The Orion complex lies about 1500 light-years distant, contains the Orion and Horsehead nebulas, and covers much of the constellation of Orion . ... About APOD | ... NASA Technical Rep.: ...

To understand the impact of low metallicities on giant molecular cloud (GMC) structure, we compare far-infrared dust emission, CO emission, and dynamics in the star-forming complex N83 in the Wing of the Small Magellanic Cloud (SMC). ... This allows us to resolve the relative structures of H2, dust, and CO within a GMC complex, one of the first times such a measurement has been made in a low-metallicity galaxy. ...

One of the goals of ALFALFA (the Arecibo Legacy Fast ALFA Survey) is that of verifying whether a significant population of optically faint, baryon rich, low mass systems exists. ... ALFALFA has easily detected the cloud VIRGOHI 21, reported by Davies et al. ... The clouds in the complex appear not to be gravitationally bound to one other, and may represent the remnant of an ancient episode of harassment. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

True Color Image Gallery: Galactic SNR | Magellanic Cloud SNR . ... Chandra Proposer's Guide pile up section ] During frame readout, the ACIS CCDs take 40 microsec to (parallel) transfer the charge by one pixel. As a result of this, each frame readout, each pixel is exposed for 40 microsec to a source (plus cosmic X-ray background) at each location along its column. ... Note also that the image does not just trail, it extends along the whole column. ... Chandra Supernova Remnant Catalog . ...
