What happens when you wake up naked in outer space…

One of the genius moments in Kubrick’s 2001: A Space Odyssey comes when Dave Bowman, locked out of the Discovery in a ‘pod’, without his suit helmet, re-enters anyway, via the emergency airlock. He’s unprotected in vacuum – but he doesn’t die instantly, or freeze, or explode the way people usually do in movies when… More What happens when you wake up naked in outer space…

Planet 9 won’t be as big as Uranus. Really.

This week’s news in the Astronomical Journal that Mike Brown and Konstantin Batygin of CalTech have predicted a ninth planet got the usual barrage of silly media headlines about ‘discovery’. The thing is, Brown and Batygin haven’t found anything. They’ve hypothesised that there’s a planet. And they are not the first to wonder about some… More Planet 9 won’t be as big as Uranus. Really.

Here’s why. The problem is that near-Earth size, insolation and orbit – which is all we know just now – doesn’t necessarily mean Earth-like. The planet was… More Why the new ‘Earth 2.0’ is more likely to be Venus 1.1

More a sort of taunt, really, for those of us stuck… More It’s winter in New Zealand. I blame Earth’s axial tilt.

Why the Pluto flyby means we need to re-think our view of the solar system

Yesterday’s Pluto flyby’s been one of the most amazing unmanned space moments of the last half century – up there with the Voyager probes and with the Mars rovers. It’s also only the beginning. Over the next sixteen months the probe will transmit the data it picked up during that super-fast cruise through the Pluto system.… More Why the Pluto flyby means we need to re-think our view of the solar system
