Automated thermal face recognition based on minutiae extraction Forget fingerprints or iris recognition, the next big thing in biometrics will be a thermal imaging scan that maps the blood vessels under the skin of your face for instantaneous face recognition that would be almost impossible to spoof. Writing in a forthcoming issue of the International Journal of Computational Intelligence Studies, a team at Jadavpur University in Kolkata, India, explains how the pattern of blood vessels...

Heat Radiation Of Small Objects Is Beyond Planck's Equations

Vienna University of Technology Objects that are smaller than the wavelength of thermal radiation cannot radiate heat efficiently. A generalized theory of thermal radiation has now been experimentally confirmed at the level of a single object at the Vienna University of Technology. All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck's law. If, however, the radiating object is smaller than the thermal wavelength, it...

NASA SOFIA Images Massive Star Cluster

Lee Rannals for redOrbit.com - Your Universe Online NASA astronomers have taken new images of a recently born star cluster sitting in the W3 region about 6,400 light years away from Earth. The new star cluster, named W3A, is seen in the images floating in the depths of the large gas and dust cloud from which it formed. A close-up image taken by NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) shows the violent interaction zone around the massive star cluster. The...

Star Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
