Flame Nebula
Can someone look at Talk:Flame Nebula, please? The objection raised there sounds valid, and sources are given. The German article already states, point blank, that the nebula and Alnitak are in no way related because the nebula is about twice as remote from Earth as the star. However, a new publication cited in Alnitak claims that the real distance of the star is much greater, which might or might not eliminate this objection. I'm really out of my depth here, so I need help. --Florian Blaschke (talk) 12:32, 27 January 2018 (UTC)

Earth analog
I've encountered a small issue here too. An editor shortened the list found in the section "Size" in this edit, but the text still refers to Ganymede and other bodies that were removed from the list. I'd appreciate if someone could look at the edit and decide if either the shortening of the list was problematic and undo it, or, if it is fine, adapt the text. I'm don't have relevant expertise so I can't tell which is the better solution. --Florian Blaschke (talk) 12:39, 27 January 2018 (UTC)


 * If none of our erudite RefDesk editors leap to your aid on this, you might try a note at Wikipedia talk:WikiProject Astronomy which seems to be quite active. Alansplodge (talk) 12:58, 27 January 2018 (UTC)

Is there a basis for that woman a week after giving birth has negative hormonal changes?
I saw today a woman that behaved very not nice, she justified her behavior by saying that woman after birth has hormonal changes that make her nervous (negative changes). I feel that it is a stigma. I believe that there is hormonal changes (for example prolactin increasing and progesterone decreasing. Are there more?) but the issue is that I'm not sure that these changes make negative behavior rather than positive behavior? 2A02:ED0:53CB:C100:D919:7C9A:B876:948A (talk) 18:23, 27 January 2018 (UTC)
 * You mean beyond Post-partum depression? Abductive  (reasoning) 20:24, 27 January 2018 (UTC)
 * No. I'm asking generally about every woman. 2A02:ED0:53CB:C100:4121:1E69:4E2A:7C15 (talk) 23:10, 27 January 2018 (UTC)
 * You meant, "yes", beyond post partum depression. Abductive  (reasoning) 23:31, 27 January 2018 (UTC)
 * Exactly. I didn't notice the word "beyond". Sorry about that. 2A02:ED0:53CB:C100:4121:1E69:4E2A:7C15 (talk) 23:47, 27 January 2018 (UTC)
