Researchers at Imperial College London have just begun a 5-year project to design and build tiny earthquake measuring devices to go to Mars on the 2007 NetLander mission.

Unlike the instruments on next year`s European Mars Express/Beagle II mission, the Marsquake sensors will be the first to look deep inside the planet.
The internal structure of Mars is a key to understanding some fundamental questions about the planet including whether life ever existed there.
The sensors are capable of detecting liquid water reservoirs hidden below the surface, where life could possibly survive on Mars today. The recent discovery by the Mars Odyssey orbiter of large amounts of ice at the poles opens up the possibility of liquid water existing in the warmer conditions underground near the Martian equator.

A stellar flare 10 times more powerful than anything seen on our sun has burst from an ultracool star almost the same size as Jupiter
A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
