I can remember when reviews of digital cameras (including phone cameras) 
would decry the emphasis on more and more megapixels, saying there were 
other factors that went into the quality of the image, too.

Well, astronomers might beg to disagree. They have just commissioned the 
world’s highest-resolution digital camera, at 3.2 gigapixels, as part of 
the Vera C Rubin telescope in the Atacama Desert in Chile.

Who was Vera Rubin? She collected data on the peculiar movements of stars 
in the outermost parts of galaxies that led to the inescapable conclusion 
that 90% of the Universe is made of “dark matter” -- matter we cannot see 
directly, but whose gravitational influence can be seen in those stars.
