replies: text: There are definitely good reasons for merging the two articles.  However, I think there are subtle differences between then that may not necessarily warrant a merger.  Although the two terms are often used interchangeably, cosmochemistry generally refers to the analysis of physical samples (meteorites, etc.) whereas astrochemistry often refers to the spectroscopic analysis of astronomical phenomenon for which no physical samples are available.  Cosmochemistry is a well-developed discipline and its article could definitely be expanded on its own.  Just my two cents. :)  — Preceding unsigned comment added by Topher385 (talk • contribs) 03:56, 23 July 2011 (UTC)

message: : do people using the term astrochemistry really deal strongly with "chemistry" in the astronomical sense, meaning nuclear reactions in stars? It would be good for someone to find an online reference, which shouldn't be hard. 
i replace "nuclear chemistry" by "nuclear physics" because the wikipedia is not intended to confuse people. Astronomers normally say "chemistry" when we talk about nuclear reactions. That's just a historical fact. So when astronomers also talk about reactions between chemical elements, you need to be careful to distinguish the real physical nature of what we're talking about.

replies: text: Nope, nuclear synthesis is a part of astrophysics. Chemistry, by necessity, deals with molecules, so chemists find the interiors of stars (where there are no molecules) rather uninteresting. Modest Genius talk 00:03, 2 February 2007 (UTC)

message: Lithium is not a product of stellar nucleosynthesis. All Lithium was created during big bang nucleosynthesis. Lithium is fused very quickly to heavier elements in stars and therefore destroyed, so the universes total Lithium content goes down as time goes on.  —Preceding unsigned comment added by 76.178.149.67 (talk) 23:00, 19 September 2007 (UTC)

text: BTW: Lithium sources are Big Bang and radiative spallation of carbon and such in interstellar space. In stars lithium generally go down. Rursus dixit. (mbork3!) 19:14, 18 July 2011 (UTC)

message: This article currently looks more like an essay than an actual article. It could do with some editing, splitting it into sections and making it easier to read. As I don't have time to do this myself right now, I've marked it as requiring cleanup.

message: The name astrochemistry is misleading because it is not about chemistry in stars. A better name might be celestial chemistry in analogy to celestial mechanics. Bo Jacoby (talk) 14:44, 20 March 2013 (UTC)
replies: text: Astrochemistry is the term used by those in the field (astrochemists), and many book titles and conference titles include this word. Wikipedia should reflect the common convention for names, not try to invent a more logical name that no one will recognise. Jolindbe (talk) 16:21, 5 August 2013 (UTC)
thread_title:  misleading name 

message: I think the article could use a good once over, with several major additions and edits. Starting with the lead lection, I propose the following: 
Astrochemistry is the science devoted to the study of chemical processes at work in astrophysical environments, including the interstellar medium, stellar and planetary regions.  Astrochemistry is a kind of overlap between its two parent disciplines, Astronomy and Chemistry. Astronomy is concerned with detecting molecules in the interstellar medium and stellar environments by research of the sky, where chemistry is interested in processes that transform molecular species. Molecular spectroscopy is responsible for making these discoveries. Aspects of current research include trying to understand the processes likely to lead to the formation of these molecules, as a function of the properties of their environment. Particular interest is focused on the formation, composition, evolution and fate of molecular gas clouds, because it is from these clouds that solar systems form.' 
I am very interested in constructive feedback and suggestions. EzPz (talk) 17:56, 23 June 2013 (UTC)

message: The "Research" section contains the following text:
:Astrochemistry overlaps with astrophysics and nuclear physics in characterizing the nuclear reactions which occur in stars, the consequences for stellar evolution, as well as stellar 'generations'. Indeed, the nuclear reactions in stars produce every naturally occurring chemical element. As the stellar 'generations' advance, the mass of the newly formed elements increases. A first-generation star uses elemental hydrogen (H) as a fuel source and produces helium (He). Hydrogen is the most abundant element, and it is the basic building block for all other elements as its nucleus has only one proton. Gravitational pull toward the center of a star creates massive amounts of heat and pressure, which cause nuclear fusion. Through this process of merging nuclear mass, heavier elements are formed. Carbon, oxygen and silicon are examples of elements that form in stellar fusion. After many stellar generations, very heavy elements are formed (e.g. iron and lead).
Massive stars are capable of fusing everything up to iron in a single generation (see Stellar nucleosynthesis and Stellar evolution), and the supernovae at the end of their lives are capable of producing numerous elements beyond that (see Supernova nucleosynthesis), so the statement that it takes "many generations" to form iron and lead is not accurate (indeed, it seems to be fairly hotly debated whether any of the very first generation of stars would have been light enough not to forge the entire spectrum of elements available to stellar+supernova nucleosynthesis). Furthermore, the entire paragraph has no citations. 
I am not a regular editor, but this is a fairly glaring error and has been present in the article for nearly a decade and a half, so I thought I'd flag it for review. 2600:1700:AA70:CCF:0:0:0:122 (talk) 01:03, 17 March 2020 (UTC)
