It is so dense that a teaspoonful would weigh the equivalent of a mountain.
The star, named PSR J1824-2452I, shifts backwards and forwards between emitting X-rays and radio waves. This 'switch' is caused by the rise and fall of gas streaming onto the pulsar from a companion star,according to Nasa.

It was discovered by astronomers using a fleet of orbiting X-ray telescopes, including NASA's Swift and Chandra X-ray Observatory.
The European Space Agency International Gamma-Ray Astrophysics Laboratory detected a flash of X-rays on 28 March this year. The pulsar was observed by Swift's X-Ray telescope the following day.
