cosmological constant in his General Theory of Relativity. At this time‚ we didnt even know that there are galaxies out there! What we know was that apart from our sun and planets‚ there are millions of stars everywhere and many nebula‚ which were considered as gaseous clouds. Even the best telescopes of the time couldnt reveal that many of the gaseous clouds were infect group of stars galaxies contains million of stars. It is very surprising to me that while formulating General Theory of Relativity

the beginning of the 20th century‚ physicists generally had a strong bias toward the idea that the universe was essentially unchanging. However ‚this theory does not fit with the universe phenomena which change from minute to minute‚ and stars and galaxies might be born and die .In this report ‚ we will look at one of the famous theories and greatest discoveries of this century . 1.

star‚ astronomers observe many of the billions of stars around us and see them at different stages of life‚ therefore putting together a star’s evolution. It is a star among hundreds of billions of stars within our Milky Way Galaxy‚ and our galaxy is one of billions of galaxies in the universe. The death of the star is possibly the most interesting aspect of its entire life cycle. The death of a star occurs in phases. Not all stars will visit each phase depending on the size of the star. There are

Universe and Our Galaxies The Universe and Our Galaxies Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Edwin Hubble was one of the first people to actually realise what a galaxy is‚ the measurement of the “Hubble Tuning Fork” Classification scheme shows how round or rightly wound their “arms” are. E0 means that an elliptical galaxy is extremely round‚ whilst E7 is flat. However not all galaxies can be classified

well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of extra-solar planets. As it turns out this indirect method has brought about the discovery of a new and strange material that may well constitute ninety percent of our universe. Where once we believed space was nothing more than random stars and planets and gas floating endlessly in a sea of nothingness‚ we now have proof that our galaxy and countless others are floating

dimmer‚ which means they are getting closer instead of farther away. They were able to show that dark energy has an influence on light particles and photons. When a photon passes a galaxy it falls into the gravitational pull‚ and the dark energy because it repulses gravity makes the photon pass right through the galaxy with even more energy than when it entered. These findings make dark energy completely independent of the supernova observations. Astronomers have found the first direct evidence
