berdebutelah star system confusing astronomers.
New observations will be undertaken of the Hubble telescope reveals the planet Fomalhaut b orbits eccentric who have extreme system, the planets orbiting the nearest and farthest from the star and seems to cross a minefield large and dusty debris. "We were very surprised.'s Not what we expect, "said study leader Paul Kalas, an astronomer at the University of California at Berkeley and the SETI Institute in Mountain View, California, said in a statement on Tuesday (Jan. 8).

Fomalhaut b is a giant alien planet that is almost three times the mass of Jupiter. It was the first alien planet ever imaged directly in the light of this tampak.Planet orbiting dust that surrounds the star Fomalhaut and is located about 25 light-years away in the constellation Piscis Austrinus.
In October, the scientists dubbed this planet as a 'zombie planet' because it seems to rise from kubur.Pertama this planet was discovered in 2008, further research suggests the planet is nothing more than a cloud of dust besar.Pada in 2012, astronomers raise Fomalhaut planet status b when new observations prove an object resembling planets embedded in a cloud of dust that float freely.
Recent observations from this strange planet system mengungkapkanbahwa dusty debris disk around the star Fomalhaut wider than expected sebelumnya.Sabuk this debris has a wide area about 14 billion and 20 billion miles around the star.
Another oddity, Planet orbiting Fomalhaut b seems closer spacing 4.6 billion miles (7.4 billion km) from the star at the nearest point and farthest point about 27 billion miles (43.4 billion km) as it orbits.
Planet Fomalhaut b orbits its star for 2000 years by crashing debris located around the disc, said ilmuwan.Penelitian was announced on Tuesday at the 221st meeting of the American Astronomical Society in Long Beach, California.
A hidden planet around Fomalhaut?
Among several theories to explain the extreme orbits Fomalhaut b is the possibility that this exoplanet has met with other planets, his neighbor who has not been found.

"Hot Jupiters can throw other planets through scattering events, where an incoming planet and other planets thrown out" said Mark Clampin, of NASA's Goddard Space Flight Center in Greenbelt, Md., said in a statement. "" It could be a planet to be discarded. "
Images from the Hubble telescope reveals a clear gap in the dust and debris around Fomalhaut ice, the area that can be swept away by the presence of planets, researchers said.
Another theory suggests that Fomalhaut b could never have a dwarf planet as a neighbor, but the giant planets destroy a small planet in a disaster tabrakan.Kecelakaan that this could explain why the star Fomalhaut has a narrow debris outside of the disc that has the age of 10,000 years, said researchers.
Is Fomalhaut b has a ring?
Another interesting theory of planet Fomalhaut is probably the planet has rings like Saturn planet and is destined to experience a spectacular crash when through the debris in orbit around the star Fomalhaut in 2032.
A ring of dust and ice could explain why Fomalhaut b appears so bright in visible light images, but relatively faint in the infrared light. Or dust ring around the planet will reflect the light, making it appear brighter planet. But the dust clouds can also have an impact on the moon at around Fomalhaut b, if they had a satellite, the researchers said.
In 2032, astronomers hope to solve the puzzle that makes puzzled scientists since discovered planet Fomalhaut b.
Are these exoplanets are in the field the rest of the debris in the disk or not?
If the planet is in the rest of the debris disk, the planet will be bombarded with dust and ice in the year 2032 when the planet's orbit through terjauhnya.Dan it would make the planet in infrared light increases brightness, tambahnya.Dampak of this debris can creating a light show in the sky of the planet as it did in the planet Jupiter when comet Shoemaker-Levy 9 hit in 1994.
If Fomalhaut b is not in the same plane with the debris disk, then it will gradually dim as the planet away from its star, the researchers said.
Hubble telescope officials say the astronomers plan to continue to monitor the Fomalhaut star system for several years and decades ahead to see how the change of the system from time to time.
