Ordinary microscopes can see 8 times more minutely than known physical limits if miniature glass spheres are sprinkled onto samples, according to a new study.
The cheapest and most common microscopes use white light to magnify objects, but the nature of light and the limitations of our eyes mean those microscopes can’t image things smaller than bacteria. Other microscopy techniques, which use lasers, metamaterials and electron beams to image microscopic and nanoscopic worlds, can exceed such limits. But they are difficult, time-consuming and expensive to use, and they can kill live samples.
Glass microspheres about the size of red blood cells, however, described March 1 in Nature Communications, act like tiny magnifying glasses and bring normally invisible structures into sight. Stitching the microspheres’ images together with software could create unprecedented white-light photos.
“We have broken the theoretical limits of optical microscopy in white light,” said engineer Lin Li of the University of Manchester, a co-author of the study. “The surprising thing is the simplicity. One hundred dollars buys you about 100 million microspheres. Using conventional optical microscopes, almost anyone can do this.”

OP, I've been following your threads since you joined, excellent work.
Do you believe the Sun's Heliosphere could be causing the same effect? IE...magnifying stars light, making them look closer / farther away than they really are?
