Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

Here, Galileo took this crude device ... aberration was a limiting factor in refracting telescopes, and that this could be overcome by making lenses with longer focal length, resulting in monsters ...

Now, a team of engineers from the University of Utah has developed a revolutionary flat telescope lens that captures color accurately while detecting faint starlight from distant objects. This ...
