Infrared radiation in the spectral distribution of a black body is usually considered a form of heat, since it has an equivalent temperature, and is associated with an entropy change per unit of thermal energy.

Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere.

The Infrared Astronomical Satellite ( IRAS ) discovered an excess of infrared radiation coming from the star, and this was attributed to energy emitted by the orbiting dust as it was heated by the star.

Infrared thermography color thermal imaging cameras ( used in formal energy audits ) can quickly document the negative thermal impact of roof-angled glass or a skylight on a cold winter night or hot summer day.

Infrared is employed to detect invisible, energy draining force fields or other threats, while night vision is especially useful to better see when playing on dark levels.

Infrared energy is continually exchanged between " hot " and " cold " surfaces until all surfaces have reached the same temperature ( equilibrium ).

The Spitzer Science Center ( SSC ), part of the Infrared Processing and Analysis Center located on the Caltech campus, is the data analysis and community support center for NASA's Spitzer Space Telescope.

Infrared is also used to observe distant, red-shifted galaxies that were formed much earlier in the history of the universe.

Infrared ( IR ) light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 0. 74 micrometres ( µm ) to 300 µm.

Infrared light is emitted or absorbed by molecules when they change their rotational-vibrational movements.

Infrared light is used in industrial, scientific, and medical applications.

Infrared spectroscopy ( IR spectroscopy ) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light.

Infrared in general is used, for instance, in TV remotes.

Infrared technology is low-cost and has the advantage of being allowed aboard.

Infrared ( IR ) light is electromagnetic radiation with a wavelength between 0. 7 and 300 micrometers, which equates to a frequency range between approximately 1 and 430 THz.

Infrared or red radiation from a common household radiator or electric heater is an example of thermal radiation, as is the heat and light ( IR and visible EM waves ) emitted by a glowing incandescent light bulb.

The high data speeds of UMTS are now most often utilised for Internet access: experience in Japan and elsewhere has shown that user demand for video calls is not high, and telco-provided audio / video content has declined in popularity in favour of high-speed access to the World Wide Web — either directly on a handset or connected to a computer via Wi-Fi, Bluetooth, Infrared or USB.

Infrared light is strongly absorbed by the hydrogen-oxygen or OH bonds.

The organisation is mission center for several key current missions ( Kepler Mission, the Lunar CRater Observation and Sensing Satellite ( LCROSS ) mission, Stratospheric Observatory for Infrared Astronomy ( SOFIA )) and a major contributor to the '" new exploration focus '" as a participant in the Orion crew exploration vehicle and Ares I crew launch vehicle projects.

Stratospheric Observatory for Infrared Astronomy ( SOFIA ) is a joint venture of the U. S. and German aerospace agencies, NASA and the DLR to make an infrared telescope platform that can fly at altitudes high enough to be in the infrared-transparent regime above the water vapor in the Earth's atmosphere.

Infrared astronomy is the branch of astronomy and astrophysics that studies astronomical objects visible in infrared ( IR ) radiation.

Infrared light is absorbed at many wavelengths by water vapor in the Earth's atmosphere, so most infrared telescopes are at high elevations in dry places, above as much of the atmosphere as possible.

The Kuiper Airborne Observatory and the Stratospheric Observatory for Infrared Astronomy use airplanes to observe in the infrared, which is absorbed by water vapor in the atmosphere.

This dependence on the polarizability differs from Infrared spectroscopy where the interaction between the molecule and light is determined by the dipole moment ; this contrasting feature allows to analyze transitions that might not be IR active via Raman spectroscopy, as exemplified by the rule of mutual exclusion in centrosymmetric molecules.

Infrared Data Association ( IrDA ) technology is a very simple form of free-space optical communications.

The Infrared Data Association ( IrDA ) is an industry driven interest group that was founded in 1993 by around 50 companies.

The near infrared ( NIR ) window lies just out of the human vision, as well as the Medium Wavelength IR ( MWIR ) window and the Long Wavelength or Far Infrared ( LWIR or FIR ) window though other animals may experience them.

The scan platform comprises: the Infrared Interferometer Spectrometer ( IRIS ) ( largest camera at top right ); the Ultraviolet Spectrometer ( UVS ) just above the UVS ; the two Imaging Science Subsystem ( ISS ) vidicon cameras to the left of the UVS ; and the Photopolarimeter System ( PPS ) under the ISS.

Infrared radiation with wavelengths just longer than visible light, known as near-infrared, behaves in a very similar way to visible light, and can be detected using similar solid state devices.

* Active Infrared, combines infrared illumination of spectral range 700 – 1, 000 nm ( just below the visible spectrum of the human eye ) with CCD cameras sensitive to this light.

Harbaugh flew as a mission specialist and was responsible for operation of the RMS and the Infrared Background Signature Survey ( IBSS ) spacecraft, and he was one of two crewmen trained for EVA in the event of a contingency requiring a space walk.

It is one of the three asteroids discovered with data from Infrared Astronomical Satellite in 1983, and was named in honour of the satellite.

In 1979, a National Research Council of the National Academy of Sciences report, A Strategy for Space Astronomy and Astrophysics for the 1980s, identified a Shuttle Infrared Telescope Facility ( SIRTF ) as " one of two major astrophysics facilities be developed for Spacelab ," a Shuttle-borne platform.

It presented one of the first Adaptive Optics system available to the astronomical community, ADONIS: ADaptive Optics Near Infrared System in the 1980s.

Integrates four USB ports, one ATA-66 UDMA controller, one Infrared communication port, one AC ' 97 controller, one SMBUS controller, one LPC port, as well as GPIO, Power Management, and legacy functional blocks.

Infrared has significant limitations ; one being that it is line of sight only ; there had to be a clear space between the IR port and the controller.

This was one of the first uses of Infrared in combat and the attack, although limited, was a resounding success.

As of 2011, the engineers are working on the High-resolution Airborne Wideband Camera ( HAWC ), which will be an integral part of Stratospheric Observatory for Infrared Astronomy ( SOFIA ).

The Infrared Space Observatory ( ISO ) was a space telescope for infrared light designed and operated by the European Space Agency ( ESA ), in cooperation with ISAS ( part of JAXA as of 2003 ) and NASA.

It is derived in part by the Mars Express High Resolution Stereo Camera ( HRSC ) and the Rosetta Optical, Spectroscopic and Infrared Remote Imaging System ( OSIRIS ).

Infrared homing refers to a passive missile guidance system which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it.
