COMET OUTBURST:  Astronomers report that Comet Swan has suddenly increased
in brightness 4-fold, from magnitude +6 to +4.5.  This makes it a naked-eye
object in dark skies and a lovely sight through backyard telescopes.  The
cause of the outburst:  A new vein of volatile ice may have opened up in the
comet's nucleus. Solar heating transforms this freshly-exposed material into
streams of bright, reflective gas and dust. Indeed, backyard telescopes seem
to show new tendrils of gaseous material in the comet's long tail.
