天文学家发现一个碟状的尘埃围绕着一个巨型星体,该星体正在它的成长阶段,说明星体无论大小,形成的机制是一样的。
Astronomers have found a disk of dust around a huge, massive star in its early stages of growth, indicating that stars big and small form by the same mechanism.
但是它的规模大约是我们的太阳的20倍,而且环绕着一个碟状尘埃,尘埃的材料与成长中的小星体周围的碟状尘埃相似。
But it has a mass about 20 times that of our sun and is surrounded by a disk of material similar to what is found around smaller, growing stars.
它们‘清楚地显示了至少一些巨型恒星由环绕的碟状气体和尘埃凝聚而成,就如我们的太阳在45亿年前一样。’
They "clearly show that at least some massive stars grow by accreting material from a circumstellar disk of gas and dust, just like our sun did roughly 4.5 billion years ago."
现有理论指出:行星是恒星诞生之后的残留物——碟状尘埃和气体的产物。
Current theory holds that planets are made from disks of gas and dust left over after star birth.
接下来,天文学家们检测了近期发生星系碰撞的微妙标志,例如扭曲的碟状中心或者拖着尾巴的恒星。
Next, the astronomers checked the galaxies for the subtle signs of a recent galactic collision, such as a warped disk or a trailing tail of stars.
孩子吞食的是一枚“纽扣”电池,一枚银色扁平碟状样的东西,是用来给遥控器,玩具,音乐贺卡,浴室秤及其它家用电器等供电的一枚电池。
The child had ingested a "button" battery, one of those flat silver discs used to power remote controls, toys, musical greeting CARDS, bathroom scales and other home electronics.
