New Planet That Resembles Earth
The discovery of "the world tirta new" (Earth-like planets are abundant water) that is orbiting a star 40 light-years away within the first planet known to be similar to Earth and make men become close enough to be able to sniff the atmosphere, astronomers said as quoted by the journal Nature.
Named GJ 1214b, the size of the planet is only about 2.7 times the size of planet Earth with a mass about 6.5 times heavier than Earth.
Based on its density, the scientists thought that GJ 1214b contains three quarters of liquid water with a solid core of iron and nickel and hydrogen and helium atmosphere that is similar to Earth.
But in many other ways, this planet is "cruel beast very different" from the Earth in which we live, the scientists said.
"Basically this is a vast ocean," said lead researcher David Charbonneau of the Smithsonian Center for Astrophysics, Harvard University, Cambridge, Massachusetts.
"(On the planet) no single continent floating on top or burst of water."
More than that, GJ 1214b is hotter than Earth and its atmosphere ten times thicker than our planet, researchers said.
This may make it difficult to live like any so far we know. For beginners, the atmospheric pressure on the planet's surface is enormous and very little light penetrates fog difficult to achieve the ocean planet.
New planet like Earth is still very foreign.
Super-Earth planet was discovered using the MEarth project, one unit of device-based small telescopes on Earth that are used to detect changes from minute to minute of the power of their light dim red nan called M dwarfs (dwarf).
Periodic flicker could starlight caused by planets transiting separately or circling stars. Because the dwarf M dwarfs more opaque than stars like the Sun, then it becomes easier planted on light power reduction caused by Earth-sized planets smaller mass.
Although GJ 1214b is not directly visible, definite changes in starlight as traces his journey, allowing astronomers to measure the size and mass of the planet, which will offer clues to the planet's composition.
And because it's so close to the Earth tirta, thus Charbonneau, optical telescopes based in space like Hubble or Kepler can be used to sniff all day definite chemical constituents of the Earth-like planet's atmosphere.
"A light from penetrating the dwarf planet similar to Earth's atmosphere (such as sunlight through the Earth), and stick to the features of atoms and molecules what is," said Charbonneau.
Overall, this discovery was a "landmark achievement" that could close the gap in planetary science, said Greg Laughlin, astrophysicist at the University of California, Santa Cruz, who was not involved in the study.
"I always imagine what kind of shape the planet six times the mass of the Earth. Now we know. The planet is actually very different from our solar system, "said Laughlin. (*)
