Review: Strange New Worlds by Ray Jayawardhana.

It’s weird to stop and think that we now live in a time that we know of the existence 573 new exoplanets, and by the time this cyber-ink goes to press, that rolling number will become obsolete. “In my day,” (my halcyon youth of the 70’s) Eight-tracks where still cool and astronomers guessed that exoplanets had to be common, but no one had as of yet found definitive evidence that this was indeed the case.

Now, calculations have shown that Kepler may be sensitive enough during the span of its four year mission to detect another first; exo-moons, or Earth-mass moons orbiting Saturn-mass planets. Kepler is in an Earth trailing orbit and sports a 0.95 meter 95 mega pixel (that’s an array of 42 2200×1024 pixel each CCDs!) aperture camera that will stare at the star-rich Cygnus-Lyra region looking for tiny dips in the apparent brightness of over a 100,000 stars. Expect the tally of new exo-planets to climb in the coming months!
