Cheap Astronomy - Dear CA Ep. 118: Reflections

Self-consciousness.


Dear Cheap Astronomy – Selfies in space.


Buzz Aldrin claims to have taken the first selfie in space in
1966, where he fixed a Hasselblad camera on the hull on Gemini 12
and then leant back before triggering the camera. Later on, in
1969, Neil Armstrong took an accidental selfie – the only still
photo of him on the Moon where he and his camera are reflected in
Buzz Aldrin’s visor.


 


Dear Cheap Astronomy – Is Hawking Radiation real?


Long-term listeners are probably familiar with Cheap Astronomy’s
tendency to go a bit ranty in the face of any unreasonable
acceptance of cosmology hypotheses. So, for example, the Universe
is not only expanding but that expansion is accelerating. Sounds
extraordinary, but there’s sound observational evidence to back
it up.
