For the first time, astronomers have seen the image of a distant quasar split into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as early as 1970, but the first evidence for one now has come from the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope system.
An international team of astronomers has found the largest known structure in the universe - a group of quasars four billion light years across.
Researchers at MIT, the California Institute of Technology, and the University of California at San Diego have peered so far back in time that they've found matter that pre-dates the creation of heavy elements.
Astronomers at the European Southern Observatory (ESO) have identified the biggest quasar outflow, a type of high energy explosion surrounding a massive black hole, to date.
Scientists are currently unable to navigate deep space the way Columbus sailed and charted the New World or Lewis and Clark mapped the West.
Long-theorized, but never before seen, the dark galaxies of the early universe have now been directly observed by ESO's Very large telescope (VLT).
Astronomers have found an enormous cloud of water - containing 140 trillion times as much as is found on Earth - floating around a distant quasar.
