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.

Out in the deep dark recesses of interstellar space lie vast sprawling clouds of molecular gas and dust. You can actually think of them a little bit like rainclouds. As they get denser, they scatter more light. Eventually light becomes … Continue reading
Earth orbit is not a good place to drop your tools. And I have to say, I feel rather sorry for astronaut Heidemarie Stefanyshyn-Piper, who did exactly that during an EVA during the STS-126 service mission to the space station. … Continue reading
Evidently, Venus has once again managed to flummox experts across the planet with its latest stunt — the appearance of a bright spot amongst the clouds in its southern hemisphere. An awful lot of people are talking about it, but … Continue reading
