| Shoot, a fella could have a pretty good weekend in Vegas with all that stuff! |

| ▲ | HPsquared 2 hours ago | parent | next [-] | | Come to think of it, quite a lot of sugary treats have space-themed names. Milky Way, Mars, Starburst, Orbit gum... I'm sure there are others. | | |
| ▲ | KineticLensman an hour ago | parent [-] | | "Galaxy" (in the UK) is the obvious one. Incidentally, Mars bars were named after the Mars family who owned the company that made them, not the planet. | | |

| Aren't we starting to figure out that life (self-organization) is the most likely outcome for planets with our conditions? Maybe "our conditions" are also too strong of a requirement Check out Blaise Arcas on MLST and Nick Land on Dwarkesh. Self organization might just be the second law of thermodynamics in action |

| I know one theory proposes comets seeded earth with essential materials. But what seeded comets?? It’s just chance with extra steps, no? |
| |
| ▲ | malfist 2 hours ago | parent | next [-] | | The big bang did. And following it, supernovae. But there's a lot we don't know and science is always advancing! For example, JWST observed early galaxies are both larger and more diverse materials than we expected. Means there's something new to learn! | |
| ▲ | anechouapechou an hour ago | parent | prev | next [-] | | There's a theory that at the very beginnings of the universe, as it cooled down, there was a period where the average temperature of the universe was between 0-100º C, meaning the whole universe was within a "habitable" temperature range, and this could have supercharged the creation of the building blocks of life. I think I learned about it on a Veritasium video... Maybe someone knows which one? :) | | |
| ▲ | Retric an hour ago | parent | next [-] | | Veritasium videos are often extremely misleading. In this case the cooling universe lacked carbon for these organic compounds. Life cares about 0-100c because of water which depends on Oxygen would be missing etc. Just as example in one video he refers to the field outside of the wire carrying the energy for electricity, however EM waves propagate at the speed of light and fall off at the square of distance. Electricity can travel thousands of miles without that kind of falloff but doesn’t propagate as fast because it’s electron density in the wires that causes what we think of as electricity. He then setups up an antenna and … well you get the idea. | |
| ▲ | tsimionescu 16 minutes ago | parent | prev [-] | | A "habitable" temperature range, without water and carbon, would be entirely meaningless. |

| ▲ | gaoshan an hour ago | parent | prev | next [-] | | When Carl Sagan said, "The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself" he was poetically accurate. The comets are seeded with the remains of untold countless exploded stars. | |
| ▲ | antonvs 20 minutes ago | parent | prev | next [-] | | It's sorting and mixing. Comets, asteroids, and planets all had different factors governing their formation (sorting). When comets or asteroids hit planets, you get a mixture of those different compositions. | |

| So they found some sticky unidentified alien slime on an asteroid... This sounds like something straight out of an alien movie. |

| As I’ve been reading findings of extraterrestrial organic molecules recently, I wonder: do we know there was no contamination? I’m going to be sad if it turns out someone sneezed into it and was afraid to tell their manager. |
| |
| ▲ | gus_massa 29 minutes ago | parent | next [-] | | Most organic molecules are different from it's mirrored version, and living thing usually produce only one version. But inorganic reactions produce an even mix of 50% and 50%. So in most cases it's easy to spot. Also, some sugars or amino acids are very common here and others very rare, and the commet probably has another mix. Also, the ammount of isotopes of the atoms (like Carbon 14) is probably different. | |
| ▲ | Normal_gaussian 3 hours ago | parent | prev | next [-] | | There are papers covering contamination prevention and detection for every stage of the mission. There are papers with the designs and intentions before launch and papers with how well it went and their specific findings after return. Here is one sick paper covering some of the clean rooms https://ntrs.nasa.gov/citations/20230005897 | |
| ▲ | reactordev 5 hours ago | parent | prev | next [-] | | >”Once soft and flexible, but since hardened, this ancient “space gum” consists of polymer-like materials extremely rich in nitrogen and oxygen. Such complex molecules could have provided some of the chemical precursors that helped trigger life on Earth” That would be some stale big league chew if that were the case. By orders of billions of years. Making it the oldest wad of big league chew we know of in existence. ;) | | |
| ▲ | foxyv an hour ago | parent [-] | | I'm almost certain that the gum in baseball cards originated from the big bang. | | |
| ▲ | reactordev 30 minutes ago | parent [-] | | Not the Big Bang, the Big Ban. The ban of smoking or tobacco products on TV. Up until the 1980s, it was common to see a pitcher up there with a mouth full of Kodiak or Chaw. Spitting their nasty tobacco-stained split all over the mound. |

I will then ask other non-experts in the field if the experts are minimally competent or not." | | |
| ▲ | gblargg 4 hours ago | parent | next [-] | | I was thinking the same as parent while reading this. Mentally this activates the same thinking as on those medical tests with a high false positive rate and low incidence, so that most positives are false. I'd like to see in the article how they rule this out. Ideally I'd like to hear that they have measures in place that would allow accidental lapses in isolation to fail and they'd still be able to tell that it was Earth contamination. It's a reasonable concern and having it addressed (with something more satisfying than "they're experts, duh!") makes this kind of finding all the more interesting. | | |
| ▲ | pixl97 2 hours ago | parent [-] | | I mean, it's a concern, but there are numerous other odd things in the findings that would not be caused by ground contamination such as the amount of stardust contained in these samples versus other asteroid samples, or the huge amounts of clay/water created minerals found so far. There are plenty of other articles on the isolation procedures they've taken so far to this point including putting off opening the container for months because of a stripped screw. |
