Dear friends, you must have heard about the Big Bang theory, which explains how our universe came into being. According to this theory, about 12 to 14 billion years ago, the universe as we see it today was only a few millimetres across. It has since expanded from a hot, dense state into the vast and much cooler cosmos we currently live in. This theory is a part of cosmology ' a subject that studies the formation, organisation and evolution of the universe. Now, if that sounds interesting, join me in exploring this website: http://map.gsfc.nasa.gov/m_uni

The site, created by the American space agency Nasa, equips you with an in-depth understanding of the Big Bang theory. Teachers, students or just about anyone who is interested in the theory will have a great time going through this easily-navigable website, which puts a premium on content rather than design.

At the homepage, you will notice that the website is divided into five sections, which are listed on the left side margin along with a table of contents at the bottom of the page. These five sections offer you answers to such interesting questions about our universe as 'How fast is the universe expanding', 'What is the shape of the universe', 'How did we get from the Big Bang to the human search for extraterrestrial life', 'Will the universe continue to expand forever, or will it eventually collapse'

Apart from this, you can read up on such topics as the first objects in the universe, the Milky Way, and the life cycle of stars. And don't forget to check out the image gallery. You'll find some exclusive pictures here, which only Nasa can provide. Happy surfing!
