Scientists have announced the discovery of a sub-atomic particle consistent with the Higgs Boson.

The discovery of the boson, also known as the God particle, comes after its existence was first theorised in the 60s.

"We have observed a new boson," said Joe Incandela, spokesperson for one of two CERN labs working on the quest for the Higgs, the particle that is believed to explain the mystery of mass.

There's a roughly one in 3.5 million chance that the scientists would get this result if the particle didn't exist, Mashable reported.

"A more complete picture of today's observations will emerge later this year after the LHC provides the experiments with more data," Fermilab said in a press release.
