... The TRACE images may be used without restrictions in publications of any kind. ... These two images, taken on 18 November 2000 at 15:54UT and 16:11UT, respectively, show such an event: the red circle in the image to the left shows a region where many loops are cooling, with bright loop tops (the intensity scales with the square root of the image to reduce the dynamic range). ...

3. Phil Plait's Bad Astronomy: Bitesize Astronomy
... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

6. WFPC2 Bright Star Avoidance Regions
... WFPC2 Home . ... Bright stars near the WFPC2 field of view can cause various artifacts to appear in science images. ... When writing Phase II proposals, observers will sometimes attempt to avoid bright stars by placing them in the un-imaged "L" shaped region adjacent to CCD PC1, or in the region just outside the nominal field of view. ... In both cases the optics can image this light back onto the CCD's. Bright stars must be placed at least 10 arcseconds outside the field to avoid artifacts. ...

It was in the general region of Gamma Ophiuchi, although the sky was too bright, with too few stars visible, for me to get an accurate position. AHA, you'll say - an Iridium Flare! ... BUT - they usually appear in roughly the same quadrant of the sky as the predicted flares, since the Sun-Earth-Satellite angle is similar. ...

... This image shows clearly the 3-D structure of this star formation region: a large cavity, created by the radiation pressure from new-born stars located in the brightest area of the image, lies within a huge cloud of dust and gas. Identified as a truly indepedent star cluster, NGC 1980 is associated with this well-studied star formation region, around the brightest star seen at the bottom of this image, Iota Ori. ...

15. http://www.eso.org/public/news/eso1304/kids/
... This beautiful new image shows a glowing cloud of cosmic dust (called a nebula) sitting boldly against a backdrop of shining stars. To the naked eye, thick clouds like these appear empty and dark, but some are actually home to the brightest nebulae and hottest young stars in the Universe! Stars are made of gas, so it is no surprise that they are born inside thick gassy clouds. But the clouds that give birth to stars also block our view of them growing within. ...

16. The Sun's Corona
The Sun's corona . ... For instance, short "plumes" rising from the polar regions of the Sun look very much like field lines coming out of the end of a bar magnet, and they therefore suggest that the Sun, in addition to the intense fields of sunspots, also has a global magnetic field like the Earth's. Arches above the . Sun's surface . ... It is brightest near sunspots, whose arched field lines apparently hamper the outflow of solar wind which carries away energy and helps cool the corona. ...

An increase in star brightness is followed by a decrease in asphericity and wind velocity to the point where stationary and even accreting fraction of the wind appears in extremely bright objects together with a flowing out fraction. ... Based on an analysis of observations obtained with BTA and on the published data it was found that degree of abnormality of energy distribution in continuum of magnetic chemically peculiar stars increases with an increase of their rotation period. ...
