New Horizons sees Pluto’s close approach hemisphere and Charon’s ‘dark pole’
NASA’s New Horizons spacecraft doesn’t pass Pluto until July 14th — zipping by about 7,800 miles (12,500 kilometres) above the surface of the dwarf planet after a journey of almost 3 billion miles — but the mission team is making tantalising new discoveries as the piano-sized probe bears down on the Pluto system.
The mysterious ‘lakes’ on Saturn’s moon Titan
Titan is home to seas and lakes filled with liquid hydrocarbons, but what forms the depressions on the surface? A new study using data from the joint NASA and European Space Agency (ESA) Cassini mission suggests the moon’s surface dissolves in a process that’s similar to the creation of sinkholes on Earth.
Hot lava flows discovered on Venus
The European Space Agency’s Venus Express spacecraft has found the best evidence yet for active volcanism on Earth’s neighbour planet. Seeing the planet’s surface is extremely difficult due to its thick atmosphere, but radar observations by previous missions to Venus have revealed it as a world covered in volcanoes and ancient lava flows.
Brightest early galaxy likely to contain first generation stars discovered
Astronomers using the several of the largest telescopes on Earth and in space have discovered CR7, a galaxy three times brighter than the brightest distant galaxy in the early universe known up to now. The scientists also found strong evidence that examples of the first generation of stars lurk within it.
