Astronomy: Discovering the Universe
Astronomy is an age old science and involves the exquisite study of celestial objects.The detailed study of the stars, planets, galaxies and comets are applied in the understanding of the cosmic background radiation that takes place consistently beyond the atmosphere of the Earth. The revelations have largely affected and influenced man's understanding of evolution, meteorology and the laws of physics. The movements observed have enabled scientists to gain a deeper understanding of the celestial objects as part of and the origin of the development of the universe. Previously, the Earth was believed to be the center of the universe and was studied as the 'geocentric model' of the universe. Nicholas Copernicus is a famous Polish astronomer who is well known for his Copernican theory, which states that the sun is the center of the universe and the earth revolves around it and completes one revolution in a year. Tycho Brahe was a Danish astronomer who is supposed to have made the most accurate astronomical observations about measurements of the solar system and over 700 other stars. Galileo Galilei was an Italian physicist and an astronomer. His achievements include improvements to the telescope, noteworthy astronomical observations, and support for Copernicanism. Galileo has been called the "father of modern observational astronomy." During the Middle Ages, astronomy was mostly stagnant in medieval Europe, at least until the 13th century. However, astronomy flourished in the Islamic world and other parts of the world. This led to the emergence of the first astronomical observatories in the Muslim world by the early 9th century. In 964, the Andromeda Galaxy, the nearest galaxy to the Milky Way, was discovered by the Persian astronomer Azophi and first described in his Book of Fixed Stars. The SN 1006 supernova, the brightest apparent magnitude stellar event in recorded history, was observed by the Egyptian Arabic astronomer Ali ibn Ridwan. Galaxies are spiraling whirlpools of matter and energy, which are like small oasies in the vast empty spaces of our universe. We live in one such galaxy, which we call the Milky Way. Black Holes form when stars much larger than our Sun run out of their fuel and collapse under their own gravity to zero volume, forming a hole in the fabric of space time. Pulsars are rotating neutron stars with huge magnetic fields, which emit electromagnetic radiation. They are formed from the core of a star exploding in a supernova. Quasars (Quasi-stellar objects) were first mistaken to be stars, but later they were discovered to be galaxies. They have a very high redshift, which means that they are traveling at a speed close to the speed of light. Heritage of Bangladesh
Bangladesh, being a small country, has its heritage and its rich culture, tradition, history and beauty which make up a rich civilization. The Sompura Mahavihara, famously known as Paharpur Vihara, was one of the very first universities of the world. It was built by Dharmapala as an institution for education. It is indeed the largest vihara of the Indian subcontinent. A stupa in the middle surrounded by an 177- roomed Vihara at Naogaon district was declared a World Heritage Site in 1985. Apart from Paharpur, we also have Shalvan Vihara (known as Mainamati) at Comilla.The Kantajir temple is one of the very famous Hindu symbols of architecture situated in Dinajpur district, with some of the finest terracotta works. Another Mughal artifact is Lalbagh Fort. It is situated by the river Buriganga.It contains the tomb of Pari Bibi, audience room and Hammamkhana. In British times, the artifacts and heritage turned into different patterns. One of them is Ahsan Manjil. It is also situated by the river Buriganga. Nawab Khwaja Enayetullah named it. It played a very important part in our political movement. In 1961, the famous architect Louis I Kahn designed one of the biggest structures in the world. It is our Parliamentary building, symbol of democracy and freedom. Situated on 200 acres of land, the building was inaugurated in 1982. It is considered as one of the top ten architectures of the 20th century. Bangladesh is also rich in natural beauty. Cox's Bazar is the longest sandy beach in the world. About 125km long, this beach is the most attractive tourist spot of the country. It is named after Captain Hiram Cox. The Sundarbans, the largest halophytic mangrove forest situated in the southern part of the country. Its area is 10,000 sq.kms, of which 6000 sq.km is in Bangladesh. The Ganges, Brahmaputra and many rivers surround the forest. Royal Bengal Tiger, crocodiles and deer are very famous in the region. UNESCO declared it as a WHS in 1997and now it is one of the top 21 natural wonders of the world. We should be proud of our culture, tradition, and heritage and present them in that light before the world.
