Europe's new multi-billion-euro Sentinel programme has returned its first earthquake analysis.
The EU satellite system has pictured how the Earth moved when the Magnitude 6.0 tremor hit California's wine-producing Napa region last month.
Scientists will use the figure, called an interferogram, to trace precisely the extent of the fault rupture.
In the past, this type of analysis has been very time-consuming, but the Sentinel project will now ...
Who, What, Why: does limiting the power of appliances save energy?
The European Commission has banned the sale of powerful vacuum cleaners. Now it might do the same for other domestic appliances, but would this actually cut energy consumption?
It started with vacuum cleaners. Then there were howls of outrage when it emerged the European Commission has set up a working group to look at whether other common household appliances - kettles, toasters, bread makers ...
NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.
Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013.
"We think two big asteroids crashed into each other, creating a huge cloud of ...

Mounting evidence suggests Neanderthals were not the brutes they were characterised as decades ago.
But art, a high expression of abstract thought, was long considered to be the exclusive preserve of our own species.
The scattered candidates for artistic expression by Neanderthals have not met with universal acceptance.
However, the geometric pattern identified in Gibraltar, on the southern tip of Europe, was uncovered beneath undisturbed sediments that have also yielded ...
Given the option, would you want to think faster and have sharper attention? Research suggests that electrical brain stimulation kits could have just those effects. But now some companies are selling such devices online, leading to calls to regulate the technology.
It may sound too good to be true but scientists say the technology is promising.
Transcranial direct current stimulation (TDCS), which passes small electrical currents directly on to the scalp, stimulates the nerve cells ...
Scientists have finally solved the mystery of how rocks can move across the flat ground of a dry lake bed in Death Valley, California.
Visitors have long been puzzled by the sight of boulder tracks criss-crossing a dusty bowl known as the Racetrack Playa in Death Valley National Park. But two researchers now say the rocks - which can sometimes be heavy and large - are propelled along by thin, clear sheets of ice on ...
Astronomers have shown that dead stars known as white dwarfs can re-ignite and explode as supernovas.
The discovery appears to solve a mystery surrounding the nature of a particular category of stellar explosions known as Type Ia supernovas.
Theorists suspected that white dwarfs could explode due to a disruptive interaction with a companion star, but lacked definitive evidence until now.
Details of the research appear in the journal Nature.
The "smoking gun" in this case ...
