- 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.
