      Wait, so stars are constantly producing complex organic structures?

      No Effin Way!

      Everything works out in the end, sometimes even badly.

      I call bullshit. Unless these are really really really cold stars.

      Fucking awesome.

      That means, if true, we could narrow down the search for life even further.

      Looking only for planets which have a certain-aged star near them.
      As well as, in the nearer future, making estimates as to how many planets could have life on them!

      WOO!

      How would that work? As far as I'm aware, the first organic molecules on Earth are still thought to have largely arisen in the test tube that was Earth's early atmosphere. We know by experiment that the atmosphere was able to do this. If you discount planets which didn't have the right star nearby at the time of formation (and how you're supposed to do that I have no idea), you probably discount the only example of life we know.

      It's not surprising. I remember reading that the center of our galaxy tastes like raspberries due to all organic molecules floating around.

      Ummmm.... what?
      We don't have a star nearby?

      Also, just because they can arise from Earth, doesn't mean that's the only way.

      Exactly, thanks for discrediting your nonsensical post.

      I don't get it.
      Do you think the Sun is not a star?

      This study is about stars in their planetary nebula phase of evolution being found to create organic molecules, this is after the star becomes a red giant. Our sun is nowhere near this phase and the study finds no evidence for organic molecules being ejected by stars like our sun.

      Oh, I either missed that part or forgot by the time I replied.
      Well I suppose then you'd have to figure out how far the molecules have been ejected from planetary nebulae and then find the Earth like planets in that trajectory.

      The organic molecules in the nebula could contribute to an interstellar cloud which forms another solar system with earth-like planets. This is how it's thought our solar system was formed. From looking at that article, it doesn't seem like the organic molecules are actually ejected but created in the already ejected circumstellar environment. This is interesting but it doesn't imply anything too new. Interstellar clouds, which are made from the ejections of stars, have been known to be made of organic molecules, just a little earlier than we thought this study suggests.
