与天文学有关的国外名人简介英文50词案例一
Spitzer (Spitzer Space Telescope) Spitzer (1914-1997) first proposed the idea of launching a space telescope in 1946. He believed that the space telescope was superior to the ground telescope in two aspects. Firstly, the space telescope will not be affected by atmospheric turbulence, and the resolving power of the telescope will only depend on the aperture; Second, the space telescope can expand the observation band, such as observing infrared and ultraviolet rays absorbed by the atmosphere.

Chandraseka (Chandraseka X-ray Observatory) (Chandraseka is the winner of the Nobel Prize in Physics in 1985. Source: Wikipedia) One Chandraseka limit is enough to make Mr. Chandraseka (1910-1995) famous in the history of astronomy. He calculated that white dwarfs have a mass limit (about 1 .4 times the mass of the sun), and if the mass of the remaining debris at the end of star evolution exceeds this limit, it will continue to collapse into neutron stars and even black holes.
案例三
Hubble (Hubble Space Telescope) (source of Hubble in 1931: Wikipedia) Hubble (1898-1953) is known as the father of galaxy astronomy. At that time, two academic leaders, shapley and Curtis, were arguing about the size of Yumu. Hubble's work marked the big debate. He confirmed the existence of extragalactic galaxies and established Hubble's law, which brought strong evidence to the theory of cosmic expansion.

Pachas (Iba Valley Satellite) Pachas (about 190- 120 BC) was an ancient Greek astronomer. Many milestone achievements are attributed to his name. Such as the discovery of the equatorial precession, the establishment of trigonometry Q and spherics (known as the father of azimuth astronomy), the compilation of a catalog (one of the oldest catalogs in the world-), and the creation of the concept of magnitude, which classifies stars according to their brightness.
案例五
Galileo (Galileo probe) Galileo (1564-1642) made great achievements in astronomy. He used telescopes for astronomical observation, and successively discovered sunspots, mountains
and craters on the moon, the profit and loss of Venus, the four major moons of Jupiter, and so on. This series of discoveries dealt a heavy blow to the then popular Aristotle system and ptolemaic system.。
