  1. Systems as diverse as the early universe, the interstellar medium, red giant stars, and supernova explosions are currently the focus of intense studies utilizing sophisticated computer models - models which require large quantities of nuclear data as input

    如早期的宇宙，星際介質，紅巨星，超新星爆， x -射線爆和-射線爆等多樣的系統，這些核天體過程是利用復雜的計算機模型，進行重點研究的焦點。
  2. What new information have we gleaned about the comparatively dense gas-dust complexes of the interstellar medium over the past dozen years ?

    過去的十幾年裡，有關星際介質的較密氣塵復合體我們探明了哪些新東西呢？
  3. Stars are born from a kind of primal soup known as the interstellar medium.

    恆星是由一種稱為星際介質的「原湯」形成的。
  4. Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis

    課程的主題包含了：行星、行星形成；恆星、太陽、正常的恆星、恆星形成；恆星演化、超新星、緻密天體（白矮星、中子星及黑洞） 、波霎、雙x -射線源；星團、球狀及疏散星團；星際介質、氣體、塵埃、磁場、宇宙射線；距離階梯；星系、正常及活躍星系、噴流；重力透鏡；大尺度結構；牛頓宇宙學、宇宙的動力膨脹及溫度發展歷史；宇宙背景微波輻射；大霹靂核合成。
  5. Simple laws of physics suggest, that gas-dust complexes in the interstellar medium may evolve, first into protostars and subsequently into stars.

    簡單的物理學定律揭示出，星際介質中的氣塵復合體可以進化，先是演化為原恆星，接下去再演化為恆星。
  6. 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

    在相對較短的一段時間里（大約1000年）整個殼層將被拋入太空，加入到星際介質的氣體和塵埃中。
  7. As gas flies away from the detonated star, it decays and reacts with the interstellar medium, producing light in many different colors and energy bands

    當氣體從爆炸的中心遠離時，它的亮度會減弱，並和附近的星際介質發生交互作用，產生各種顏色和波段的光。
  8. Introduction to astronomy provides a quantitative introduction to physics of the solar system, stars, interstellar medium, the galaxy, and universe, as determined from a variety of astronomical observations and models

    天文學導論這門課提供了對太陽系、恆星、星際介質、星系及宇宙等的物理入門。這些都建立在各種的天文觀測及模型的基礎下。
  9. A star is formed when a cloud of gas collapses from the interstellar medium toward high density.

    一個氣體雲自星際物質中坍縮，密度達到很高時，即形成了一個恆星。
  10. The outer layers of the star crashed into the interstellar medium, driving a shock wave that is still visible today

    這顆星的外層撞到星際物質，由其產生的沖擊波至今仍然可見。
  11. It says that the stars indeed rotate at different speed, but the density of the interstellar medium form a wave. at the wave front, where the density is higher, star formation is enhanced. that is why we find young stars along the spiral arms and old stars elsewhere

    這個理論認為雖然恆星會以不同速度移動，但星際物質的密度會產生波動，在密度最高的波陣面會催生出新的恆星，這解釋了為何通常在旋臂會找到新生恆星，而在其他地方只有古老恆星的原因。
