Supernova Condensate is a blog about our place in the Universe. Of astronomy, chemistry and life in the big bad bubble of academia.
Invader Xan is a molecular astrophysicist and part-time alien invader, who spends life looking at very small things on very large scales, and trying to better understand the chemistry of interstellar space.

I love sci fi. Really. While countless people whine about the lack of accuracy in sci fi generally, I’ve come to realise that suspending my disbelief is usually more fun★. Anyway, if we’re honest, deconstructing science in movies is like … Continue reading
I love stars. I’ve heard galactic astronomers say in the past, how stars are boring, and once you’ve seen one star you’ve seen them all. Personally, I couldn’t possibly disagree more. I could list a hundred reasons why stars are … Continue reading
If you were to be able to travel forward in time by about 7 billion years and take a look at our parent star, what might you see? What would the Sun, by then weary with old age, look like? … Continue reading
This Universe is full of carbon. Well… Not full really. I mean, technically it’s mostly full of absolutely nothing, closely followed by dark energy and dark matter… and if we’re talking about things we can see, then it’s mostly full … Continue reading
Did you know that, seen in high energy gamma rays, the Moon is actually brighter than the Sun? Remarkably, the photons that make up this image carried over 20 million electron volts of energy each. That already sounds like a … Continue reading
