Our earth in the Universe

Wonders all around:
many natural phenomena occurring in the depths of outer space and on the earth fascinate us. Red, glowing lava streams erupt from volcanoes. Earthquakes make the ground tremble and shake. Cyclones sweep over oceans and land, causing untold suffering to human beings and animals. The Earth is the only planet in out solar system that has life on it .We have not yet visited the other planets but have sent remote-controlled probes to explore them. These probes have radioed back pictures o these planets to us. Our solar system is a small part of the milky way,which ,in turn, is a small part of a much larger universe!
