Scientists have discovered a star with a double gas ring.

<P> Nishi-Harima Observatory, Hyogo, Japan, 19 reported that the Observatory, the researchers observed Pleiades star surrounded by the size of the two gas rings. .If the observations are confirmed, this will be the first discovered around a star with two rings. .</ P> <P> Pleiades star called by second, also known as the Taurus 28, is about 400 light years from Earth, the Pleiades. .It is the Pleiades can be observed by the naked eye within the seven stars in the darkest of the five other stars, the sun's diameter is about 4 times. .</ P> <P> Nishi-Harima Observatory, the researchers used the largest reflecting telescope in Japan the Pleiades by-second observations, and the light from the spectral analysis, found that the ring of gas around a star inside of the original students have become .not previously been observed in a small circle. .This small ring is also hydrogen by high temperature gas composition, and large ring plane angle of 60 degrees. .</ P> <P> 2004 年 12 months, a researcher at the Observatory, the star has been observed, but it was only to see a ring. .Scientists speculate that the formation of the new ring time soon, it might be the glow from the fall of 2005 for the first time to reach the Earth. .</ P> <P> now, scientists still can not clearly explain why the stars will appear around the ring of gas composition, the mainstream view is that hydrogen gas emitted from the stellar surface the rotation of the stars eventually evolve into the ring. .Associate Professor, National Astronomical Observatory of Japan, Junichi Watanabe said, scientists have always thought that if there is gas around a star formation around the ring, usually only one, if confirmed by the Pleiades second ring has two overlapping, would be a major discovery .. .</ P> </ p>.
