Gravity Waves. Albert Einstein predicted their discovery as part of his general theory of relativity.

A $300 million project called LIGO gets switched on in July. It consists of a wave antenna in two halves, one in New York and one in Livingston, La. A gravity wave is kind of like a space-quake, and will detect if a supernova occurs in our region. Or something undiscovered and just as dangerous?

Geomagnetic Field. SWARM is four satellites in two different polar orbits between 400 and 550 km altitude, which will make a global high-precision survey of the geomagnetic field. This will help scientists study the scary aspect of a magnetic pole shift.
