Gdansk, Poland (TVN/CNN) - One of the most accurate clocks in the world has been built in Gdansk.

The clock mechanism operates based on impulses sent by pulsars - neutron stars, which radiate with exceptional regularity.

Construction works started on the occasion of the 400th anniversary of the birth of Gdansk astronomer Johannes Hevelius, the Polish astronomer who built a prototype pendulum clock.

The initiators were the Pomeranian Special Economic Zone and Gdansk Science and Technology Park.

The clock works in a completely different way than previously known timers. Mechanism based on an astronomical antenna aimed at the pulsar will process its impulses into the units of time. Pulsars are neutron stars with very high density and high rotation speed.

For example, an object with a mass the Sun would have a diameter of 10 km. Pulsars' radiation reaches the Earth in the form of regular radio "flashes."

The world's most accurate timer has been installed in St. Catherine church in Gdansk, the patron of science, where Johannes Hevelius is buried.
