A device to detect neutrinos has been developed entirely by South Korean technology.

Researchers at a dozen South Korean universities including Professor Kim Su-bong's team at Seoul National University say that they have installed two neutrino detectors at the nuclear power plant in Yeonggwang, South Jeolla Province. The installment took five years and researchers are now ready to begin experiments from July.

Neutrinos, which are emmitted by the sun, are extremely light and move at the speed of light and are thus called "ghost particles." Scientists believe that once the traits of neutrinos are cracked, it will lead to discovering the secret to the birth of the universe.

The researchers say that France and China are building similar detectors but that Korea’s is the first to reach completion.
