#10 – Water on Mars
A team of researchers has shown that at least one-fifth of the red planet was completely covered with a true H2O. All signs of life, which certainly existed in the ocean can be found deep in the sands of Mars. Recently liquid water was found on Mars. If there is water, so maybe there is life as well.
#9 – Footprints in the Sand
Two years ago, Curiosity probe found traces of nitrogen, hydrogen, oxygen, phosphorus and carbon under the surface of Mars. In 2014 NASA published a report which indicates the presence of organic compounds found by the probe. All this shows that most likely life was on Mars.
#8 – Asteroids And Comets
Scientists believe asteroids and comets are key factor of the emergence of life on our planet. In particular, the comet, according to the report published in August, brought to Earth amino acids, without which the development of all organisms would be impossible. Taking into account the abundance of comets in space, most likely they can do the same for another planet.
#7 – Jupiter's Moon
The tiny moon of Jupiter, Europa, is covered with large faults. Astronomers believe that it is an indicator of the places where the water went into the crust of the satellite. That's why NASA is investing hundreds of millions of dollars in projects of future missions, hoping to discover life beneath the surface of Europe.

#6 – Saturn's Moon
The same outlook Enceladus has - scientists have confirmed that under the icy shell of this giant ocean is hidden. If this is true, then Enceladus is the ideal place for the development of life.
