Buy me a coffee?
Writing this blog is a labour of love, and one which I evidently need a little encouragement towards on occasion. If you like what I write, the best way to show your gratitude would be to fuel my caffeine addiction and buy me a coffee to say thank you. All coffee donations are gratefully accepted!

Black holes singing in space
One of the things which particularly caught my eye in this week’s Carnival of Space was that article from the quite marvellous Science in a Can about a singing black hole! This black hole is about 250 million light years away … Continue reading
Carnival of Space 262
Ladies and gentlemen and variations thereupon, I bid you welcome to this week’s edition of Carnival of Space. With Curiosity’s daredevil landing on Mars this week, there’s a distinctly martian flavour about this carnival! Whether this is your first time … Continue reading

Black hole nucleosynthesis
If I had to pick a handful of favourite things in all of physics, black holes and nuclear fusion would be among them. Hands down. This interesting little paper which I stumbled across earlier (via a link to the APS … Continue reading

An iris of stars
Around 50 million light years away, lies a rather lovely spiral galaxy known as NGC 1097. Seen in infrared light by Spitzer in this image, it reminds me a little of an egyptian Eye of Horus. That pupil however, is … Continue reading
Supermassive!
Just the concept of black holes is captivating, isn’t it? No wonder they’re central to the plotlines of so many movies and sci-fi stories. The idea of an object so dense that light can’t travel fast enough to escape from … Continue reading
Space Ghost?
Ghost hunting isn’t typically the sort of thing you’d expect the Chandra space telescope to be doing. Evidently though, it’s rather good at it! Specifically an x-ray ghost betraying the presence of a galaxy’s supermassive black hole. Feel free to … Continue reading
You are now leaving the Milky Way
