The Kavis Alpha sector is the site of an unusual neutron star/red giant star system. The neutron star goes through a cycle of sucking matter from the nearby red giant, and explosively expelling the matter into space, every 196 years.

In 2366, Doctor Paul Stubbs recorded this historic event, from the USS Enterprise-D, using a customized probe known as "The Egg". (TNG: "Evolution")
