爱德温·哈勃 Edwin Hubble
Content Introduction
中文
爱德温·哈勃(Edwin Hubble,1889年11月20日-1953年9月28日)是一位具有里程碑式意义的美国天文学家,他革命性地改变了我们对宇宙的认知。在20世纪初期,人们普遍认为宇宙只包含银河系,而哈勃通过对遥远星云(现称为河外星系)的光谱观测,证明了这些星云实际上是独立于银河系之外的星系,极大地扩展了我们对宇宙空间的理解。
哈勃最伟大的贡献是发现了星系的退行速度与其距离成正比的关系,即著名的哈勃定律。这一发现直接导致了宇宙膨胀理论的提出,成为现代宇宙学的基础。哈勃定律不仅揭示了宇宙的动态本质,而且为估算宇宙年龄和宇宙尺度提供了关键依据。
除了这些突破性发现,哈勃还积极推动了天文学技术的进步,对星系形态学进行了深入研究,并建立了星系分类系统,为后来的天文学研究奠定了基础。他的工作对美国乃至世界天文学发展都产生了深远的影响,使他成为20世纪最伟大的天文学家之一。在当时美国蓬勃发展的科技和经济背景下,哈勃的科研工作得到了大力支持,这与美国的科研环境和文化氛围密不可分。

Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was a landmark American astronomer who revolutionized our understanding of the universe. In the early 20th century, it was widely believed that the universe contained only the Milky Way galaxy. Hubble, through spectroscopic observations of distant nebulae (now known as extragalactic galaxies), proved that these nebulae were actually galaxies independent of the Milky Way, greatly expanding our understanding of the vastness of space.
Hubble's greatest contribution was the discovery of the relationship between the recession velocity of galaxies and their distance, the famous Hubble's Law. This discovery directly led to the proposal of the theory of the expanding universe and became the foundation of modern cosmology. Hubble's Law not only revealed the dynamic nature of the universe but also provided key evidence for estimating the age and scale of the universe.
In addition to these groundbreaking discoveries, Hubble actively promoted the advancement of astronomical technology, conducted in-depth research on galaxy morphology, and established a galaxy classification system, laying the foundation for future astronomical research. His work had a profound impact on the development of astronomy in the United States and the world, making him one of the greatest astronomers of the 20th century. Against the backdrop of the booming science and technology and economy in the United States at that time, Hubble's scientific research was strongly supported, which is inseparable from the scientific research environment and cultural atmosphere of the United States.

A: 你听说过爱德温·哈勃吗?
B: 听说过,好像是个天文学家?
A: 是的,他证明了宇宙在膨胀,对现代宇宙学做出了巨大贡献。你知道他的一些主要成就吗?
B: 我只知道他发现了河外星系,这改变了我们对宇宙的认知。
A: 没错!他还提出了哈勃定律,描述了星系退行速度和距离之间的关系。
B: 哈勃定律?听起来很专业。能简单解释一下吗?
A: 简单来说,就是距离我们越远的星系,退行速度越快。这表明宇宙正在不断膨胀。
