论文部分内容阅读
人类的一个最伟大之处就是:我们永远不满足于自己所知所在的世界,对未来、对地球以外的世界充满了好奇。从远古以来,各地的人民就不断地探寻了解天那边的世界。到了1990年,这一探寻有了突破性的进展,哈勃空间望远镜升空了!它最大的优势,就是可以身处太空,不受大气层干扰地拍摄照片,为人类服务。它大大地拓展了人类的宇宙视野。一些在这之前无从想象的画面被记录了,一些前人不断研究的试验被证实了,一些隐蔽性的天文险境被发现了……哈勃望远镜不仅是天文爱好者崇拜的偶像,更是我们人类向外太空进军途中的好朋友。今天让我们藉此机会重新认识一下这个闻名已久的“天文伙伴”。
Host: Imagine that we could really have a time machine that would show us what happened in the early universe, a machine that would become more powerful and give us progressively clearer pictures even as it aged. Imagine that the machine could detect worlds beyond our solar system, help map invisible 1)dark matter, and characterize the expansion of the universe.
It may come as a surprise, but this time machine does exist and is silently floating above us. Familiar enough to many to be taken for granted, the 2)NASA-ESA Hubble Space Telescope celebrates two astonishing decades in orbit on the 24th of April.
Woman: Traveling through time and space with our host, Dr. J., aka Dr. Joe Liske.
Dr. J.: (talks to himself) Wow! This thing travels over 28,000 kilometres per hour…
930,000 observations…
570,000 images of 30,000 3)celestial objects…
Twenty years. Two decades and 110,000 trips around our planet…
Woman: Dr. J., thirty seconds to show time.
Dr. J.: Okay.
After two decades of service to the scientific community and the public worldwide, tonight we are recognizing the achievements, of what is arguably the most renowned and beloved space 4)observatory in history. Welcome to the show.
Now maybe you know it for its awe-inspiring images, or maybe you know it for its fundamental scientific discoveries, but chances are you do know it. Tonight we honour the Hubble Space Telescope with a cosmic lifetime achievement award.
Host: It is not just about pretty pictures, even though Hubble is famous for some of the most 5)intriguing and, coincidentally, artistic images in the universe. Astronomers, professional and amateur alike, have been translating the magnificent colours and poetic swirls of these images into hard-edge science.
Dr. J.: It is a real honour to be able to celebrate my dear friend, Hubble. Tonight we pay tribute to your
6)venerable achievements and we look forward to the work that lies ahead of you. We will look at some of your most outstanding accomplishments and your most loved images from the past twenty years.
Host: Scientists and space enthusiasts worldwide were wowed by the deepest pictures of our universe captured by Hubble. The first Hubble deep field was taken in 1995 and opened a whole new field of research. Hubble has since repeated the success, and the latest Hubble ultra-deep field image lets us see back in time 13 billion years, just 600 million to 800 million years after 7)The Big Bang. This was one of the first and most spectacular data sets taken with Hubble’s brand new wide-field Camera Three. By studying galaxies at different epochs, astronomers can see how galaxies change over time.
Dr. J.: In November 2001, Hubble made the first direct detection of the atmosphere of a planet orbiting another star. In this case it was the sun-like star HD-209458, located about 150 light years away in the constellation of
8)Pegasus. Knowing the make-up of a planet’s atmosphere allows scientists to determine whether life as we know it could conceivably exist on the alien world.
Host: By measuring bright stars that vary predictably, known as 9)cepheids, Hubble has been able to use these stars as distance markers laying a firm foundation for subsequent measurements that led to the discovery of the accelerating universe and a more precise determination of its age.
Dr. J.: Astronomers have used Hubble to observe cepheids and to pin down their distances much more accurately. These results were used as a stepping-stone to measure the distances to 10)supernovae, which in turn told us about the scale of the universe. As a result, today we know the age of the universe with much more precision than before Hubble. It is about 13.7 billion years.
Host: When we look up at the night sky it is easy to believe that space is just a giant void with some twinkling stars and a few recognizable planets. However, we must remember that there are structures and matter that we cannot see. Hubble is helping to define, in three dimensions, the distribution of ghostly and invisible dark matter in the universe.
Dr. J.: Thanks for the past twenty years, Hubble, and here’s to many more.
This is Dr. J. signing off for the Hubble-cast, and wishing Hubble and all those who admire it a happy 20th anniversary.
主持:试想,我们真能拥有时光机,让我们了解宇宙前期所发生的一切;试想,真能有那么一台仪器,尽管年月累积,功能却愈加强大,给我们拍出愈加清晰的照片。试想,这仪器能探测我们太阳系以外的无远弗届,助我们勘测肉眼看不见的暗物质,描画宇宙膨胀的轨迹。
你也许没料到,这么一台时光机确实存在,而且正在我们头上安静地漂浮着,很多人其实早已熟知其名字,却根本不以为然。今年4月24日是美国太空总署及欧洲太空总署联和开发的哈勃空间望远镜升空二十周年的纪念日。
女人:与你一同遨游时空的有我们的主持人,J博士——乔·里斯克博士。
J博士:(自言自语)哇!这好家伙每小时飞行28000公里……
共执行930000次观测任务……
拍摄过30000个天体共570000张影像……
二十年,整整二十年,环绕地球110000圈……
女人:J博士,准备好,还有30秒钟就要上场了。
J博士:好的。
在服务科学界及全球大众二十年后的今天,我们一起来向这闻名遐迩、最受大众喜爱的太空望远镜致敬。欢迎收看我们的节目。
你对哈勃的认识,也许是源于其拍下那一张张让人油然生畏的影像,又或者是源于那些具奠基意义的科学发现,反正,你肯定听说过它。今晚,我们要给哈勃太空望远镜颁发一项“环宇终身成就大奖”。
主持:尽管哈勃望远镜因拍过一些最为奇诡又恰恰极具艺术气质的宇宙影像而著称,但这不代表它只是拍些漂亮照片那么简单。天文学家,专业的也好,业余的也好,都一直努力破解演绎这些影像显示的华丽色彩和诗意漩晕,将其转化为清晰明确的科学认知。
J博士:能为我亲爱的朋友“哈勃”庆生的确是一份荣幸。今晚,我们向你所获得的种种崇高成就致敬,并期待将来你能作出更多的贡献。我们将在节目里回顾过去二十年里你的部分卓越成果,并展示你拍下的一些最为人钟爱的影像。
主持:全球的科学家及太空迷们都曾为哈勃望远镜捕捉到的宇宙深空图片所震撼。首张哈勃深空照片是在1995年拍摄的,由此开拓了一片研究新领域。此后,哈勃一再突破,硕果连连,最新的“哈勃超深空”影像让我们回溯到130亿年前,看到宇宙大爆炸后六到八亿年的宇宙。这是哈勃望远镜以其崭新“第三代广域照相机”取得的首批最为厉害的数据之一。通过研究不同时期的星系,天文学家可以了解到各星系的历时变化。
J博士:2001年11月,哈勃首次直接探测环绕另一恒星的一颗行星的大气层。涉及到的是类似太阳的恒星HD-209458,位于150光年以外的飞马星座里。对这一行星大气层的了解能让科学家们探究我们所知的生命形态是否有可能在外星球上存在。
主持:通过监测规律光变的亮星(人称“造父变星”),哈勃成功把这些变星作为距离标示点,在这基础上继而测量计算,最终有助于加深对宇宙加速膨胀的了解,并更精确地判断宇宙的年龄。
J博士:天文学家已应用哈勃望远镜来观测“造父变星”并以此更准确地计算出它们的距离。这些数据被视作测量新星距离的进阶石,进而助我们探究宇宙的规模。所以,现在我们对宇宙年龄的猜算要比哈勃望远镜诞生前准确多了。大概是137亿年。
主持:仰望夜空,我们往往以为太空只是个巨大的空洞,有那么些闪闪恒星和些许能辨的行星点缀其中。然而,我们要知道,这里面还存在着很多我们看不见的结构和物质。哈勃望远镜正是以三维立体技术帮我们探测分辨那些神秘隐蔽的暗物质在宇宙的分布。
J博士:哈勃望远镜,感谢你过去二十年立下的功劳,祝你再接再厉,更创佳绩。
这里是J博士为你主持的“哈勃在线”( 哈勃望远镜升空20年专题纪念节目),节目结束前,再次祝哈勃及所有哈勃迷二十周年快乐。
