Secrets of the Universe. Planet Earth – oasis in space:

Far away, in the hidden depths of space, the planets are so amazing that their descriptions are not even in science fiction. For the first time in history, scientists are discovering alien worlds outside the solar system. Spaces where the ice is hot and the rains are iron, they are not on the map, they are mysterious and unpredictable. Scientists are striving for the greatest discovery: to find, hidden somewhere among the unknown worlds of the planet, similar to ours. The secrets of similar exotic planets await their discovery across the galaxy. But astronomers will not rest until they find the holy grail – a planet similar to ours, capable of supporting life, another Earth.
