The Hubble Space Telescope has captured stunning new views of Mars and Saturn in June and July. Hubble captured Mars on 18 July when the red planet was at a distance of 59.4 million kilometres (36.9 million miles) from Earth. The image clearly shows the on-going global dust storm that is obscuring the surface. Mars reaches opposition, lined up with Earth and the Sun, on July 27 and will reach its point of closest approach to Earth on July 31, providing the best view of the red planet since 2003. Saturn was imaged on June 6 when the ringed world was about 2.2 billion kilometres (1.4 billion miles) from Earth. Saturn reached opposition on 27 June.
Like graffiti sprayed by an unknown artist, unexplained narrow, arc-shaped, reddish streaks are visible on the surface of Saturn’s icy moon Tethys in new, enhanced-colour images from NASA’s Cassini spacecraft. The red arcs are among the most unusual colour features on Saturn’s moons to be revealed by Cassini’s cameras.
A new study has confirmed that Mars was once, billions of years ago, capable of storing water in lakes over an extended period of time. Using data from NASA’s Curiosity rover, the team behind Mars Science Laboratory has determined that, long ago, water helped deposit sediment into Gale Crater, where the rover landed on 6 August 2012.
