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’m tired of seeing this trite show up in every corner of the internet I frequent. Can we please just get rid of it? Please? No. Nonononononononono. You can say whatever you like, but don’t be using science to justify … Continue reading
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
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
In astronomy, the typical way to give the mass of a large object is in solar masses, denoted M⊙. This isn’t an exact measure, but it’s good to a suitable degree of accuracy. For example, Sirius A is about 2.02 M⊙. … Continue reading
