其中銀河系的化學演化在其中更是具有極其重要的地位,對銀河系化學演化的認識是理解整個銀河系演化的基礎,並對恆星演化與核合成理論提供約束。In this area, visitors can select videodisc programmes on stellar evolution and star systems. they can also visualize the spatial relationship between component stars of such famous celestial configurations as the orion and the big dipper
觀眾可選看關于恆星演化和恆星系統的影碟節目,他們亦可看到著名的獵戶座和北斗七星內各星體之間的空間關系。This hourglass nebula is the closing phase of a sun - like star s life as its outer layers are ejected
沙漏星雲是與太陽相似的恆星演化最後階段,恆星把外殼噴出,形成行星狀星雲。Within these tight knots of stars, observers in recent years have discovered bodies that are forbidden by the principles of ordinary stellar evolution ? but that are naturally explained as smashed - up stars
在這些緊密的恆星集團內,觀測者近年已發現通常的恆星演化理論所不容許存在的恆星,於是很自然將它們解釋成撞擊而形成的恆星。An understanding of the stellar energy sources is still more vital for the problem of stellar evolution.
弄清恆星的能源對恆星演化的研究是更為關鍵的問題。Frequent space museum visitors should know that neutron star is one of the possible final products of stellar evolution
