A Procession of Blue Dots
Take a long, hard look at this little animation. It may not look like much at first. A small collection of blue spots, swirling around a mass of light. But what you’re looking at is a system of alien planets orbiting … Continue reading

Twinkle Twinkle Stormy Star
The weather here on our little blue world has, of late, been somewhat turbulent. Storms lash my hometown on the UK’s Southern coast, Australia slowly bakes under oppressive heat, North America is deep frozen by the errant polar vortex, and … Continue reading
Counting the stars…
In honour of Ada Lovelace day, I thought I should write a little about a personal hero of mine. The lady in this picture is none other than Annie Jump Cannon, responsible for one of the most important and well … Continue reading
Life under a blue sun?
So an article I wrote for Discovery last week revisited the idea of whether life could survive under a red sun, and what challenges it might face. Thing is, while red dwarfs may be exceptionally cantankerous little things, it seems … Continue reading
