Question

Why was the Hubble Telescope put in space instead of on Earth? What kind of waves does the Hubble telescope look at? PLEASE ANSWER BEFORE MAY 26, 2017.

Answer 1

There are two essential factors that make a space telescope a good idea.

First of all, it gets above the atmosphere. This has the effect of removing three major obstacles to ground-based observation.

1: The weather. No cloud cover or rain can come over and ruin your observing session. The sky is always clear.

2: The sky itself. A telescope is useless during the day, as the rayleight scattering of sunlight that causes the sky to be blue blots out the stars entirely for many hours each day. The Hubble telescope is not restricted by day or night cycles.

3: The air causes distortion and so severely limits the resolution of any image obtained by looking through it. Getting above the air removes this distortion, allowing sharper images.

The second factor: it gets it off the ground. No matter where you put your telescope on the ground, it can only point at a given bit of sky as long as the Earth is turned towards it. If you put it in space it can aim at any point in the sky for hours or even days on end. Because the distances of the objects it is used to study are so vast, the fact that it is constantly moving around the Earth in its orbit makes no difference to the apparent positions of most things and hence it can sit and collect light from the same spot for a very long time, allowing incredibly faint and distant objects to be imaged.

An image like the Hubble deep field could never have been taken by a ground-based telescope. It took days of continuous exposure to collect enough light to make those distant galaxies visible. The Earth's rotation, the daylight, the weather, the atmospheric distortion would all have ruined it

Answer 2

So it has a closer look at stuff beyond this realm
