What is the size of the Hubble Space Telescope?
Hubble’s primary mirror is 2.4 meters (7 feet, 10.5 inches) across. It was so finely polished that if you scaled it to be the diameter of the Earth, you would not find a bump more than 6 inches tall. Hubble is 13.3 meters (43.5 feet) long — the length of a large school bus.
How does the Hubble space telescope work?
Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can see space better than telescopes on Earth can. Hubble is not the kind of telescope that you look through with your eye. Then Hubble uses radio waves to send the pictures through the air back to Earth.

Is the Hubble telescope reflecting or refracting?
Hubble is a Cassegrain reflector telescope. Light from celestial objects travels down a tube, is collected by a bowl-like, inwardly curved primary mirror and reflected toward a smaller, dome-shaped, outwardly curved secondary mirror.

Why can’t we see the sun in space?
If you mean why can’t you see the illumination from the sun if you’re not looking at it that’s because there’s no atmosphere in space to scatter the light. Yes sun is visible in other planets but like earth. As on earth it is visible after ~12 hrs.

Can humans 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.
