The Sky at Night - Venus, Earths Twin
Venus, Earths Twin How can two such similar planets have become so different? One is the crucible of life, the other an inferno with a surface scorched by raining acid, yet both began as almost identical bodies. With Venus prominent in the sky in May, the team explores our nearest neighbour, discovering how it formed and how ESA's Venus Express spacecraft has revealed the secrets of its atmosphere. Dr Lucie Green explores what happened to leave Venus with searing temperatures and acid rain, and talks to Climate expert Dr Hugo Lambert about whether it could happened to Earth.
