As if to make up for the departure of the glamorous Hale-Bopp comet, astronomers have re- leased a flurry of reports on other celestial matters. Refined measurements of the ages of stars appear to be resolving the seeming paradox in which some stars appeared to be older than the universe it- self. A new observation offers the first concrete clues regarding the nature of the mysterious flashes of energetic radiation known as gammaray bursts.
But by far tile most startling and tentative finding is that the universe has a preferred orientation. Such directionality would challenge one of the basic tenets of physics and astronomy, taken for granted by Einstein, Newton and even Kepler. These giants all assumed that space possesses a property called rotational symmetry: spin a chunk of cosmos sideways or flip it upside down, and measurements of events within it yield precisely tile same results.

A. rotational symmetry.
B. charged particles.
