A astronomers England team found that there may be about 2 trillion galaxies in the observable universe, part of the universe that we are theoretically able to detect here from the earth.
The new study, led by Christopher Conselice of the University of Nottingham, used all available data, including the Deep Field Hubble, to build a 3D map of the universe around us, enabling you to trace the number of galaxies existing in different periods of history.
In addition, the team used new mathematical models that allowed them to deduce the existence of galaxies that the current generation of telescopes are not able to observe. The data offered to the astronomers the possibility of analyzing more than 13 billion years in the past, showing that galaxies are not uniformly distributed throughout the history of the universe. The official results shall be published in the Astrophysical Journal.
The James Webb Space Telescope, scheduled for launch in 2018 will more than double the number of galaxies that humans can observe. But if the latest Conselice findings are correct, that still leaves more than one trillion galaxies far from our reach.
“We are losing the vast majority of galaxies because they are very weak and distant,” said the astronomer. “The number of galaxies in the universe is a fundamental question in astronomy, and the fact that 90% of the cosmos galaxies have not yet been studied drive us wild. Who knows what interesting properties we will find when we study these galaxies with the next generation of telescopes ? ”
