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.

Most radiology imaging studies use x-rays to visualize what lies inside the body. For example, a chest x-ray allows the doctor to see through the skin and study the heart and lungs. Modern x-rays are very safe, but do expose the body to some x-ray radiation. Magnetic resonance imaging (MRI) is a different method of looking inside the body. Instead of x-rays, the MRI scanner uses magnetism and radio waves to produce remarkably clear pictures. The powerful magnetic field causes the hydrogen ions in the body to become magnetized and line up in a certain order.
