Scientists Might Be Getting Closer to Knowing Dark Energy

A new space telescope is being launched by the European Space Agency to help scientists build a 3D map of the universe by photographing billions of galaxies up to 10 billion light years away – across more than a third of the sky. Around 95% of the universe is ‘dark matter’ or ‘dark energy’ which doesn’t fit into our cosmological models. The super-sensitive telescope will effectively enable us to look back in time to how distant galaxies looked 10 billion years ago and to see how dark energy accelerated the expansion of the universe.
