Earth-like the other solar system might be quite common in the universe, as suggested by the study.
A graduate student of geochemistry and astrophysics came out with a new method to evaluate the geochemistry of planets outside our solar system for the study, and it was published in the journal Science this week.
A probability has been raised that many rocky planets are like the Earth, there are many large numbers of rocky planets in the universe.
Doyle evaluated the elements in rocks from asteroids or rocky planet fragments, encircling the six white dwarf stars. Observing a white dwarf is like doing a dissection on the contents of what it might have gathered in its solar system.
The researchers studied about the six most common elements present in rock: iron, oxygen, silicon, magnesium, calcium, and aluminum.
Doyle said, that the rocks they evaluated when compared to rocks from Earth and Mars.
When evaluated they are Earth-like and Mars-like in terms of their oxidized iron.
Since the scientists were unable to study actual rocks from white dwarfs, the scientists used calculations and formulas. The evaluated data were collected by telescopes.
If the space inhabitant rocks have a similar quantity of oxidation as that of Earth has, then it can end up that the planet has similar tectonics plate and similar potential for magnetic fields as the Earth, may be widely believed as to be key ingredients for life, co-author Hilke Schlichting said, the associate professor of astrophysics and planetary science of UCLA. This study is a surge forward in being able to make this conjecture for bodies outside our own solar system and indicated it would be very likely because there are truly Earth analogs.
