Nick Howes’ talk inspires reflections on the threat of asteroids and comets and how amateur astrophotographers can contribute to science. The News: This month we take a look at NASA’s new draft 2015 Technologies Roadmap and discuss the advances in robotics, space propulsion, power transfer and nanotechnology that NASA hope to seed. Next up is some research from NASA’s Jet Propulsion Laboratory that suggests the discolouration on Europa’s surface might be irradiated salt from the moon’s subsurface ocean. Finally, we take a look at the discovery, using ESO’s VLT, that globular clusters in the Centaurus A galaxy are far heavier than they should be – perhaps harbouring vast amounts of dark matter.
