人类,从根本上说诞生于恒星 ,此刻居住在一颗名为地球的行星之上,已经开始了漫长的归家之旅。 Human beings, born ultimately of the stars and now for a while inhabiting a world called Earth, have begun their long voyage home. 这就把它置于恒星 的“雪线”上,那里的温度低到足以让水结冰。 This places it in the star 's“snow line”, where it is cold enough for water to freeze to solid ice. 一个团队发现了两颗行星,分别位于 距该恒星 的120亿公里和210亿公里的地方。 A team led by Teague found two planets located 12 billion and 21 billion kilometres from the star . 然后,他将不得不求助于恒星 目录,而这意味着测量恒星的确切位置。 Then he would have to resort to a star catalogue, and this meant measuring up the exact position of the star in question. 这颗行星也位于恒星 的可居住区,距其主星仅470万英里(750万公里)。 The planet is also in the star 's habitable zone, just 4.7 million miles(7.5 million kilometers) from its host star. .
融合是存在于恒星 中的反应,包括太阳,并且在地球上使用仍然不切实际,因为聚变反应堆尚不可用。 Fusion is the reaction that exists in stars , including the sun, and remains impractical for use on Earth, as fusion reactors are not yet available. 脉冲星毛刺的大小和频率取决于恒星 中超流体的数量和超流体涡流的流动性。 The magnitude and frequency of the pulsar glitches depend on the amount of superfluid in the star and the mobility of the superfluid vortices within.现在,添加一个冰淇淋圆锥,其尖端位于恒星 的中心,延伸到球体表面。 Now, add an ice cream cone with its point in the center of the star , extending to the surface of the sphere. 无论如何,有件事值得一提:就像之前提到的,一颗恒星的核聚变反应率取决于恒星 的质量。 And either way, here's something to ponder: As I mentioned above, the rate at which fusion occurs depends on the mass of the star . They also found that the X-ray brightness mainly depends on the size of the star . 多亏了开普勒和科研团队,我们现在知道可能有多于恒星 的行星。 Thanks to Kepler and the research community, we now know there could be more planets than stars .”. The kind of scales cosmologists deal with are much greater than the distances between stars . 多亏了开普勒和科研团队,我们现在知道可能有多于恒星 的行星。 Thanks to Kepler and the exploration community, we now see there could be more planets than stars .'. 平衡温度只考虑了恒星释放的热量,并基于恒星 与任何一颗行星之间的距离。 Equilibrium temperature only takes into account the heat radiating from the star and is based on the distance between the star and any given planet. 星际介质,指天文学中,星系中存在于恒星 之间的物质与能量. Interstellar medium, in astronomy, the matter and energy content that exists between the stars within a galaxy. When it does, it will be the first spacecraft to explore between the stars . 这个很棒的工具叫天文地震仪可以用来探测来自于恒星 的大气层的声波. It is an amazing tool called astroseismology where we can detect sound waves in the atmospheres of stars . 根据由欧洲空间局发射的依巴谷卫星所测量的数据计算,该联星系统距太阳系约11.46光年(3.51秒差距),因此其亦属于 邻近恒星 。 As determined by the European Space Agency Hipparcos astrometry satellite, this system lies at a distance of just 11.46 light-years(3.51 parsecs), and is therefore one of Earth's nearest stellar neighbours. Three of those six are within their star 's habitable zone. It provides detailed star charts showing the trajectory of the satellites against the background of the stars as seen during a pass.
