When we look at the star filled night sky most of us do not realize we are looking back in time. The stars, planets and other matters in the space separated from us by tens, hundreds and thousands of light years, shows the history of the cosmic objects when the light from it started to travel from it towards the earth. Hidden among the cosmic wonders is the history of the origin of the universe waiting to be unraveled to humankind. It will not be long when astronomers can actually witness the big bang and the beginning of creation of the universe.
Astrophysicists are optimistic that the new technologies will aid them in opening new vistas on the origin of the universe and its complexities. In a series of articles published in the latest edition of Science, leading astrophysicists have explained how new technologies are helping them to unravel the cosmic web theory by which the universe is held together by dark matters.
Dark matters are difficult to be traced, as they do not reflect light waves. New technologies capable of analyzing radio waves are capable of detecting these mysterious dark matters that hold galaxies together with their gravitational attraction. In 2013 James Webb Space Telescope will be launched in the space that scientists expect will help in detecting neutral hydrogen – the remnants of the ingredients from which the first stars were born.
In 2011, the European Space Agency will launch its GALA experiment by which the stars in the universe will be mapped and their motions measured. Another important discovery the astrophysicists are waiting for is the tracking of the cosmic baryons in space using high-resolution ultra-violet optics. Baryons are protons and atomic nuclei that are present in every object big or small from stars to the tiniest insect on earth. The missing baryons will help resolve all arguments on the standard cosmological model.
