威尔逊山天文台系列的每一件都配备了最先进的CCD相机,探测器阵列,光谱仪和光谱仪。所有这些仪器都有助于天文学家记录观测结果,创建图像,并剖析从宇宙中远处物体流出的光。此外,为了帮助校正大气条件,60英寸望远镜配备了自适应光学系统,可以获得更清晰的图像。在最大的望远镜建成后不久,天文学家开始涌向使用它们。特别是,天文学家埃德温·哈勃(Edwin P. Hubble)利用胡克(Hooker)来观察那些(当时)被称为“螺旋星云”的物体。正是在威尔逊山,他在仙女座“星云”中对造父变星进行了着名的观察,并得出结论,这个物体实际上是一个遥远而独特的星系。仙女座星系中的这一发现震撼了天文学的基础。几年后,哈勃和他的助手米尔顿·胡马森进行了进一步的观察,证明宇宙正在扩张。这些观察结果构成了现代宇宙学研究的基础:宇宙的起源和演化。它对不断扩大的宇宙的看法使宇宙学不断寻求对大爆炸等事件的理解。

澳大利亚西澳大学天文Essay代写:螺旋星云

Each of the Mount Wilson Observatory series is equipped with state-of-the-art CCD cameras, detector arrays, spectrometers and spectrometers. All of these instruments help astronomers record observations, create images, and dissect light that flows from distant objects in the universe. In addition, to help correct atmospheric conditions, the 60-inch telescope is equipped with an adaptive optics system for sharper images. Soon after the largest telescope was built, astronomers began to use them. In particular, astronomer Edwin P. Hubble used Hooker to observe objects that were called “spiral nebulae” at the time. It was in Mount Wilson that he made a famous observation of the Cepheid variable in the Andromeda Nebula and concluded that the object was actually a distant and unique galaxy. This discovery in the Andromeda galaxy shocked the foundations of astronomy. A few years later, Hubble and his assistant Milton Humason conducted further observations to prove that the universe is expanding. These observations form the basis of modern cosmological research: the origin and evolution of the universe. Its perception of the ever-expanding universe has led cosmology to constantly seek an understanding of events such as the Big Bang.
