Why is there no life on the other planets?

As far as we know, there is no form life on any of the other planets in the Solar system.

It was assumed that light, water and oxygen- at seen at the earth’s surface- were necessary to life and we know that none of the other planets have these surface conditions. However, in the last few years it has been found that some life- forms need neither light nor oxygen as thy live in a system which depends on sulphur from deep undersea volcanoes in conditions of extreme heat and pressure. So some scientist hope that life- from might exist in similar extreme conditions elsewhere in the Solar system.

Other possibilities that are being explored (or may be explored in the future) include Saturn’s satellite Titan and Jupiter’s satellite Europa, as well as several comets to see if they contain the basic materials to support life.
