An unusual signal picked up by a European space observatory could be the first 
direct detection of dark matter particles, astronomers say.

 

 

 

 Dark matter cannot be seen, but the mysterious substance is thought to make up 
around 85% of all the matter in the universe. The web of dark matter that 
stretches through space is believed to give the cosmos its structure, although 
so far it has eluded direct detection by physicists.
 Researchers at Leicester University spotted the curious signal in 15 years of 
measurements taken by the European Space Agency’s orbiting XMM-Newton 
http://xmm.esac.esa.int/ observatory. They noticed that the intensity of x-rays 
recorded by the spacecraft rose around 10% whenever it observed the boundary of 
Earth’s magnetic field that faces towards the sun.
 The findings are tentative and could take several years to check, but if 
confirmed they would represent a dramatic advance in scientists’ understanding 
of the universe.
