An asteroid was discovered last week by astronomers using the University of Hawaii’s Pan-STARRS 1 telescope. It’s moving at a tremendous clip – and is on its way out of our solar system after whipping through on a trajectory that took it inside the orbit of Mercury. The Minor Planets Centre at Cambridge, Massachussets, has … More Did we just rendezvous with Rama?
Eyes across the US will be pointing skywards today as the total solar eclipse sweeps across America – the first visible from the continguous continental US since 1979. There’s been a buzz about fake ‘eclipse glasses’ on the market, which doesn’t surprise me. Humanity has a very dark side and, of late, it hasn’t been … More The solar eclipse – and what it means
It’s two years this week since my Mum passed away. She was hugely interested in the why of the universe and usually asked me if she wanted something about it explained. It’s a while since I’ve done a science post, so I thought I’d run one this week. It’s about why our law of energy … More When energy isn’t conserved – a physics conundrum
It was the winter solstice in New Zealand this week, and from now on we’ll be getting longer days and lighter mornings. Except, for a couple of weeks, we won’t. It’ll get darker, later, for a while. So what gives? I mean, the solstice is meant to be the moment when it all turns around… … More Why mornings get darker after the winter solstice

Earth’s going to be whacked in 1984, 1987, 1999, 2012, 2018, apparently, with all the effect of a nine-iron on a golf ball, and NASA are hiding the truth … More Earth’s comet apocalypse at the hands of Gliese 710
For your amusement, here’s a post I wrote in 2012 (enter TARDIS sound…) +++++++++++++++++++++++++++++++++++ I don’t know why the seventh planet out from the Sun is the butt of so many jokes. Well, I do. and it’s lame, lame, lame. So today I’m going to get to the bottom of it, as it were. More … More Why the name of the seventh planet is funny – redux
It occurred to me the other day that the first broadcasts of The Brady Bunch – which originally aired on US TV in 1969 – have reached the following stars, all 47-48 light years distant: Nu Lupi, Theta Boötis, Asellus Primus, Iota Ursae Majoris, Talita (HR7898), Psi Capricorni, 111 Tauri, Psi Serpentis, Psi Capricorni and … More A list of star systems reached by ‘The Brady Bunch’ broadcasts
