why don’t we feel the earth spinning?
Bottom line: We don’t feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.
