The meltdown of Greenland's ice sheet is speeding up, satellite measurements show.

ice global warming climate change Greenland meltingSpace scientists say their discoveries about Saturn's moon Enceladus are stunning, if just a little baffling. Using the instrument-packed Cassini probe, they have confirmed that the 500km-wide world has an atmosphere. They have also seen a "hotspot" at the icy moon's south pole, which is riven with cracks dubbed "tiger stripes".

water ice Moon atmosphere Cassini Saturn Enceladus mirrorThe plumes of water that erupt from Saturn's icy satellite Enceladus can be traced back to a radioactive "meltdown" shortly after the moon formed. The discovery, in 2005, of water vapour spewing from geysers at Enceladus' south pole took scientists by surprise. How this tiny, ice-covered moon generated the amounts of heat needed to fuel these eruptions was a puzzle. Now scientists say a short-lived burst of...

water ice Moon Cassini Saturn Enceladus Voyager 2Scientists have produced a global geological map of Jupiter's moon Europa, which has been proposed as a destination for a future space mission. Interest in Europa has been fuelled by indications that a liquid water ocean lurks beneath its outer shell of ice. The mapping effort will help build a geological history of the enigmatic moon and target future explorations.

water ice Moon extraterrestrial life Jupiter Europa GalileoResearchers are testing technology that could allow a lander to melt through the ice crust of Jupiter's moon Europa to reach the water ocean beneath. Space scientists want to send a craft to the Jovian moon because its ocean might, in theory, harbour life. Once through the 10-30km ice sheet, the probe could take a sample of water, to analyse it for microbial life.

Arctic ice global warming North PoleGreenland's ice is melting rapidly. In some places, glacial levels have been falling by 10 metres a year and ultimately contributing to rising sea levels.

ice global warming Greenland vegetationScientists have reported worrying signs that the vast ice sheet over Greenland is melting. If the whole mass of ice disappeared, the world's sea level would rise by about six metres.

ice global warming Greenland meltingWhat he found was a protein that seemed to prevent ice crystals from growing. As studies of these intriguing "anti-freeze" proteins progressed, they were discovered in many more organisms - fish, insects, bacteria, fungi and plants that have to survive freezing temperatures. Many of our more hardy frost-surviving vegetables and even our humble lawns produce these ice structuring proteins when there is a harsh frost.
