1. APOD: 2016 February 28 - IC 1848: The Soul Nebula
... 2016 February 28 . IC 1848: The Soul Nebula . Image Credit Copyright: Roberto Colombari . Explanation: Stars are forming in the Soul of the Queen of Aethopia. ... The Soul Nebula houses several open clusters of stars , a large radio source known as W5 , and huge evacuated bubbles formed by the winds of young massive stars. Located about 6,500 light years away, the Soul Nebula spans about 100 light years and is usually imaged next to its celestial neighbor the Heart Nebula (IC 1805). ...

2. Star Forming Region S106
... Born only about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), featured here . A large disk of dust and gas orbiting Infrared Source 4 (IRS 4), visible in brown near the image center, gives the nebula an hourglass or butterfly shape. S106 gas near IRS 4 acts as an emission nebula as it emits light after being ionized , while dust far from IRS 4 reflects light from the central star and so acts as a reflection nebula. ...

4. 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. ...

9. 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. ...

10. Black aurora [Oulu]
spaceweb@oulu.fi - last update: 18 February 1997, 1100 UT (RR) . Black aurora is a lack of auroral emission in a small, well-defined region within an otherwise uniform, diffuse background or within auroras exhibiting a degree of shear behaviour intermediate between that of diffuse and discrete aurora (e.g., Davis, 1978). It appears to be a common feature of the midnight sector during late substorm recovery phase (Trondsen and Cogger, 1997). ... 30 , 371-380, 1978. ... 102 , 363-378, 1997. ...

13. http://star.arm.ac.uk/~ambn/abstract280.html
The power specta for line intensities of several lines formed in the upper transition region around 100,000 to 250,000K are presented. A period of ~5 min. is clearly present in lines due to O III, O IV and O V. In one dataset a period approaching 10 min. is present for ~10 min. ... In all datasets examined, there is excess power below 1mHz everywhere along the slit, although the observed periods do not always come from the most intense regions. ... In all regions, the 5.0mHz power peak is smaller. ...
