Editor's note: The last three weeks I have been dealing with family emergencies, and I apologize for the break in this blog.
Astronomers have discovered 18 new Jupiter-sized planets orbiting stars slightly larger and slightly older than the Sun, bringing the number of confirmed exoplanets to over 700. They aren't "hot" Jupiters. either. They orbit their stars at distances roughly comparable to the distance at which Jupiter orbits the Sun.
So, some of these systems might give us an inkling of the future of our Solar System.
