2. APOD: November 19, 1996 - Fractal Interstellar Dust Up-Close
... Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. November 19, 1996 . Fractal Interstellar Dust Up-Close . ... But nobody really knows what a typical interstellar dust grain looks like. By studying how dust absorbs, emits, and reflects light, astronomers do know that interstellar dust is much different than the cell and lint based dust found around a typical house. ...

3. Research - Compact high-velocity clouds around the Milky Way
... High-velocity clouds (HVCs) were discovered by Muller, Oort & Raimond (1963) in the 21-cm line emission of neutral, atomic hydrogen. They are gas clouds which are characterised by high radial velocities incompatible with a participation in the rotation of our Galaxy. ... This suggestion was seized by Braun & Burton (1999) who identified 66 compact high-velocity clouds (CHVCs) with positional and kinematic characteristics being compatible with a distribution across the entire Local Group. ...

5. The Ever-changing Circumstellar Nebula around UW Centauri
We present new images of the reflection nebula surrounding the R Coronae Borealis Star, UW Centauri. ... Instead, the morphology of the nebula appears to change as different parts are illuminated by light from the central star that is modulated by shifting thick dust clouds near its surface. ... In this way, the central star acts like a lighthouse shining through holes in the dust clouds and lighting up different portions of the nebula. ... ADS Citation Query . citations = 21 . ...

8. APOD: 2001 January 23 - Spherical Planetary Nebula Abell 39
... 2001 January 23 . Spherical Planetary Nebula Abell 39 . ... Planetary nebula Abell 39 , now six light-years across, was once a sun-like star's outer atmosphere expelled thousands of years ago. The nearly perfect spherical nature of Abell 39 allows astronomers to accurately estimate how much relative material is actually absorbing and emitting light. ... Abell 39 lies about 7000 light years away, although several galaxies millions of light years away can be seen through and around the nebula. ...

17. 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. ...

20. Polar Orbiting Satellites
Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...
