Plasticbag World of Scientific Nonsense Part 273

by David on April 28, 2007

A planet has been found that’s only 1.5 times the size of earth and appears to have liquid water running on its surface… Wow. That’s pretty amazing. What interests me is twofold. Firstly, obviously, is there life. Secondly, if there isn’t, how easy would it be to introduce some?

Firstly, this planet hasn’t been direcly observed. Its presence is inferred from the behaviour of its star. No liquid at all has been discovered and certainly not observed on this planet. Certainly no water. It does not ‘appear to have water’ on its surface; running, skipping, or doing anything else.

Secondly – how easy would it be to introduce some life? Well, at 20 light years the planet is 9,460,800,000,000 km from us, or thereabouts. If Tom climbed into his car and started driving now at a pretty sharpish 120 km/h (75mph) he should arrive in about 9 million years, assuming he didn’t stop off for a burger and a snooze.
