It is named after an American Astronomer, Edwin Hubble who made important astronomic discoveries in the 1920’s. Pictures taken by the Hubble Telescope include: stars surrounded by disks, galaxies, colliding galaxies, and evidence that most galaxies have black holes in their centre. The Hubble Telescope is in orbit about 380 miles above…

Is Scientific Progress Inevitable_

I read the article “Is Scientific Progress Inevitable?” which was written by Andrew Irvine on 2006. It was published in the book In the Agora: The Public Face of Canadian Philosophy. The main idea of the article is scientific progress is not inevitable. At the first part of the passage, the author used his own his experience that he took his daughter to see a medicine wheel; he used what he saw to let us know these structures have been…

Current Research in Astronomy

For many astronomers, Adaptive Optics is something like a dream coming true. Since 1609 and the first observations of celestial bodies performed with the help of an optical telescope, astronomers have always fought to improve the resolving power of their instruments. For a long time, engineers have trimmed the optical quality of the telescopes, until they finally reached the barrier set by the atmospheric turbulence. At that point, the intrinsic quality of the site became a major issue to establish…

The Origin of Modern Astronomy

The fourth chapter “The Origin of Modern Astronomy” discusses the development of astronomy as scientific field. The author embraces the history from the very beginning, when humans showed curiosity about the lights in the sky, and comes up with modern innovations. From the very first stages of development astronomers tended to understand the movements of the Sun and the Moon, planets and other events, whereas others tended to make precise measurements and to describe the motions of heavenly bodies. Actually,…

Introduction to Astronomy

The life cycle of a star is a process that is not only beautiful but, fascinating to those fortunate ones who have the chance to study the subject. To the uneducated soul, gazing upon the night sky wondering what is out there is not a common thing. But being able to learn about what is really out there and how it became, that my friends, is truly an amazing task. One has to wonder just how we know what type…

Life and Work

Brahmagupta is believed to have been born in 598 AD in Bhinmal city in the state of Rajasthan of Northwest India. In ancient times Bhillamala was the seat of power of the Gurjars.

He was the…

What Has Astronomy Done for you Lately

In the article “What has Astronomy done for you lately” it opens my eyes up to all the relative ways astronomy contributes to our society today. It is mentioned in the article that the funding for space launching and research for the program estimates around $8 billion. During these stringent economic times some question regarding the funding of these programs based of the actual need and benefit. Many people seemed to think that there was nothing that the universe actually…

Cosmology in Milton’s Paradise Lost

The Oxford English Dictionary defines “cosmos” as “the world or universe as an ordered and harmonious system,” from the Greek, “kosmos,” referring to an ordered and/or ornamental thing. When God created the world he had this in mind. To have a harmonious system in the universe where everything can live in peace and free of all worry. God was on top and everything was peaceful. Until the angles in Milton’s Paradise Lost had a fight. After the fight God banished…

Current Event in Astronomy

The best of the fire-works which lit up the sky, cannot match this spectacular show. The beauty of these fire-works is not even comparable to the beauty of this show. The fire-works travel from earth to space while the objects of this show fall from space to earth. The host of fire works which adorn the sky is man, whereas the host of this show which will adorn the sky on the night of 12 August 07 is mother nature….

Answers to Questions in Astronomy

1. How do astronomers measure the distances to galaxies and how does that allow the sizes, luminosities and masses of galaxies to be determined? A distance indicator is an object within a galaxy that functions as a marker to that galaxy. It may be a Cepheid star, globular cluster, H II region, planetary nebula or supernova. The distance to a galaxy, especially if it is very far away, is approximated by employing the Hubble Law which is expressed as Recession…
