   This *may* have to do with the Geminga object, recently revealed by
   Rosat and GRO to be a pulsar with an age of about 300,000 years.  The
   best estimate of the distance is around 100 light-years, so is quite
   close in astronomical terms.

Yes, they're talking about Geminga. See a recent Science News for
more.
