This blog may perhaps be only about science and astronomy... and Carl Sagan.
I aspire to be a scientist of some kind in the future, specifically an astrophysicist.
I am 16 years old.
This is a personal blog, so don't expect a constant stream of science/Sagan 24/7. I try to keep it consistent but occasionally diverge.
Thanks for visiting :D
William Huggins (who discovered the red shift) may possibly have been the first to determine the velocities of certain celestial bodies, and thus the rate of their recession, using spectroscopy.
