H three plus

After my last post, I was asked by my friend Alice (from over at the zooniverse*) about what kind of tenuous chemical bonds might form in interstellar space, and why they might be destroyed at higher pressures. I agreed to … Continue reading

Something from Nothing

Now, when most people think about space, they imagine it to be a total vacuum. Completely empty of anything whatsoever. The thing is, that’s not quite true. Those spaces between the stars aren’t quite as empty as you might think. … Continue reading

The quiet voice of interstellar glycine

So I’ve been sitting in on an online NASA astrobiology conference, The Organic Continuum from the ISM to the Early Solar System. Unfortunately I’ve missed most of it already, having only heard it was happening this evening when I was … Continue reading

Might as well be water on the Sun

Water is all the rage. It gets mentioned in every single high profile space mission of late. Searching for water on Mars, water inside Europa, water in the atmospheres of exoplanets. Going to the Moon? Don’t forget to check for … Continue reading

Rubbing the right elbows

Well it’s not often you get told about a symposium that’s 100% relevant to your research interests! I’m posting this almost entirely to remind myself to look into it. Seriously, I’d love to go along. Even if it means grovelling … Continue reading

Life in the smoggy freezer?

The twin questions of how and where life could begin from prebiotic chemistry are pretty big ones. Indeed, despite the now famous Miller-Urey experiment creating amino acids by zapping simple chemicals with lightning bolts, we’re not much closer to a … Continue reading

How different could life be under a red dwarf sun?

I’ve been mulling over this paper for a few days now. Last week, NASA JPL put out a press release about cool stars having a different mix of life forming chemicals to sun-like stars. The release was immediately picked up … Continue reading
