... 2001 September 10 . Galactic Center Flicker Indicates Black Hole . ... CXO , NASA . Explanation: Why would the center of our Galaxy flicker? Many astronomers believe the only credible answer involves a black hole . ... Only one known type of object can fit so much mass in so small a volume: a black hole . This short flicker therefore provides additional evidence that a black hole does indeed reside at our Galaxy's center . ... About APOD | ... NASA Technical Rep.: ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...

... 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. ...

Central Astronomical Observatory at Pulkovo of Russian Academy of Sciences PUL Analysis Center Pulkovo IVS Analysis Center (PUL) 2009 Annual Rep ort Zinovy Malkin, Natalia Miller, Elena Popova Abstract This report briefly presents the PUL IVS Analysis Center activities during 2009 and plans for the coming year. The main topics of the investigations of PUL staff in that period were ICRF related studies, computation and analysis of EOP series, and VLBI2010 related issues. ...

This new image shows the Large Magellanic Cloud galaxy in infrared light as seen by the Herschel Space Observatory and NASAтАЩs Spitzer Space Telescope. In the instruments' combined data, this nearby dwarf galaxy looks like a fiery circular explosion. Rather than fire, however, those ribbons are actually giant ripples of dust spanning tens or hundreds of light-years. ... The brightest center-left region is called 30 Doradus, or the Tarantula Nebula, for its appearance in visible light. ...

... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...

The Optical Solar Sensor (OSD) has been designed to determine the direction towards the center of the Sun's visible disc. The direction to the Sun is computed in the instrument coordinate system relative to the pixels' position on the linear CCDs illuminated with the light passed through the incoming coding mask. The OSD coding mask has three groups of slits with three slits in each group. This mask configuration provides for reliability increase as well as for the required accuracy. ...

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. ...
