This image from the Astronomy Picture of the Day is an artist's illustration of what BLG-109 - a planetary system recently discovered using the technique of gravitational microlensing - might look like:
Recently a detailed analysis of microlensing system OGLE-2006-BLG-109 has related brightness variations to two planets that are similar to Jupiter and Saturn of our own Solar System. This discovery carries the tantalizing implication that interior planets, possibly including Earth-like planets, might also be common.
