The new planet is much more solid than ever found during this and consists almost entirely of carbon. Because the density is very high, scientists calculated that the carbon would have had kristalisation, so most of the planet should have a gem.


"The history of evolution and the incredible density of the planet indicates that it consists of carbon, a neutron star orbiting the giant gem every two hours in the trajectory of a very small," said Matthew Bailes of Swinburne University of Technology, Melbourne.

Located 4000 light years from Earth, or about 1 / 8 distance from Earth to the center of the Milky Way Galaxy, the planet probably is the remnant debris from a massive star that lost its outer layers being pulled by a pulsar star in its orbit.

Star pulsar is a small star, formed from the neutron star that has died, and its size is only about 20 kilometers but it spins very quickly to hundreds of times per second. Very rapid rotation that produces waves of radiation that was brought out.

Pulsar is a stellar example of J1719-1438, where the radiation is flung always sweep the Earth's surface and have been monitored with telescopes in Australia, England and Hawaii. Astronomers detected the waves emitted by this star due to the gravitational pull of planets orbiting the star.


This lead the researchers to conclude that planets orbiting a pulsar star within just 2 hours and 10 minutes, has a size slightly larger than Jupiter but has a density of up to 20 times.

But unlike Jupiter which is a gaseous planet, the high density makes elements such as hydrogen and helium are very few on the planet. Hydrogen and helium are the main elements of planet-forming gas.

In addition to carbon, this new planet also appears to contain little oxygen at the surface, and thinned at the center that contains carbon.



What kind of a way this gem planet seen up close, remains a mystery.

"What does that planet, I still can not speculate," said Ben Stapper from the University of Manchester. "But I'm sure we did not find a picture of something shiny."
