查询词典 star dust

Even though the nebular material was ejected from the star many thousands of years ago, the close-in dust could be generated by collisions in a reservoir of objects analogous to our own solar system's Kuiper Belt or cometary Oort cloud.

虽然星云的物质在几千年前被抛射出去，星球附近的尘埃可能是附近的尘埃盘的碰撞所导致，有点类似於太阳系统的科伊伯带或是奥特云。

Regardless of size, all stars are thought to emerge in the same basic way: Gravity contracts a giant, diaphanous cloud of gas and dust and eventually ignites a star's nuclear furnace.

不管大小，所有的恒星都被认为是以同样的方式诞生的：引力使得由气体和尘埃构成的半透明状巨大云团发生收缩，最终点燃了恒星的核熔炉。

In fact, the bright star near the center of this nebula is likely only a few hundred thousand years old, powering the nebular glow as it clears out a cavity in the molecular cloud's star forming dust and gas.

事实上，这个星云中心附近的亮星大约只有几十万的年龄，它点亮星云使之看起来有个恒星形成和尘埃的空腔。

The cloud of interstellar dust looming above the Galactic plane is a large region of star formation around the star known as Rho Ophiuchi.

云的星际尘埃笼罩以上的银河系平面，是一个大区域的恒星形成围绕恒星称为rho ophiuchi 。

In fact, the bright star near the center of this nebula is likely only a few hundred thousand years old, powering the nebular glow as it clears out a cavity in the molecular cloud\'s star forming dust and gas.

实际上，该星云中央附近的明亮恒星的年龄可能仅仅几十万岁，它们引起星云发光并在分子云的恒星形成的尘埃和气体中清扫出一片空洞。

They are, however, known to develop out of the leftover, typically disk-shaped mass of gas and dust that swirls around a newborn star, so whatever direction that material is moving, which is the direction of the star's rotation, becomes the direction of the planet's orbit.

不过，据认为它们是有残留物产生，通常残留物是在新生恒星周围旋转的碟型气体和尘埃团，所以，那种物质做什么运动--即恒星的自转方向--都会成为卫星轨道环绕运动方向。

These events include two kinds of stellar explosions:(1) nova explosions, in which one of the two members of a binary star system hurls dust and gas into space;(2) much more violent supernova explosions, in which a star collapses, then throws off most of its matter.

这些事件包括两种类型的恒星爆发：（1）新星爆发，双星系统中的一员将气体和尘埃猛烈抛入太空；（2）更为猛烈的超新星爆发，那是一颗恒星崩溃时几乎把它所有物质都抛出去了。

The observation confirmed a decade of speculation that a warp in the young star's dust disk may actually be a second disk inclined to the star.

这项观测确定了10年来的推测学说，即年轻恒星的尘埃盘可能实际上时第二个尘埃盘向恒星一侧倾斜。

The telescope showed that a previously detected planet around the nearby star Epsilon Eridani is orbiting at a 30-degree angle to our line of sight, the same inclination as the star's dust disk.

哈勃望远镜显示一颗曾经被我们观测到的轨道与我们的视线成30度角，位于Epsilon Eridani附近的行星，与恒星的尘埃盘有相同的倾角。

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.

行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
