London, July 20 : An asteroid may have flipped Mars’ magnetic field on and off like a light switch around 4 billion years ago, says a group of scientists researching on the Red Planet.

The scientists have said that Mars once had a magnetic field that could have been set in action by a dynamo created from the convection of material in the core, much like the Earth''s core.

However, according to crater records, it is believed that the Martian dynamo ceased in a short time of almost a few tens of thousands of years, a phenomenon that has not been explained by researchers as yet.

London, July 20 : The Large Hadron Collider, which is being built by the European Organization for nuclear research (CERN) in a tunnel below the French-Swiss border near Geneva, Switzerland, is entering the final stages of being lowered to a temperature of 1.9 Kelvin (-271 degree Celsius), which is colder than deep space.

The most powerful physics experiment ever built, the LHC will re-create the conditions just after the Big Bang. It will search for the Higgs boson - the so-called "God particle".

According to a report by BBC News, currently, six out of the LHC''s eight sectors are between 4.5 and 1.9 Kelvin, though all sectors of the machine have been down to 1.9 Kelvin at some stage over the last few months.
