Images of Earth, snapped by space probe Venus Express, failed to tell astronomers whether our planet had life.
      
      The research is conducted by means of VIRTIS spectrometer, a part of Venus Express, which has been launched to study Venusian environment in 2005. The aim of the project is to develop some techniques for detection of life on other planets.
      
      Images show our home planet to have the size of one pixel – this is how distant exo-planets usually look like in a telescope. VIRTIS spectrometer has detected water and oxygen, but scientists believe these data are not enough to tell whether the planet of interest is habitable. Therefore, scientists are waiting for more information to arrive – about photosynthetic processes, for instance.
      
      Venus Express is a joint project of scientists from many countries including Russia.
