Extrasolar planets: More giants in focus

John Chambers1
Top
A fresh analysis of data from gravitational microlensing surveys for planets orbiting stars other than the Sun finds that gas-giant planets similar to Jupiter are more common than previously thought.
The Sun's planetary configuration seems ideally suited to the emergence of advanced life. Small, rocky planets lie in the pleasantly warm region close to the Sun.
