最後,由於中子星疾速的自轉,或是伴星自身的演化,物質的流入停止, x射線輻射減弱,這顆中子星就呈現出了毫秒脈沖星的面目。As gas pools, it turns into stars, whose outflows and explosions push material back out into intergalactic space ? a process of negative feedback
當氣體集中形成恆星,所產生的噴流與爆炸會將物質向外推回星系際空間,這是一種負向的反饋機制。In perhaps the most unusual proposal of all, scientists from nasa ' s jet propulsion laboratory ( jpl ) in california are proposing to build a probe that uses heated water jets to descend to depths of up to a hundred meters through the frozen ice caps at the martian poles inn search of organic matter
在或許是最不一般的建議的倡導下,加利福尼亞州航空航天局噴氣推進實驗室( jpl )的科學家們正在計劃建造一臺探測器,使用熱水射流穿透火星極地的冰帽,深入到100米以下,搜尋有機物質。With the sun locating at the centre, our solar system is consisted of the eight planets and their satellites, dwarf planets, asteroids, comets, meteoroid and interplanetary matter
我們的太陽系,是以太陽為中心,由八大行星及其衛星矮行星小行星彗星流星體和行星際物質所構成的天體系統。Solar system ' s main member includes : sun ( star ), nine planets ( including earth ), innumerable planetoids, multitudinous satellite ( including moon ), but also has the comet, the meteor as well as the massive dust matter and the thin gaseous state matter
太陽系的主要成員有:太陽(恆星) 、九大行星(包括地球) 、無數小行星、眾多衛星(包括月亮) ,還有彗星、流星以及大量塵埃物質和稀薄的氣態物質。Since the chandra data shows that particle acceleration is still occurring in this hotspot, the jet must have struck the companion galaxy relatively recently, less than about a million years ago ( i. e. less than the light travel time to the hotspot )
錢德拉的數據顯示熱點中的物質仍在被加速,因此噴流撞擊伴星系的事件應該發生在不久前,大約不到100萬年(少於光線運行到熱點的時間) 。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。If the magnetic stripes on mars are confirmed to be caused by plate tectonics, this would be the first direct evidence of the existence on another world other than earth of such geological process. source : nasa
注一:流體靜力學平衡hydrostatic equilibrium是指星體有足夠的萬有引力去令星體的物質固為球體或接近球體,而不至於物質向內崩塌或飛散。Another school of thought is that the material is ejected smoothly from the star, and the rings are created later on due to formation of waves in the outflowing material
另一些學術思想是物質被這顆星平滑的噴射,結果這些外射的物質流由於波的作用后來形成了戒指樣的殼。One of the most popular hypothesis is the supermassive black hole theory. when materials surrounding the black hole fall into it, large amount of energy is released. galaxy collision may create the supermassive black hole at the center
最流行的理論是星系中心有一個特大質量黑洞,當星系物質流進黑洞的時候,就會產生出大量的能量,而中心內的黑洞可能便是星系碰撞時形成的。According to meteor scientists, there will be two maxima for leonids this year, and hong kong may encounter the first one at dawn on 18 november. about 20 meteors per hour are predicted. however, as the meteoroids stream is less dense than 2001, the shower is expected to be less spectacular even with the absence of the moon
據專門研究流星的學者預測,今年的獅子座流星雨極大值即高峰期有兩個,香港可於11月18日凌晨遇上第一個,每小時可見約20顆流星,但由於流星物質已遠較2001時稀疏,故即使當日並無月光干擾,相信這次獅子座流星雨亦不會太壯觀。Matter will be transferred from the red giant to the white dwarf when the gravity of the red giant at its surface is weaker than that of the white dwarf. when sufficient matter is accreted onto the surface of the white dwarf, nuclear reactions will start and sustain for a short period on the white dwarf surface. enormous energy is produced
當紅巨星的表面引力比白矮星弱時,部分物質會盤旋流進白矮星內,當足夠的物質積聚在白矮星表面,便會燃點起熱核反應,產生出巨大的能量,這種爆發會維持下去,直至所有氫氣耗盡。Observation of meteors throws light on our understanding of the motion of the celestial bodies in our solar system, physical properties of the earths upper atmosphere and the spatial distribution of meteoroids which helps choosing safe and proper trajectories for launch vehicles such as artificial satellites
觀測研究流星對研究太陽系天體的運動地球高空大氣物理性質了解流星體分佈這項資料對選擇航天器如人造衛星的運行軌跡十分重要等都有重要的意義。Another possibility is that large - scale spiral waves in the disk, similar to the spiral arms observed in galaxies, hasten the inflow of matter
另一個可能性是,類似星系旋臂的大尺度螺旋波,加劇了物質的向內流動。And most of them were bright fireballs that shined below magnitude 0. many people noticed the red head and green trail of the meteor. colour of the meteor is an important clue to understand the composition of the meteoroid
當中為數很多都是0等以下的火流星,而且還帶有顏色,不少人都看到流星紅頭綠尾的有趣現象,這為我們追查流星體物質的成分留下了重要的線索。Black holes are invisible by definition, yet the gas and dust falling into a black hole are heated to high temperatures and glow furiously. if there is a companion star orbiting around a black hole, astronomers can investigate the central black hole by examining the accreting matters from the nearby companion star
顧名思義,黑洞漆黑一片,目不可見,但其實那些墮入黑洞的氣體和塵埃,會因受熱而發出熾烈的光芒,因此假如黑洞有伴星的話,天文學家便可透過觀測伴星物質流入黑洞時所形成的吸積盤,對中心的吞噬者進行研究。Thursday, the leading edge of an 80 - kilometer long slick of benzene reached harbin ' s municipal water inlets
星期四,長達80公里的被化學物質苯污染的水流開始進入哈爾濱市供水系統的取水河段。Shanghai linkstar logistics co., ltd. is a class a forwarder invested by hk julink investment group
