Interesting Planet

One day I saw a rainbow and it was from my 1-2 km away. I went it and I passed under the rainbow. Then a the gate of the planet has been opened. This planet was like its size was between moon and earth. This planet has source of life. Astronauts went this planet and they came from earth then they brought some piece of then planet. Researchers searched inside it and it has a bad bacterias. Then researchers throw that piece from space. Then astronauts went again and they brought a piece of planet researchers searched inside it. This time it has good bacterias but researchers didn’t understand how could it be first bad second good. They tought and they found a idea. Their idea was this planet was new because of it has bad bacterias and planet repel bacterias later then this planet was so clean. Then astronauts and researchers be relaxed for it.
