There's no denying the fact that Earth is the only habitable planet and one of its kind, but according to new evidence there may be numerous Earth-like planets in the universe!Researchers presented the findings in a new study published in the journal 'Science'."We have just raised the probability that many rocky planets are like the Earth, and there's a very large number of rocky planets in the universe," said co-author Edward Young, UCLA professor of geochemistry and cosmochemistry.Led by Alexandra Doyle, a UCLA graduate student of geochemistry and astrochemistry, scientists developed a new method to analyze the elements in rocks from asteroids or rocky planet fragments that orbited six white dwarf stars.White dwarf stars are dense, burned-out remnants of normal stars. Their strong gravitational pull causes heavy elements like carbon, oxygen and nitrogen to sink rapidly into their interiors, where the heavy elements cannot be detected by telescopes.The closest white dwarf star Doyle .
