In infrared astronomy, the H band refers to an atmospheric transmission window centred on 1.65 micrometres with a FWHM width of 0.35 micrometres. (in the near-infrared). Adapted from the Wikipedia article H band, under the G. N. U. Free Documentation License. Please also see...
Infrared astronomy is the branch of astronomy and astrophysics that studies astronomical objects visible in infrared (IR) radiation. The wavelength of infrared light ranges from 0.75 to 300 microns. Infrared falls in between visible radiation, which ranges from 380 to 750 nanometers, and...

In infrared astronomy, the J band refers to an atmospheric transmission window centred on 1.25 micrometres (in the near-infrared). Adapted from the Wikipedia article J band, under the G. N. U. Free Documentation License. Please also see http://en.wikipedia.org/wiki 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. For this reason, the near infrared region of the spectrum ...

One of the most common infrared detector arrays used at research telescopes is HgCdTe arrays. These operate well between 0.6 and 5 micrometre wavelengths. For longer wavelength observations or higher sensitivity other detectors may be used, including other narrow gap ...
Stratospheric Observatory for Infrared Astronomy (SOFIA) is a joint project of NASA and the German Aerospace Center (DLR) for the construction and maintenance of an airborne telescope. Universities Space Research Association (USRA) was awarded the contract by NASA in 1996 ...
The primary science objectives of SOFIA are to study the composition of planetary atmospheres and surfaces; to investigate the structure, evolution and composition of comets; to determine the physics and chemistry of the interstellar medium; and to explore the formation ...
Galactic astronomy is the study of our own Milky Way galaxy and all its contents. This is in contrast to extragalactic astronomy, which is the study of everything outside our galaxy, including all other galaxies. Galactic astronomy should not be ...
SOFIA is based on a Boeing 747SP wide-body aircraft that has been modified to carry a 2.5& meter diameter reflecting telescope in the aft section of the fuselage. This telescope is designed for infrared astronomy observations at altitudes of about ...
