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.

March 31, 2015. Infrared cameras photograph heat rather than objects. The camera is a heat-sensor that registers different temperature levels and converts them into a film or video image. Most cameras use digital imaging, but some use chemical infrared film. Cameras range from simple point-and-shoot types to expensive models with detailed, higher-resolution imagery. A thermal image can show where a building leaks heat.
