Is there life on other planets?

              The question whether there is life on planets other than the Earth has often perplexed scientists. If it is true that there is life on planets other than the Earth, what could be the possible ways of establishing contact with the living beings of other planets?

               It is felt that only radio can help to solve this problem. In 1960 American scientists received radio signals from some stars that created a hope about the existence of life on some other heavenly bodies. However, they could not get any concrete evidence to prove this.

                     A few years ago, people talked of having seen some unidentified flying objects (UFO’S) in the sky at many places. It was observed that the flying objects were shaped like saucers. People called them flying saucers. This led scientists to think of the possibility of life on other planets as well. It was felt that these saucers were extra-terrestrial attempts at scientific experiments. These saucers had different shapes. Some of them were round while others were cigar shaped. Many stories were heard about their colours. Their speed was reported to be very high.

                  These flying saucers have also been photographed. They were even chased by aeroplanes. A thorough study of these objects revealed that the so-called flying saucers were either balloons launched for weather studies or some meteoric bodies. Now scientists are of the view that the Earth is the only planet which has favourable conditions for the existence of life. Scientists have not found any other planet in the universe where there is life.
