The discovery provides crucial evidence of the existence of impact ejecta from nearby craters in the sampling areas of the lunar probe.

这一发现为月球探测器取样区域附近陨石坑中存喷提供了关键证据。

First, the luminosity of kilonovas is expected to be orders of magnitude fainter than AT2022cmc due to the low ejecta masses expected.

首先，由于预期抛射质质量较低，千新星的亮度预计会比AT2022cmc暗上几个数量级。

The enormous amount of ash and ejecta pumped into the atmosphere from the crash would shroud the continent of impact in total darkness for some time.

因为而喷射到大气中的大量火山灰喷射，会长时间将被的大笼罩一片黑暗之中。

2 minutes and 45 seconds after DART's impact, LICIACube flew past Dimorphos to photograph the  impact site with its evolving plumes and ejecta.

美国国家航空航天局的双小行星重定向测试任务后2分45秒，利西亚立方卫星飞越迪莫福斯， 拍摄了地点及其不断扩散的羽状抛射。

And the ejecta or the stuff ejected has momentum just like rocket fuel, just like standing on a skateboard and playing catch with a bowling ball...the way you do.

所有的喷，火箭燃料一样，都有动量。就像你站滑板上把保龄球扔去一样。

The discovery provides important evidence of the presence of impact ejecta near the craters in the sampling area of Chang'e-5, which was previously determined through the analysis of remote sensing data.

这一发现为嫦娥五号取样区陨石坑附近存喷提供了重要证据，这是以前通过遥感数据分析确定的。

Because of all the ash and ejecta that was pumped into the atmosphere from the crash, the earth would enter into a deep years-long nuclear winter where temperatures around the world would be freezing without any other seasons.

由于所有的火山灰喷射因为被泵入大气层，地球将进入漫长的含核冬季，世界各地的温度将达到冰点，没有任何其他季节。

However, these collisions would also  leave the red giant in a distended and dynamically agitated state, which could  appear as G objects for a much longer timescale than the observable  lifetime of the unbound ejecta.

然而， 这些碰也会使红巨星处于膨胀且动力学上不稳定的状态，这种状态可能作为G天体存的时间远超过未结合喷的可观测寿命。
