The year humans started to ruin the world

Geologists have determined the most powerful force on the planet.

Eric Roston   Astronomers have been telling us for nearly 500 years that humanity is not the most important thing in the universe. Evolutionary biologists established long ago that we're not even the greatest show on earth.

Spacecraft makes history arriving at one of the solar system’s last unexplored planets

NASA's Dawn spacecraft heads toward the dwarf planet Ceres in an artist's conception.

Rachel Feltman   The Dawn spacecraft is the first human-made object to visit a dwarf planet. Now it's time to look for evidence of liquid water.

Mars once had a sea larger than the Arctic ocean

An artist rendering of what recent research suggests Mars might have looked like around 4 billion years ago, when most researchers think the planet was considerably warmer than it is today.

Marc Kaufman   After six years of planetary observations, scientists at NASA say they have found convincing new evidence that ancient Mars had an ocean.

An artist's impression of a black hole.

Rachel Feltman   Some 12.8 billion light years away, astronomers have spotted an object of almost impossible brightness - the most luminous object ever seen in such ancient space.

First steps on Mars could be captured by Canberra's new satellite dish

Canberra's new $55 million DSS35 antenna is 34 metres in diameter. It could one day capture mankind's first steps on Mars.

Clare Sibthorpe   Humans could be walking on Mars in less than two decades and the giant leap for mankind may be captured first by Canberra's new $55 million space dish unveiled by NASA on Wednesday.

Jupiter begins its reign in the night sky
