India a major player in Earth observation satellites - Out of Space

Duncan Steel Oct 15, 2019

While many imagine that countries like the USA and Europe dominate space activities, in fact India is now a major player on this stage.

Night lights of NZ from orbit - Out of Space

Duncan Steel Oct 10, 2019

Climate change – determination over despair - Ariadne

Robert Hickson Sep 19, 2019

  There is much to be despondent about looking ahead to the consequences of a changing climate. But adopting Jonathan Franzen’s defeatism isn’t the best response. Reducing adverse impacts of climate change isn’t as simple as regulating automotive emissions, banning a pesticide of refrigerant, or changing to LED lights. But nor is it as … Read More

Duncan Steel Sep 19, 2019

The discovery of a true interstellar comet – a comet passing through the solar system having arrived, presumably, after having been thrown out of some other planetary system orbiting another star – re-opens a long-debated question in science: is life unique to Earth, or is it common in the galaxy? The panspermia hypothesis holds that life is common in the … Read More
