原句的结构其实是 there is no sky..., no sunset ...., and an indefinable longing and regret（最后一部分只是把 in passing leaves 调到了an indefinable longing and regret 前面而已）
所以就是 There is A, B and C 这样的结构。
顺便再给楼主解释一下形容词语序和逗号/and 摆放的问题（ 摘译自
，有能力尽量读原文哦）
形容词语序 royal order of adjectives：
形容词分类
Determiner—articles (a, an, the), possessives (your, his, her, my, their, our), number (ten, several, some), demonstratives (this, that, those, these)
Observation or Opinion—cold, ugly, tasty, heroic, retired, carefree, enthusiastic, soft, opinionated, priceless
Size—huge, minuscule, petite
Shape—square, oblong, circular
Age—ancient, old, young
Color—green, gray, yellow
Origin—British, Albanian, Hawaiian
Material—wooden, velvet, plastic, aluminum
Qualifier—typically a noun used as an adjective to identify the type of the noun—hound dog, evening gown, bumper crop—or an adjective ending in -ing that describes a noun’s purpose—adding machine, walking stick, marching orders
以上分类，越在上的离名词越远。（size 和 shape 有人归为一类）
形容词之间的逗号
①相同类别的形容词之间要加逗号或 and
②不相同类别的形容词间不加逗号
③三个或三个以上同类别形容词连续出现时，最后一个形容词之前可以 and 与 逗号同时出现，否则其他情况两个不能同时用于一个形容词之前
以下五句都是对的
The scary and hungry bears charged the tent.
The threatening, scary bears charged the tent.
The scary, threatening, and hungry bears charged the tent.
The scary, threatening, hungry bears charged the tent.
The scary and threatening and hungry bears charged the tent.
这一句不对：The scary hungry bears charged the tent. 因为scary 与 hungry 是一类词，之间要加逗号或者 and
以下几句都是对的
a long blue velvet drape （三个形容词来自不同类别，不加逗号或 and）
the gnarled and hideous plastic tubing （可以用逗号代替 and）
a loose-fitting blue and green Hawaiian shirt （只有 blue 与 green 来自同一类别，故他们之间加 and）
some hard, tasteless, and stinky yellow candies （同上）
some hard, tasteless yellow candies （hard 与 tasteless 同类，加逗号）
