- A star is formed when a cloud of gas collapses from the interstellar medium toward high density. 一个气体云自星际物质中坍缩,密度达到很高时,即形成了一个恒星。
- The outer layers of the star crashed into the interstellar medium, driving a shock wave that is still visible today. 这颗星的外层撞到星际物质,由其产生的冲击波至今仍然可见。
- The shock acts as a searchlight by revealing the structure of the interstellar medium. 冲击波能揭示出星际介质的结构,扮演着探照灯的角色。
- A star is formed when a cloud of gas collapses from the interstellar medium toward high density . 一个气体云自星际物质中坍缩,密度达到很高时,即形成了一个恒星。
- Simple laws of physics suggest, that gas-dust complexes in the interstellar medium may evolve, first into protostars and subsequently into stars. 简单的物理学定律揭示出,星际介质中的气尘复合体可以进化,先是演化为原恒星,接下去再演化为恒星。
- What new information have we gleaned about the comparatively dense gas-dust complexes of the interstellar medium over the past dozen years? 过去的十几年里,有关星际介质的较密气尘复合体我们探明了哪些新东西呢?
- This time-lag depends on the distance the signal has traveled through the interstellar medium: the longer the distance the greater the time lag. 这个时间差依赖于信号在星际介质中传播的路程:路程越长,时间差越大。
- In a relatively short time (about 1000 years) the entire shells will be ejected into space, joining the gas and dust in the interstellar medium. 在相对较短的一段时间里(大约1000年)整个壳层将被抛入太空,加入到星际介质的气体和尘埃中。
- Fluorescing in ultraviolet light, the cast off material trails behind the giant star as it plows through the surrounding interstellar medium at 130 kilometers per second. 在巨星后方的抛出物质以每秒130公里的速度穿过周围的星际介质,并且这些物质在紫外光线下发出荧光。
- Moreover, the kinetic energy from supernova explosions energizes the interstellar medium, providing energy for the formation of the next generation of stars. 此外,爆炸释放的动能也直接推动星际物质的结合,为新一代星体的形成提供能量。
- Around the periphery of the disk, a shock front or wall of water forms;outside the shock front, the water moves slower than the local wave speed (analogous to the subsonic interstellar medium). 在浅盘的周围,形成激波前缘或水墙,在激波前缘之外,水的运动速度低于该处的波速(类似于次音速的星际介质)。
