Infrared spectroscopy — (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a range of techniques, the most common being a form of absorption spectroscopy. As with all spectroscopic techniques,… … Wikipedia
Infrared astronomy — is the branch of astronomy and astrophysics which deals with objects visible in infrared (IR) radiation. Visible radiation ranges from 400 nm (blue) to 700 nm (red). Longer wavelengths than 700 nm but still shorter than microwaves are called… … Wikipedia

Near infrared spectroscopy — (NIRS) is a spectroscopic method utilising the near infrared region of the electromagnetic spectrum (from about 800 nm to 2500 nm). Typical applications include pharmaceutical, medical diagnostics (including blood sugar and oximetry), food and… … Wikipedia
H II region — An H II region (also known as emission nebula) is a cloud of glowing gas and plasma, sometimes several hundred light years across, in which star formation is taking place. Young, hot, blue stars which have formed from the gas emit copious amounts … Wikipedia
Solar transition region — The solar transition region is a region of the Sun s atmosphere, between the chromosphere and corona. It is visible from space using telescopes that can sense ultraviolet. It is important because it is the site of several unrelated but important… … Wikipedia
