1. A Galactic Star Forming Region in Infrared
... A Galactic Star Forming Region in Infrared . ... Credit: S. Carey ( SSC/Caltech ), JPL-Caltech , NASA Explanation: How do stars form? To help study this complex issue, astronomers took a deep image in infrared light of an active part of our Milky Way Galaxy where star formation is rampant. ... The image , though, taken last year by the Spitzer Space Telescope in infrared light , shows vast glowing fields of gas and dust, indicating that much of this dust is heated by forming stars. ...
2. Infrared Imaging of the Large Magellanic Cloud Star-forming Region Henize 206
Henize 206 is a region of star formation in the Large Magellanic Cloud of the approximate scale of the Orion belt and sword. Our Spitzer Space Telescope infrared images and Cerro Tololo Inter-American Observatory (CTIO) optical images show that the region is experiencing very energetic star formation. ... A few percent of the total flux from this brightest region in Henize 206 emanates from infrared peaks of subparsec scale. ...
3. APOD: 2004 August 5 - Emission Nebula IC 1396
... Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2004 August 5 . Emission Nebula IC 1396 . ... Explanation: Sprawling across hundreds of light-years, emission nebula IC 1396 mixes glowing cosmic gas and dark dust clouds . ... The filters actually block out most of the light ... but narrowly transmit wave lengths characteristic of specific glowing atoms in the nebula. ... About APOD | ...

5. An investigation of the molecular clouds of the Carina HII region/molecular
... An investigation of the molecular clouds of the Carina HII region/molecular cloud complex - First results . ... The Carina Nebula is an extremely bright southern HII region embedded in a giant molecular cloud and contains some of the most massive stars known in our Galaxy. ... Here we present the results of the initial molecular cloud observations which were made by observing the 12CO(1-0) emission with the Mopra antenna . ... HII regions -- ISM: clouds, kinematics and dynamics -- stars: formation ....
6. Near-IR Imaging of Star-forming Regions with IRAF
... We report on our ongoing project ``Infrared Study of HII Regions Associated with Small Clouds.' ... These IR data, combined with optical imaging (which will be obtained from the IAC-80 telescope), IRAS survey maps, and existing CO observations of the associated clouds, will allow us to undertake a detailed investigation of the gas-to-dust mass ratio, initial mass function and the star-formation efficiency in these complexes. ... CHECKPSF: check the PSF (Point Spread Function) model, . ...
7. GSAOI Orion Nebula Cluster Science Page
... GSAOI Home . ... Science . ... Deep imaging at J , H , and K is required to identify all stellar objects, brown dwarfs, and planetary mass objects in the central region of the Orion Nebula Cluster down to masses comparable to that of Jupiter. This is required to establish the initial mass function, i.e., the number of stars of each mass that have formed, in this region of intense massive star formation. ... The fields of the GSAOI detectors are shown as four green squares in each frame. ...
8. Astronomy HyperText Book: Interstellar Medium
Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...
