Are there any natural mirrors?
Natural mirrors have existed since prehistoric times, such as the surface of water, but people have been manufacturing mirrors out of a variety of materials for thousands of years, like stone, metals, and glass. These rays are reflected at an equal yet opposite angle from which they strike the mirror (incident light).

Can We cool the Earth by sending mirrors into space?
The record-breaking temperatures of the past few years are getting more people thinking about bigger solutions to climate change. Ideas once thought of as wacky are now receiving careful consideration, including an idea that sounds straight out of science fiction: cooling the earth by launching reflective mirrors into space.
Is it possible to make a giant mirror in space?
While a giant space mirror isn’t currently possible with today’s tools, technology is in fact catching up to science fiction, and the idea seems less outlandish than it did a decade ago. Will an enormous mirror someday be the world’s last hope to stop global warming?
Can we see past in a mirror?

Actually there’s a tiny mirror facing Earth on Moon.
Is there a mirror in the universe?
In fact, something like such a mirror do exist in the universe. Dust arround progenitor of SN 1572 still reflects light od the outburst. Spectral analysis of the light confirm that the supernova was of Ia type (the fact established long before from light curve of the supernova).
