We describe the architecture of a general cross-comparison engine capable of spatially matching sources in one astronomical source catalog with those in another. ... Support is provided for common catalog formats and data sources (e.g. local disk, database servers), and the addition of support for custom data formats and sources is simplified by the modular architecture employed. ...

... October 1, 1999 . New Stars In 30 Doradus . ... Explanation: Compare these matched Hubble Space Telescope views (visible-light on top; infrared on bottom) of a region in the star-forming 30 Doradus Nebula . Find the numbered arrows in the infrared image which identify newborn massive stars. For example, arrows 1 and 5 both point to compact clusters of bright young stars . ... Perhaps even more remarkable are the infrared bright spots indicated by arrows 6 and 7. ... About APOD > . ...

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...
