Scientists are trying to find what exactly powers neutron stars` x-ray superbursts.
Scientists were pretty sure until now that they knew how the surface of a neutron star - a super dense star that forms when a large star explodes and its core collapses into itself - can heat itself up.
Unlike elements like carbon or iron, gold cannot be created within a star instead it can only be formed by a cataclysmic event.
A study led by the University of Alicante has detected what may be the first observational evidence of existence of a new exotic phase of matter in the inner crust of neutron stars (pulsars).
A major campaign using NASA`s Chandra X-ray Observatory and several other satellites has suggested that exotic neutron stars, magnetars may be more diverse-and common-than previously thought.
Pulsars are perhaps the most extraordinary physics laboratories in the Universe.
Scientists have discovered dramatic flares and bursts of energy emanating from a rotating pulsar.
