I was asked the other week, on Facebook, why Jupiter doesn’t just fly off into space. You know, it’s so enormous, surely the Sun can’t hold it. Actually, it can. Jupiter is around 300 times the mass of Earth, sure – but it’s only 0.09 percent the mass of the Sun. Not only can the Sun… More The Sun’s big. Really big. And really grippy.
The other day I threw a crumpled bag into a bin and almost missed. It hung on the edge for a while. Quite suddenly it began collapsing into the bin, flexing as it did so. In a strict sense this was all understandable; I’d crushed the bag, meaning the energy of my fingers was stored… More Do humans see patterns where there aren’t any? Let’s talk…
I never fail to boggle at the convenience of social media. Even as the southern hemisphere is swathed in a wet and dark winter, a friend of mine on tour in north Sweden has been extoling the experience of the midnight sun on Facebook. More a sort of taunt, really, for those of us stuck… More It’s winter in New Zealand. I blame Earth’s axial tilt.
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
Back in the early twentieth century the Solar System was a simple place. Four small planets (three of them possibly inhabited) huddled close to the Sun, girdled by an asteroid belt widely supposed to be an exploded planet. Beyond lay four gas giants with their own moons (also likely inhabited). In and around them orbited various comets.… More How Pluto got (wrongly) demoted to ‘dwarf’ planet
The world’s in Pluto frenzy this month. NASA’s SOFIA observatory aircraft has been operating out of Christchurch, New Zealand, to capture data on Pluto’s atmosphere via star transit spectrometry – and on 14 July, some 3662 days after leaving Earth, the New Horizons probe will storm past Pluto and its family of moons. It’s our first visit… More Pluto frenzy is upon us this month
I’ve always had an interest in discovering the secrets of the universe – you know, does dark matter exist, why we can’t have antigravity – and why every weird steak from crocodile to ocelot always has to taste of chicken. This last has been puzzling me a lot. Not least because even chicken doesn’t taste… More Why does everything taste of chicken, except chicken?
