Winter solstice and Neal deGrasse Tyson

Funny how today on winter solstice has been one of the brightest days during this winter. Not only sun shined on Espoo but it also snowed bringing us a white ground!
Lately I’ve been watching Neal deGrasse Tyson videos on YouTube. Following video is one of the many interesting Neal Tyson videos, this time interviewed by Stephen Colbert. Also, check Cosmos: a SpaceTime Odessey.
