Open Studies;Pluto

No blogging for a while. Sorry, eager readers. Had other things to think about, part of the ongoing "DACE Memorial" story. Not much science adult education from now, with the honourable exception of the mature student Access programme.

So to shift the mood let me just mention how amazing I find the images from Pluto: a more geologically active world than expected. Why? My guess is something to do with the tidal interaction between Pluto and Charon. And why on earth (or "on Pluto") does it have huge mountains? Great stories to come, I'm sure.

Reminds me a wee bit of the many "first images from..." stories from the Voyager spacecraft, how many surprises there were, particularly among the moons of the outer planets. Every time we go somewhere new there are surprises - new questions to answer! The Pluto images are all over the media. You don't need to see them again here. Instead let me share this image of Saturn's moon Hyperion, taken by the NASA Cassini mission in 2005, surely one of the weirdest looking bodies of the solar system. A tiny world, roughly 300 km across, its spongy appearance is still unexplained.
