Computer chips of the size and sophistication required to meet the challenge already exist. ... For a planet like Mars, smart dust particles would each have to be the size of a grain of sand. ... Wireless networking would allow these particles to form swarms, and Dr Barker's team has carried out mathematical simulations to see how this would work. ... We envisage that most of the particles can only talk to their nearest neighbours but a...

Water was once widespread on Mars, data from a Nasa spacecraft shows, raising the prospect that the Red Planet could have supported life. ... Rocks of this age have largely been destroyed on Earth by plate tectonics. They are preserved on the Moon, but were never exposed to liquid water. So rocks containing phyllosilicates on Mars preserve a unique record of watery environments in the early Solar System, some of which could have been...

The dusty hoop lies some 13 million km (eight million miles) from the planet, about 50 times more distant than the other rings and in a different plane. ... Indeed, so feeble is the ring that scientists have calculated that if all the material were gathered up, it would fill a crater on Phoebe no more than a kilometre across.

Astronomers have confirmed that an exploding star spotted by Nasa's Swift satellite is the most distant cosmic object to be detected by telescopes. In the journal Nature, two teams of astronomers report their observations of a gamma-ray burst from a star that died 13.1 billion light-years away. The massive star died about 630 million years after the Big Bang...
