Galileo and 400 Years of Telescopic Astronomy (Astronomers' Universe)



Publisher: Springer 2010 ISBN 1441955704 PDF 170 pages 15 MB

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.

Imagine yourself living 400 years ago, right before the telescope was first used by Galileo to look up into the skies and find unforeseen wonders. You probably believed, with most of the known world, that Earth was at the center of the magnificent parade of planets and stars above you, and the Sun’s purpose in journeying across the sky was to give Earth daylight and warmth. Suddenly, though, your world is turned upside down. The Church, all powerful in its doctrines and teachings of the times, continues to support theories that don’t fit the facts presented by scientists. Scientists in their quest for truth must hide their findings or risk the harsh penalties imposed by the Church. We have gone from a comforting Earth-centered universe to a tiny floating spec in a gigantic cosmos, barely a comma in a lengthy treatise. And we have gone there in a blink of an eye. We may have lost our central position in the universe, but Grego and Mannion show us how much we have gained in understanding the universe around us. And we are only at the beginning of our journey. Their words help us to discover our place again and how we got there and what we might expect to learn in the centuries to come.

Bulan Senyum Mata Satu

Assalamualaikum. Maaf kerana lama menyepi kerana komitmen terhadap pelajaran d kampus. Terlebih dahulu saya ingin mengucapkan selamat hari raya, maaf zahir dan batin. Pada masa raya seperti biasa aktiviti yang biasa disertai adalah cerapan anak bulan syawal yang biasanya memang ditunggu ramai. Selain itu, terdapat keistimewaan pada aidilfitri tahun ini kerana mencerap langit malam pada hari raya kedua.

Sebenarnya cerapan langit malam ini adalah bertujuan untuk melihat fenomena yang dikatakan "Bulan Senyum". Tetapi oleh kerana keadaan langit pada waktu itu amat baik sekali, pencerapan diteruskan dengan objek lain seperti musytari. Tetapi jaluran Musytari tidak dapat dilihat dengan jelas kerana kedudukannya yang berada sangat rendah di mana hampir kepada pencemaran cahaya. Di bawah terdapat beberapa gambar yang telah diambil pada hari tersebut:


Planet musytari jika dilihat melalui teleskop meade LX200 dapat dilihat bulannya.
