Friday, August 2, 2019 Infrared (IR) is a type of light with a wavelength just beyond the visible spectrum. It is used in many fields, including medicine, astronomy, and military applications. In medicine, infrared radiation is used to provide imaging of the body and to detect cancer, fractures, and other diseases. In astronomy, infrared light is used to study the composition of the universe and to observe distant galaxies. In military applications, infrared can be used for night vision and for target acquisition. In this section, you can find news, articles, and videos about infrared technology and its applications.
Astronomers are observing star-forming regions in our galaxy with NASA’s flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments required to create the largest known stars, which tip the scales at ten times the mass of our own Sun or more.
