Always very informative, and has avoided some of the infotainment glitz that has infected some of the other documentary series on television. Another virtue of PBS.

One of the finest science shows to ever hit the airwaves, and still on for a reason. Constantly keeping up with the cutting edge in many fields, and showing off the brightest minds and ideas out there. I will sit my nephews down with me one of these days and watch their eyes light up when they see that science can be very cool. :)

Finally a reason to contribute to PBS. The show is well made, theoretically sound and pushes no agenda. A must watch for any stargazer.
