Galileo and 400 Years of Telescopic Astronomy (Astronomers' Universe)
Peter Grego, David Mannion
Format: PDF / Kindle (mobi) / ePub
In 1609 Galileo first used his telescope to kick start the science of observational astronomy - an event that proved to be of enormous historic, scientific, and cultural importance. Galileo and 400 Years of Telescopic Astronomy will feature the life and achievements of Galileo, around which has pivoted the story of four centuries of telescopic astronomy. The book will detail how astronomy has progressed through four centuries and contain glimpses of future space research and astronomy goals. Uniquely, interwoven with the text will be a range of practical projects for backyard astronomers in which to participate, projects that serve to illustrate many of Galileo's scientific discoveries.
Was just one of a broader mass of stars contained within a vast star system containing countless thousands of stars. In the mid-eighteenth century, Thomas Wright was most perceptive in suggesting that the band of the Milky Way was caused by our view from deep within a vast, flat, millwheel-shaped star system; he found no evidence that the Sun lay at the Galaxy’s center, or that the system was finite in breadth.

Sun; he was off by several orders of magnitude. The Sun is actually 400 times further away than the Moon and is 400 times the Moon’s diameter (109 times the diameter of Earth and 1,300,000 times Earth’s volume). Eratosthenes Takes Measures Mathematics and geometry proved invaluable tools in attempting to understand the scale of the Universe. Eratosthenes of Cyrene (276–194 BCE) used observation and trigonometry to derive a number of astronomical distance measurements, among them a remarkably.

Radiation is in our line of sight (like a lighthouse beam). The pulses are extremely regular and range from milliseconds to several seconds. There are more than 1,600 pulsars that have been observed in our galaxy, the first discovered by Jocelyn Bell in 1967. The Crab Nebula which is the supernova remnant of the supenova seen in 1054 by the Chinese, has a 33-ms pulsar that has been observed at all wavelengths from radio to gamma rays.
