Astronomy as a Journey

After Galileo sent a telescope to the sky for the first time in 1609, the possibilities of astronomical observations increased very strongly. This year was the beginning of a new era in science - the era of telescopic astronomy. Galileo's telescope on present concepts was imperfect, however to contemporaries it seemed to be a miracle from miracles. Everyone, having looked into it, could be convinced that the Moon is a complex world, in many respects similar to the Earth, that around Jupiter four small satellites address, as well as the Moon around the Earth...

The purpose of astrophysics is to study the physical nature and evolution of individual space objects, including the entire universe. Thus, astrophysics solves the most general problems of astronomy as a whole. Over the past decades, it has become a leading branch of astronomy. This does not mean that the role of such "classical" sections as celestial mechanics, astrometry, etc., is not being played. - The role of such "classical" sections as celestial mechanics, astrometry, etc., has diminished...

The asteroids square measure thus little they are thus little, they are tinpot. it's unable to allow them the form of a ball that provides the planets and their nice companions, recalling and pressing their substance. an excellent role during this case is vie by the development of runniness. High mountains on the planet at rock bottom of the bottom "sprawl", because the strength of the rocks isn't enough to resist the load of the many plenty of one cm3, and also the stone, while not crushing, while not ripping, flows, tho' terribly slowly...

Constellations are a locality of the empyrean outlined by boundaries. the full sky is split into eighty-eight-star regions (the call was created at the primary General Assembly of the International Astronomical Union in 1922 in Rome). several constellations retain their names from times of yore. Some names of constellations are connected with Hellenic language mythology, some - with subjects. There are constellations known as animal names. historically, the brightest stars of astronomers are known as the letters of the alphabet with the addition of the name of the constellation...

Astronomers have been dreaming of astronomers for a long time. One of the first and most active promoters of this idea was in the 40-50s L. Spetser from Princeton University. Back in 1946, he prepared a report (then secret) on the benefits of space observations. In 1959, 1962 and 1965, at meetings of U.S. astronomers devoted to the development of a space research program, it was recommended to begin work on the study of the project "Big Space Telescope", and in the fall of 1971, NASA organized a committee to develop this project, which began the program of the Hubble Space Telescope...
