Discovered a new type of planet:
These mysterious heavenly bodies with high density observed outside the solar system, may be remnants of ice giant planets that come too close to their suns and have suffered colossal TEMPERATURE their effects, shows a new study of exoplanets.
Among the most surprising discoveries made in the NASA Kepler mission (for the study of exo-planets) are a special type of spatial objects, unusually heavy for their size. Results FST present at a conference on exo-planets, held at the Royal Society of London.
In some cases, astronomers were able to estimate the mass and dimensions planned that some of these planets were close to the radius of the Earth, but unusually high density - higher than pure iron.
None of the currently accepted theories of planetary formation can not explain the formation of these extremely dense celestial bodies.
Olivier Grasset, a geophysicist at the University of Nantes, France, believed that these objects could be "nuclei fossils" of some planets that were once much larger - an idea proposed for the first time in 2011.
