In the next year and a half, there will be four blood moons, which is a rare phenomenon that astronomers have a name for: a tetrad. Tetrads come and go, according to NASA lunar eclipse expert Fred Espenak. Some centuries have several, and the 21st century will have eight. However, there were none between 1600 and 1900.
Thermal Imaging really canât see through walls but at Infrared New England we can do the next best thing.We use the most sensitive thermal imaging cameras available in the Infrared industry.High-resolution equipment combined with 35 years of building experience and building science background gives us the ability to âalmostâ see through walls.e use the most sensitive thermal imaging cameras available in the Infrared industry.

Answer Your brain can't see heat, ultraviolet light, radiowaves,  X-Rays, etc. with your naked eyes, because these different kinds of  light's wavelengths are either too lon â¦ g or too short for your naked  eyes to see. So that is why you can't see infrared.he two ligh energy waves that you can't see are ultra-violet (UV), and infra-red (IR).  Ultra-violet light waves are measured at 380nm and below, infra-red light waves are â¦ 750nm and above.  Normal light that you can see resides between these two regions.
