The Plan­ets

The Western Star - - Tv Guide Life -

Sun­day, abc, 7.40pm

English pro­fes­sor Brian Cox (pic­tured) is a nat­u­ral sto­ry­teller, which is a win­ner for view­ers of his doc­u­men­taries – he really does make ed­u­ca­tional top­ics fu n . As Cox con­tin­ues his tour of the so­lar sys­tem with The Two Sis­ters – Earth and Mars, he re­veals that it was once home to not one, but two blue plan­ets. The story he tells sounds like a fairy­tale – two sis­ters, alike in many ways, take dif­fer­ent paths, but while one flour­ishes, the other dies. The sis­ters in ques­tion are, of course, Earth and Mars. To­day, Mars is an arid desert world, but it did have the same po­ten­tial as Earth. Which begs a big ques­tion – was there once life on Mars?
