Astronomers have identified a rare moment in the life of some of the universe’s most energetic objects. Quasars were first observed 60 years ago, but their origins still remain a mystery. Now researchers at Durham University, UK, have spotted what they suggest is a “brief transition phase” in the development of these galactic giants that could shed light on how quasars and their host galaxies evolve. The new research is published in Monthly Notices of the Royal Astronomical Society.
