Two Moons in the Sky

This week, people might be able to see two moons in the sky, one of them is actually the planet Mars. As Mars and Earth reach their closest encounter in 60,000 years this week, the Hubble Space Telescope will be shooting pictures that scentists predict will be "spectacular". The first images showing surface details as small as 27 kilometres across, will be taken when Mars is 55.6 million kilometres from Earth.
