Loads of prebiotic molecules found in Milky Way?[edit]
FWIW - (For being aware only of newly published relevant studies - not necessarily to incorporate into the main article) - On 8 July 2022, astronomers reported the discovery of massive amounts of prebiotic molecules, including for RNA, in the galactic center of the Milky Way Galaxy.[1][2] - Stay Safe and Healthy !! - Drbogdan (talk) 13:07, 10 July 2022 (UTC)

But what is pseudo-panspermia?[edit]
... and how does it differ from not any kind of panspermia?
If you don't accept full panspermia, you believe that life on earth originated from events in a soup of small organic molecules. Some of these molecules arrived from space, some were randomly synthesised here from atmospheric CO2, H2O and N2 by lightning strikes. I've no idea what the relative amount from each source would be. Maybe the two sources contain different things, and both are necessary for the origin of life? My best guess is that "pseudo-panspermia" hypothesises that life could not have originated here without the extra-planetary arrival of certain substances. Is this right? Does the hypothesis specify which substances? Maproom (talk) 22:11, 13 August 2023 (UTC)
