The telescope that will work as a time machine! When we say telescope everyone has this only picture in the mind – But telescopes are not only used on the earth, but in space too. In fact, we get a more clear and effective view of space when it’s taken from a space telescope than any telescope on the earth. This is one of the telescopes situated on the earth's surface. On the earth, we have a dense atmosphere with various components and gases as well as polluted air which blocks the view of outer space. The other problem is light pollution. Due to large cities and urban areas we have lots of bright light in the sky which makes celestial objects blur. So we didn’t get clear and exact images of the celestial object as it is. So, to solve this problem, many decades ago humans launched space telescopes that are orbiting the earth, outside its atmosphere. When we don’t have any light and air pollution we can easily get pictures of the stars and galaxies.
