I know that this has almost nothing whatsoever to do with libraries, books, or anything else I generally deal with, but boy, it's the coolest news story I've seen all week:
New 'Super-Earth' Found in Space
It's orbiting a red dwarf star (Gliese 581) just about 20 light-years from us, it's about half again the size of Earth, and there's a great chance it has liquid oceans.
Jackpot.
When I was 12, there were nine planets. Nine (including Pluto). One big star (the sun) that we paid attention to, and a whole scads of more distant points of light that we knew barely anything about other than magnitude, size and which constallation to look towards to see them. That was pretty much it. We know a lot more now, including the locations of over 220 planets outside our solar system. And some of them defy all previously imagined laws of planetary formation. Gas giants should not be able to form closer to a G class star than Mercury is to the sun. But at least one seems to have done just that. Go figure.
And 22 years later I see that we've got a curiously Earth-like (potentially Earth-like) rock circling a very small, dim star right in the neighborhood. Granted, this thing is in our neighborhood in galactic terms only. A Solar sail might get you there by the year 3000. A big enough ship--maybe a hollowed out asteroid powered by a nuclear engine--might be able to spend a year accelerating to a speed approaching light-speed (186,232 mi/sec the last time I checked), coast most of the way then spend another year decelerating to make orbit on final approach. Total trip time might be 25 years. The Constitution-class U.S.S. Enterprise could get you there in about a month at Warp 6, but that's even less likely than the first two possibilities. A wormhole-powered gateway of some type could get you there in a few minutes.
Anyway, read the article and take a minute or so to wonder what cosmic knowledge your kids will be reading about in another 22 years.
