星云

Though Bob Fera just calls this a test image, I think he has done a nice job with the North American and Pelican Nebulas.

尽管Bob Fera只把这个成为一张&测试片&，我想他已经把北美星云和塘鹅星云拍得非常好了。

Pictured above is the west end of the Veil Nebula known technically as NGC 6960 but less formally as the Witch 's Broom Nebula.

上面的影像是面纱星云的西端，也被称为NGC6960，通俗的称谓是巫婆的扫帚星云。

But this well-studied example of a planetary nebula, produced near the end of the life of a sun-like star, is now understood to have a surprisingly complex geometry.

但事实并非如此。螺旋星云事实上已经是已被广泛研究的行星状星云的很好的例子。它是类太阳恒星在寿终时所演变成的。

This image from the Hubble Space Telescope reveals theCat's Eye Nebula to be one of the most complex planetary nebulae known.

这张来自哈伯太空望远镜的影像，透露出猫眼星云是现知结构最复杂的行星状星云之一。

Place your cursor on this stunning view through dark skies over western Australia to highlight wonders of the southern Milky Way -- including the famous Southern Cross, the dark Coal Sack Nebula, and bright reddish emission regions surrounding massive star Eta Carinae.

zL(~，UU1S/eR0 将鼠标移到这幅壮丽的西澳洲星空影像上，就可以看见南天银河的珍宝，包括著名的南十字、黝黑的煤袋星云、和大质量海山二星周围明亮的发射星云。

The bright bluish nebula below and left of center is NGC 1999, a dusty cloud reflecting light from an embedded variable star.

影像中左下方的蓝色明亮星云编号是NGC 1999，它是一个内部藏着变光星的反射星云。

A planetary nebula is an expanding cloud of gas ejected from a star that is nearing the end of its life.

行星状星云一个由来自中心濒临死亡恒星所释放出的气体组成的正在膨胀的星云。

The spoke features seem to indicate that the Helix Nebula is itself an old and evolved planetary nebula.

这种辐条结构，似乎表明螺旋星云本身是一个老切高度演化的行星状星云。

The white dot at the Helix's center is this Planetary Nebula 's hot , central star .

螺旋星云中央的白点就是这个行星状星云炽热的中央星。

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）。
