A Saturn like planet found

Researchers have detected what appears to be a Saturn-like planet residing near the Milky Way galaxy’s bulge. The newly discovered exo-planet (or extrasolar planet is a planet that orbits a star other than the Sun). This planet recorded has a mass somewhere between Saturn and Jupiter and orbits a star with half the mass of the Sun, says, scientists.

An international team of researchers, led by Aparna Bhattacharyaha from the University of Notre Dame in the US, used the gravitational microlensing method to detect a gas giant planet orbiting the lens stars of a microlensing event.

This gravity lens, discovered in August 2014, was designated at OGLE-2014-BLG-1760 and is the 1,760th microlensing event detected by the Optical Gravitational Lensing Experiment (OGLE) collaboration, said, researchers. OGLE is a Polish astronomical project based at the University of Warsaw, searching for dark matter and extrasolar planets. Scientists have detected a strong light curve signal coming from OGLE-2014-BLG-1760. They assume that it must be caused by the presence of a gas giant planet.

One unusual feature of this event is that the source star is quite blue. This is marginally consistent with source star in the galactic bulge, but it could possibly indicate a young source star in the far side of the disk,” said, researchers.

“Assuming a upsurge source, we perform a Bayesian analysis assuming a standard galactic model, and this indicates that the planetary system resides in or near the galactic upsurge,”. According to researchers, the lens system distance equals 22,000 light years, which suggests that the system is very likely to be in the Milky Way’s bulge.

Note:

*If a star moves in front of another star, the light from the distant star is bent by the gravitational pull of the nearer star and the more distant star is magnified. Researchers used the gravitational microlensing technique, which does not rely on the light from the host stars. Thus, it can detect planets, even when the host stars cannot be detected*
