There’s a documentary about the universe and such narrated by Patrick Stewart called From Here to Infinity that I first saw when I was about 14. It was impressive then, but watching it now, it plays like a savagely truncated, vague, slightly updated version of Cosmos. The most interesting bit it has that isn’t touched on in Cosmos is the description of Geminga.
Geminga is a neutron star in the constellation Gemini (the word is a contraction of “Gemini Gamma Ray Source”), the remains of a star that went supernova 300,000 years ago. This was relatively recent on the timescale of the universe; recent enough, the documentary points out, to have been witnessed by our distant ancestors. For weeks after the light of its supernova reached the Earth, Geminga was visible in daylight, and cast shadows at night. It may have outshined the moon for a short time. It was so bright that its points would have stretched all the way across the sky. “The Earth must have appeared cradled in a basket of starlight,” Patrick Stewart says in the documentary.
Lucky-ass cavemen, they got to see all the cool shit.
