    在上周少有的觀測中，卡西尼的照相機顯示出土星的一個新環和其他一些壯觀景象，包括從土衛二伸展出的數萬千米細指狀冰物質以及回望地球的一張照片。
  2. As the nuclear burning moves outward to the fresh material in a shell surrounding the core, the star bloats into a so - called red giant

    當核燃燒向外進行到核心周邊殼層的新物質時，恆星會膨脹成所謂的紅巨星。
  3. This at least accounts for the fact that a particular group of meteoroids shares with its parent comet more or less the same orbit, which can remain relatively unchanged over eons. an immediate consequence is that our earth makes periodic rendezvous with this meteoroid swarm, thereby culminating in a regular display of these celestial fireworks. to name a few, we have the lyrids in april and the geminids in december

    流星雨的成因是地球遇上了一群密集的流星體，一般相信，流星群是由周期性彗星分解出來的物質或由瓦解了的彗核所形成，所以流星群和其母體彗星有大致相同的軌道，由於流星群的軌道頗為固定，所以地球會周期性地穿越這些流星群，形成固定出現的流星雨，例如四月天琴座流星雨十二月雙子座流星雨等。
  4. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born

    在這一過程中，這些恆星撕扯著在其誕生處周圍剩餘的星雲物質。
  5. Just as mercury has a much shorter year than earth ? a mere 88 days ? the material in the inner parts of a disk invariably takes less time to complete one orbit than does material in the outer parts

    正如同水星繞日周期（只有88天）較地球短，在圓盤內側的物質繞行軌道一圈所需的時間，永遠比外側的物質短。
  6. Specks form into clumps, these collide with other clumps, and the process continues until all the matter in any given orbit is concentrated into one object ? a planet

    微粒形成團塊，團塊之間相互碰撞，周而復始直到給定軌道上的所有物質集中成一個物體? ?行星。
  7. Dem l71 presents a textbook example of the double - shock structure expected to develop when a star explodes and ejects matter at high speeds into the surrounding interstellar gas

    Dem l71是雙激波結構的標準範例，人們認為其產生於恆星爆發並以高速向周圍星際氣體拋射物質的時候。
  8. Such a process can take place in the low mass x - ray binary systems where the mass transfer from the companion to the neutron star can be larger than 0. 5 solar masses. if the neutron star in the low mass x - ray binary accretes the matter, the central densities can reach to a state that strange - matter seeds are formed in the interiors of the star

    在這個系統內，中子星可能會吞噬超過0 . 5個太陽質量的伴星物質，當中子星吸收了這些物質后，中心的密度會增加至足以產生奇異物質種子，這些種子會開始吞噬四周的中子物質，釋放出大量中微子和反中微子，令星體冷卻。
  9. Combined with the observational properties, we have constructed a theoretical model of a contact binary with a total mass of 1. 8 mo. our initial model is a detached binary in which the primary is very close to its roche lobe

    並且由周期變化時標得到磁滯效應可能是引起wuma型相接雙星的角動量損失的主要物理機制。結合wuma型相接雙星的觀測特性，我們建立了一個總質量為1 . 8m 。
  10. Saturn ' s rings may look smooth and even when viewed through a telescope but they are in fact made up of clumps of particles and may be much denser than realized, scientists said on tuesday

    土星環也許看起來很平滑，甚至從天文望遠鏡里看去也是一樣；但土星環事實上是由許多粒子組成的塊狀物質所構成，而且比想像中的還要密集，科學家周二表示。
  11. Candidates for stellar - mass black holes were identified mainly by the presence of accretion disks of the right size and speed, without the irregular flare - ups that are expected from disks around other compact objects

    鑒別恆星質量黑洞主要靠合適大小和速度的增大圓盤的存在，沒有認為從其它緊密物體周圍閃耀的無規律的閃光。
