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.

Just beyond violet lies ultra-violet (UV), which is perceivable by some birds and insects, and is typically associated with sunburn-causing light. At the other end of the spectrum, infrared (IR) lies just beyond red, and is ordinarily associated with night vision and thermal imaging. Digital cameras are capable of recording the full spectrum from 300 to 1200 nm, but doing so would not produce realistic images.
