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.

Due to the limitations of infrared technology, thermal imagers do not see under water. While an officer can use the thermal imager to help locate a person or object that is above or on the surface of the water, if the person or object submerges, it becomes invisible to the thermal imager.ue to the limitations of infrared technology, thermal imagers do not see under water.
