supernovas

A stellar flash like this has never been seen before -- supernovas and novas expel matter out into space.

像类似的恒星闪亮以前从来没有发生过—超新星和新星向空间喷射出物质。

It takes lots of power to set the projection to on its orbit around the supernovas, burning up a sun just to say goodbye.

需要很大的动力使这影像围绕这颗超新星投影出来，燃烧一颗恒星，来跟你说再见。

The most massive of these young stars have already sped through their evolution in a few million years and exploded as supernovas.

这些年轻恒星中的质量最大者已经在不到百万年的时间里加速演变，发展成为了超新星。

Her eyes shine softly with a silvery light but can also burst in a blinding flash like supernovas.

她的眼睛闪耀着柔和的银色光芒，但是也能瞬间放射出新星一般的强光。

The most massive of these young stars race through their evolution in a few million years and explode as supernovas .

质量最大的年轻恒星会在几百万年的时间里飞快地演化完毕，并以超新星的形式爆发。

To do this, scientists used special tricks to determine the distances of many exploded stars, called supernovas, throughout the universe.

为进行研究，科学家用了一种特殊技巧来确定许多爆炸星体——超新星，在宇宙间的距离。

Supernovas can be very bright for a short time and usually release huge amounts of energy.

超级新星在一段短时间内会非常明亮，而且常常放出巨大能量。

The energy input from the supernovas could also be driving gas out of the central region.

来自超新星的能量注入还可以将气体从中心驱出。

Dark energy causes the acceleration by pushing space itself apart, altering the distances to the supernovas as it does so.

暗能量通过推动空间本身分离而产生加速度，从而改变了超新星的距离。

Explanation: One of the brightest supernovas in recent years has just been recorded in the nearby Whirlpool galaxy (M51).

解说：近年来最明亮的超新星之一出现在了临近的旋涡星系（M51）中。

Many of these newly formed stars are very massive and race through their evolution to explode as supernovas .

许多新近形成的恒星质量都很大，并会快速演化到爆发的超新星。

Explanation: One of the nearer supernovas of recent years was discovered last month in the bright nearby galaxy M100.

说明：上个月，在明亮的M100星系内发现了近年来较邻近的超新星之一。

Most supernovas spotted at the Palomar Observatory are around 1 billion light-years away, far too distant to be seen by amateurs.

大多数在帕洛玛天文台观测到的超新星都是十亿光年之外，非专业人士是很难从这么远的距离观测超新星的。

Recent images by the Chandra X-ray Observatory have shown that X-ray light surrounding the ring is likely emission from recent supernovas .

最近由钱德拉望远镜拍摄到的影像显示，围绕在光环外的X射线光好像是由最近的超新星放射出的。

Pulsars and supernovas seem to take over at about 9: 00 and are truly spectacular.

脉冲星和超新星似乎在大约900的位置上，而且确实相当壮观。

Hubble's observations of supernovas helped reveal that the mysterious energy is a constant presence in the universe.

哈勃望远镜关于超新星的资料帮助研究者揭示出，这种神秘力量在宇宙中是持续存在的。

Supernovas are a class of violently exploding stars that become super bright after eruption.

超新星是一类剧烈爆炸的恒星，爆发之后它变得极为明亮。

Chandra's improved sensitivity is making possible more detailed studies of black holes, supernovas, and dark matter.

钱德拉高敏度性能，使得我们想了解黑洞、超新星、暗物质更多细节成为可能。

Historically, only seven supernovas were known to have been recorded before the 17th century.

历史上，在17世纪之前只有7个超新星爆炸事件被记录下来了。

A collection of Hubble Space Telescope images shows distant supernovas, the death explosions of massive stars.

这是一组哈勃望远镜拍摄下来的，遥远的超新星以及这些巨大的星体发生死亡爆炸的景象。
