Automatic TRANSCRIPT

Right okay. What is a lot. Easier is chemical formula which is c three h two three carbon atoms. Two hundred with a name like that. You'd think out you know. Dozens of different elements in oxygen and nitrogen. Rest of it. But no c. Three h two a cyclope Panel idea i think that And it's as simple carbon-based component as they say to to to talk about a combination but the the excitement comes from the fact that it may be a precursor to more complex carbon containing compounds which is all about life as we so often end up talking about How was it found by the alma telescope. once again the atacama large millimeter submillimeter array in northern chile. Not far from san pedro de atacama Way up that. It's about five thousand meters. Top end of the of the hill on which the telescope is mounted on what what scientists were doing was essentially looking at the spectrum of titan's atmosphere in the millimeter wave region And so he's find lots and lots of features the spectral features that either. Absorption or emission lines simon in visible light spectroscopy. Where you break things up with the prison to bit more complicated for millimeter. Wave spectroscopy but scientists will looking through that looking at the whole series of spectral signatures from alma and they found this chemical fingerprint is a lovely quote from connor. Nixon who's a planetary scientist at nasa goddard. Space flight center is actually a leader of the research. And he said when. I realized i was looking at cyclo. Penali- my first thought was well. This is really expect a understatement. It's very nice and so we have you know. In the world of science we we do know of the existence of c three h two elsewhere in space most notably in clouds of gas clouds Hit light nebulous essentially index pace. And the the the interesting part about it is this stuff tends to like to react with other chemicals and so hit in in deep space where you're looking at gas clouds nabulsi and you find date you can sort of e can come to terms with that because a these places are almost vacuum that that very very low density gases if you've got cyclic propel alighting practicing. I think that might be how you pronounce it. Just perfect it and then someone will give the throne. Yeah yeah yeah. I'll have to go find some chemists friends anyway The the the thing about these rat. Sorry rarefied gas clouds in space is. The molecules are a long way apart so even though the stuff loves to react with other molecules it can't find a and that's it. That's the rationale for finding in these Distant gas clouds in our galaxy but then a planetary atmosphere is quite different from that. You know some the on the much high pressure. It's rarified these outer edges but it's much higher pressure and so the a lot more molecules in titan's atmosphere in close proximity to c three h two so the question is how does it survive. Where does it come from. And the In fact the nasa press release puts it perfectly says dense atmosphere like titans. Hives of chemical activity a. That's why this this particular observation is of interest because it makes you wonder where the three inch to is coming from..

Coming up next
