... Глава 4. ... Торможение небесных тел . ... Это относится и к небесным телам Солнечной системы. ... На основании этого можно сделать вывод, что торможению подвергаются и все небесные тела Солнечной системы, как и других звездно-планетных систем, при наступлении галактических зим, когда Солнечная система проходит в своем обращении вокруг центра Галактики через спиральные рукава, а также через плоскость Галактики между рукавами или через газово-пылевые облака, встретившиеся на периферии Галактики. ...

This was made possible by Johannes Kepler's understanding of the orbital behavior of celestial objects (his now famous three laws of planetary motion), careful inspection of Kepler's predictions by an English astronomer - Jeremiah Horrocks , the wisdom of Edmond Halley who not only discovered a comet but developed the first detailed plan for calculating the AU from transits of the sun, and a concept called "parallax"; . ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ...
