Astronomers discover new way to measure Universe
(PhysOrg.com) -- Astronomers at Copenhagen's Niels Bohr Institute have found a new way to measure 
distances. This may not sound like much, but working out how far away something is, is one of the toughest fundamental problems in astrophysics and is central to cosmology as it allows scientists to work out the age of the Universe and what it’s fundamental properties are. Because their new method uses quasars, some of the brightest objects known, scientists say they will be able to determine distances much further than achieved to date, paving the way to a better understanding of dark energy.
