The episode aired around the Christmas season time. A deep space exploration team landed on a planet that had a long extinct race of beings that died during a supernova. That supernova turned out to be the bright star over Bethleham on Christmas eve. That was a cool episode but the above was what I could remember. What was the name of that episode? I haven't had any luck in finding anything about the 80's series on the net. Has this ever been in sydication or available on home video?
