Gravitational Lensing: A planet of 6 times the mass of Jupiter

Italy - Researchers from the National Institute of Nuclear Physics (INFN) have identified a new planet outside our galaxy about 6 times the mass of Jupiter, using a method of observation based on the phenomenon of "gravitational lensing" .

Scientists have used a new method of observation from space: the effect of gravitational microlentille. This occurs when a distant star (source) is aligned with an object closest (lens) that reflect light from the source and allow the observer to identify exoplanets that emit little light. The exoplanet is visible if its presence causes a distortion of the light emitted by stellar objects aligned.

As the phenomenon depends on the mass of the object lens and movements of the object and the star, the gravitational lensing effects are possible. In addition, alignment of the star and the object with the observer on Earth is exceptionally rare. Thus astronomers can not observe the exoplanet only once, when sufficient conditions are met. It is sometimes difficult to confirm a hypothesis of observation.

Dr De Paolis, one of the researchers, is excited to be able to detect planets at distances if phenomenal. He says: "What is interesting about this technology is that it allows to distinguish planets the size of Jupiter and even less in other galaxies." "That's something unique" he says.
