Science has made it possible for us to develop technology to look at
our home planet from afar, in space. These satellite pictures show us
different views, snapshots of goings on here ... some natural, some
cultural (i.e., human-caused).
Ice islands in the Atlantic, blocked river valleys in Pakistan and
salt lakes in the outback were among the images captured by the
European Space Agency and Nasa satellites last month
