The bright waning gibbous moon rises an hour or more after nightfall tonight. If you look closely, you’ll see a star near the moon. It’s Elnath, the star representing Taurus the Bull’s northern horn. It’s a fairly bright star, though it’ll be obscured by the moonlit glare. After rising, the moon and Elnath stay out all night long tonight.

Elnath is a special star, because it pretty much aligns with the galactic anticenter. The galactic anticenter is the direction in the sky that’s about-face from the center of our Milky Way galaxy.

The moon always moves in front of the background stars, traveling its own diameter eastward every hour. By tomorrow night, the moon’s change of position will be obvious. It will have moved eastward into the constellation Gemini the Twins.

For a fixed reference to the galactic anticenter, use Elnath, Taurus the Bull’s second brightest star. The galactic anticenter lies some 3 degrees east of Elnath on the stellar sphere. By the way, the width of your thumb at an arm length away spans roughly 3 degrees of sky.

主要讲的是金牛座的二等星Elnath在今晚夜空的情况。后几天月亮将移动到双子座的附近位置。

今夜，明亮的凸月在黄昏后一小时左右升起。如果你仔细观察，将会在它的附近看到一颗星。这颗星便是象征着金牛座尖角的Elnath（五车五- -！这个星实在是翻不出来，网上查到的是这么个名字）。它是一颗非常明亮的星，尽管在月华中略显模糊。凸月升起，彻夜与Elnath相伴闪耀于夜空。

Elnath是一颗十分特殊的星，因为它几乎与galactic anticenter（直译了：反银心星）相伴行。反银心星因其与银河系中心方向彻底相反而成为了天空中的方向标。

月亮总是于星空之前，沿着自身的运行轨迹不停的向东方移动。而明晚月亮位相的变化将更加明显，它将向东方移动进入双子座星域。

今晚的亏月大概在入夜后一个小时左右升起，认真观察的话，会发现它身边有颗若隐若现的星星--五车五，今晚它们将长夜相伴。在金牛座中，五车五处于北牛角的位置。

Elnath is a special star, because it pretty much aligns with the galactic anticenter. The galactic anticenter is the direction in the sky that’s about-face from the center of our Milky Way galaxy.
五车五很特别，因为它与反银心方向几乎处于同一平面。反银心方向即天球上与银心方向相差180度的点所在的方向。

The moon always moves in front of the background stars, traveling its own diameter eastward every hour. By tomorrow night, the moon’s change of position will be obvious. It will have moved eastward into the constellation Gemini the Twins.
月球每时每分都在向东运行，到了明天晚上，月球的位置会发生明显变化：它将运行到双子座前面。

For a fixed reference to the galactic anticenter, use Elnath, Taurus the Bull’s second brightest star. The galactic anticenter lies some 3 degrees east of Elnath on the stellar sphere. By the way, the width of your thumb at an arm length away spans roughly 3 degrees of sky.
金牛座第二亮的星星五车五可以作为反银心方向的固定参考：以银心为中心，反银心方向与五车五呈3度夹角，即我们的拇指与我们的前臂形成的夹角大小。

自己也是似懂非懂的

。高手请指点一下什么是银心方向，谢谢！

将金牛座第二亮星的Elnath作为反银心星的固定参考物，丛恒星天文测度而言反银心星正处于Elnath移动3度左右。另外，当你手臂伸直时你拇指的宽度大概就是3个天文测度。

It’s a fairly bright star, though it’ll be obscured by the moonlit glare. After rising, the moon and Elnath stay out all night long tonight.

Elnath is a special star, because it pretty much aligns with the galactic anticenter. The galactic anticenter is the direction in the sky that’s about-face from the center of our Milky Way galaxy.
今晚，夜幕降临后的一个小时，皎洁明亮的盈月升起。如果你在离月亮不远处观察，你会看到有一颗星星在月亮附近。这颗星星是Elnath，代表北金牛座金牛的牛角。虽然被月光笼罩着看起来有点模糊，但这是颗相当明亮的星星。今晚Elanth上升后和月亮彻夜出现在夜空。

Elnath十分特殊，因为它几乎与银河中心相反点（ galactic anticenter）对齐。银河中心相反点（ galactic anticenter）是指天空中某个地点，与银河中心点呈相反方向。

The moon always moves in front of the background stars, traveling its own diameter eastward every hour. By tomorrow night, the moon’s change of position will be obvious. It will have moved eastward into the constellation Gemini the Twins.

For a fixed reference to the galactic anticenter, use Elnath, Taurus the Bull’s second brightest star. The galactic anticenter lies some 3 degrees east of Elnath on the stellar sphere. By the way, the width of your thumb at an arm length away spans roughly 3 degrees of sky.
星星是夜空美丽的背景，月亮常常运行到其上方，每个小时都想东方行进大约自身直径的距离。截至明晚，月亮位置的变化会变得明显，她会向西闯入到双子座中。
利用金牛座第二亮星Elnath是寻找银河中心相反点（ galactic anticenter）的固定参照点，银河中心相反点（ galactic anticenter）大约在Elanth向东3度地方。顺便补充下，3度在空中大小约莫为手臂的长度和大拇指的宽度形成的夹角。

P.S
galactic anticenter 这个中文咋说呢？

今晚夜幕降临之后的一个小时或是更长一些时间，明亮的亏凸月将会升起。如果仔细观察，你会看到月亮的附近有一颗星星。它就是位于金牛座北牛角上的Elnath, 尽管在月亮的光芒下它显的有些晦暗，但是它仍然是颗非常耀眼的星星。月亮升起后，这颗Elnath也将会在今晚彻夜停留在夜空。
Elnath is a special star, because it pretty much aligns with the galactic anticenter. The galactic anticenter is the direction in the sky that’s about-face from the center of our Milky Way galaxy.
Elnath 是颗非常特别的星星，刚好和反银心方向位于同一条线上。反银心方向刚好是背对银河中心的方向。

The moon always moves in front of the background stars, traveling its own diameter eastward every hour. By tomorrow night, the moon’s change of position will be obvious. It will have moved eastward into the constellation Gemini the Twins.
月亮总是会在群星中徘徊徜徉，每隔一个小时向东运行一个月亮的位置。明天晚上月亮变换的位置会变得明显。它将会向东移动到双子座的位置。
For a fixed reference to the galactic anticenter, use Elnath, Taurus the Bull’s second brightest star. The galactic anticenter lies some 3 degrees east of Elnath on the stellar sphere. By the way, the width of your thumb at an arm length away spans roughly 3 degrees of sky.
利用Elnath,金牛座的第二颗最明亮的星星可以对反银心方向做个定位。在恒星系中，反银心方向处于Elnath以东3度夹角的位置。打个比方说，大拇指距离胳膊的宽度大致就是天空中的3度角。

反银心是在天球上与银河系的银心在相对位置上的一个点，它位于御夫座的范围内。从太阳系看，银河的反银心视一个很独特的点，但从银河系整体来看，这个点并没有任何意义。

在银河座标系统，银心在人马座的方向上，对应于银经0°，而反银心在 180°之处。
