Earth-like exoplanets are fairly common, according to a new UCLA study.
Scientists led by Alexandra Doyle, a graduate of the University of California at Los Angeles (UCLA) for Geochemistry and Astrochemistry, came up with the idea A new method for analyzing the geochemistry of planets outside our solar system for the study, this week published in the journal Science.
"We have just increased the likelihood that many rocky planets are like the Earth, and there is a very large number of rocky planets in the universe," said co-author Edward Young, a professor of geochemistry and cosmochemistry at the University of California UCLA.
Doyle analyzed the elements in rocks of asteroids or rocky planetary fragments and circled six white dwarf stars.

"Observing a white dwarf is like an autopsy of the contents of what he devoured in his solar system," she said.
The researchers studied the six most common elements in rocks: iron, oxygen, silicon, magnesium, calcium and aluminum.
"Very similar," Doyle said regarding the rocks they analyzed compared to rocks from Earth and Mars.
"They are earth-like and march-like." We find that rocks everywhere are rocks with very similar geophysics and geochemistry.

"If extraterrestrial rocks have a similar amount of oxidation as the Earth, one can assume that the planet has a similar plate tectonics and a similar potential for Magnetic fields such as Earth's which are widespread are considered vital, "said co-author Hilke Schlichting, associate professor of astrophysics and planetology at UCLA." This study is a leap forward to drawing these conclusions for bodies outside our own solar system and shows that there are likely to be real Earth analogues. " GET THE FOX NEWS APP
