It is said that every phenomenon leaves a clue or a mark. So did the first stars. Or you may call it the first object of the universe. To colonize the early universe, they left a weak glimmer. Astronomers detected it by using NASA’s Spitzer space telescope and careful calculations. Alexander Kashlinsky, at the space agency’s Goddard space centre, in Maryland, was able to pick out an infrared radiation pattern believed to be the remnant signature of energy from the universe’s first clusters of stars. Unlike the ones we witness today, the first stars are thought to have been lightweight, with no heavier elements such as carbon and oxygen. They were also gigantic: more than 100 times bigger than our sun. Only a 100 million-year-old, they were born when the universe was very young. Now, more than 13 billion years after the death of the stars, the astronauts claim to have spotted the ancient flickering of these bodies. It was then, after the fading embers of the theorized Big Bang gave way to millions of years of pervasive darkness, the universe came alive. The stars are appearing red due to the expansion of the cosmos, because the stars are so far away with the light still traveling towards us.
