New work by a team of astronomers that has yielded exquisitely precise distances of a large sample of clusters may lead to breakthroughs in understanding the expansion history of our Universe and Dark Energy.
Depending on the properties of dark energy that makes up about 70 percent of the current content of the Universe, researchers have proposed several possible scenarios of the ultimate fate of our world.
Astronomers have confirmed the
mysterious dark energy as the most comprehensive evidence yet
for the accelerated expansion of the universe, based on a
study of nearly half a million galaxies using the Hubble Space
Dark energy, habitable planets around other stars, and the mysterious nature of our own Sun, have been chosen by the European Space Agency (ESA) as candidates for two medium-class missions to be launched by the year 2017.
Astronomers from the University of Arizona (UA) and 41 other institutions are beginning the most ambitious project yet to map the three-dimensional structure of the universe in a quest to understand dark energy.
