Of the solar system around the star Beta Pictoris was a relatively pleasant place, with a huge planet, scientists have come to the view, and a huge amount of debris flying around. However, it has become even more compelling.
That is, as the astronomers now think they have to be picked up for a second planet in orbit around a star. The discovery is based on more than 10 years of data on tiny changes in the star to the orbit caused by the attraction of the star, and some scientists now believe that it is a planet.
The Beta Pictoris solar system, it is a special one for scientists because it is relatively close to the Earth, it is only 63.4 light-years away and relatively young, about 23 million years ago. This means that science research is to gain a better understanding of the turmoil of adolescence, the development of solar energy systems.

What the scientists knew about it before the review, the Beta Pictoris’ stage already looked quite a mess.
A disk of planetary debris to debris, the outer regions of the solar system; astronomers think that the teens of rock called planetesimals ricocheting into each other, it remains that debris. Which planetesimals enter the solar system 50 astronomical units (or AU, the average distance between the Earth and the sun, at a distance from Beta Pictoris to be 100 AU. One AU is about 93 million miles or 150 million kilometers.
About a decade ago, astronomers determined that it was a large planet, out of the nine to 13 times more massive than Jupiter, and is called Beta Pictoris b, orbits about 9 AU from the star. Unusual, for they, it has been shown; most of the worlds have been identified as being in the shadows, who is a star on the disc, or slight variations in the roof top. And scientists have even been spotted on the exocomets of zig-zag all over the Beta-Pictoris system, and slowly lose steam as they go.
However, astronomers combing through a 10-year period, the data collected by the European Southern Observatory’s High Accuracy Radial Velocity Planet Searcher (HARPS) program, and realized that what they knew about the Beta Pictoris solar system, still do not quite add up.
The HARP measures tiny changes in a star’s light, caused by tiny movements of the stars, as if the force of gravity in conjunction with that of the planet. For a star like Beta Pictoris, which frequently grows and shrinks, these small changes are very difficult to derive from these pulses, but that’s exactly what the team behind the new research.
The astronomers had, for the signals which they believe can only be explained by a second planet, which is about nine times the mass of Jupiter and orbits its star once every 1200 or so days. The planet is about 2.7 AU away from its star, which is equal to the distance from our sun to the asteroid belt.
The researchers said that they hope that other technologies will be in a position to be able to spot the planet, called Beta Pictoris, c, as well. This planet is directly between the star and the Earth, which means that the scientists were able to study the world, its atmosphere, and all of the rings and the moons that orbit. When these waves allow astronomers to directly image Beta Pictoris, c, as its neighbour, they may also be able to answer questions about how planets are formed.
The research is described in a paper published Monday, Aug. 19) in the journal Nature.
