Washington, Nov 1: Astronomers have probed the collision of two large clusters of galaxies, using NASA’s Chandra X-ray Observatory and Compton Gamma Ray Observatory, to search for evidence of primordial antimatter.

Antimatter is made up of elementary particles, each of which has the same mass as their corresponding matter counterparts - protons, neutrons and electrons - but the opposite charges and magnetic properties.

When matter and antimatter particles collide, they annihilate each other and produce energy according to Einstein’s famous equation, E=mc2.

According to the Big Bang model, the Universe was awash in particles of both matter and antimatter shortly after the Big Bang.

Moscow - The splurge of oil profits feeding Russia's years of growth has turned sticky with falling production and energy prices.

This double whammy is threatening to undercut the government's economic policy as the industry that is its main source of revenue takes a battering from the country's worst financial crisis in a decade.
