New Extrasolar Planetary System May Be Much Like Our Own
July 18, 2008 / Posted by: Daniella Scalice
Researchers from the NAI’s University of Arizona Team have published a new study in the current issue of Astrophysical Journal Letters of the potential habitability of the extrasolar planetary system OGLE-2006-BLG-109L. The first multiple-planet system ever to be discovered by gravitational microlensing, it has two large planets similar to Jupiter and Saturn. It’s possible that the system harbors other planets, including Earth-like planets, that are beyond the sensitivity of the microlensing observations.
Their study examines the prospects for an Earth-like habitable planet in this system. They found that two smaller putative Earth-mass planets, perhaps yet undetected, could produce a planetary architecture of a potentially habitable system. With two “terrestrial” planets and two Jovian planets, it could bear very close resemblance to our own solar system.

Sounds good to me. Now lets get some spectral analysis going on to see what those planets are made of!
