星云状的星系

The light of our galaxy is emitted from, at least, 200 billion stars converged at the existing star formation and from a great volume of stars and star clouds. It is a tremendous galaxy of whirlpool type with the confluence of a variety of interstellar materials, whose diameter is more than 7,000 light-years.

银河系是由我们所在的星系中至少2000亿颗星体和星云中的许多星体和星云所发出的光，以及各类星际物质等汇合而成的直径超过7000光年的巨型旋涡状星系。

Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of Canes Venatici. M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies.

但如果有人的眼睛足够好就可以向Canes Venatici星群眺望看见它。M51是一种Sc形态的螺旋状星云并且是整个星系中的领导成员之一。

Location of the planetary nebulae in the outskirts of the giant galaxy Messier 87 and in the intergalactic space around the centre of the Virgo Cluster of galaxies.

图中标出了位于巨椭圆星系M87外晕远处的和位于室女座星系团中心的星系间空间中的行星状星云。

The team used FLAMES, the super-efficient spectrograph at ESO's Very Large Telescope at the Paranal Observatory in Chile, to make ultra-precise measurements of a host of planetary nebulae in the outskirts of Messier 87 and in the intergalactic space within the Virgo Cluster of galaxies, to which Messier 87 belongs.

研究团队使用FLAMES——VLT阵列中的超高效摄谱仪，极为精确的测量了M87外缘和室女座星系团星系间空间中的行星状星云。

Moreover, planetary nebulae are representative of the stellar population in general.

进一步，星系中的行星状星云数量比例是相对确定的。

To date, all known galaxies and nebulae are unexceptionally flat spirals, pressed and condensed into their forms by dimensional forces.

从目前发现的星系、星云等呈现的UFO"扁平螺旋状"来看：星系、星云膨胀也是受到了外界：全方位、反方向旋凝的压力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
