The Spitzer Infrared Nearby Galaxies Survey (SINGS) is carrying out a comprehensive multiwavelength survey on a sample of 75 nearby galaxies. The 1-850 ЮМm spectral energy distributions (SEDs) are presented using broadband imaging data from Spitzer, 2MASS, ISO, IRAS, and SCUBA. ... Spitzer's excellent sensitivity and resolution also allow a detailed investigation of the infrared SEDs for various locations within the three large, nearby galaxies NGC 3031 (M81), NGC 5194 (M51), and NGC 7331. ...

Recent results from BATSE device onboard GRO observatory have shown full isotropy of gamma-ray bursts locations upon the sky and their unhomogeneous space density ) (Meegan et al. 1992), where is the angle between the source and the galactic center, b is the galactic latitude and signifies averaging upon the whole sample. ...

T he Siding Spring Survey (SSS) is a Near-Earth Object search program that utilises the 0.5-m Uppsala Schmidt Telescope at Siding Spring Observatory, N.S.W., Australia. ... The mission of the Siding Spring Survey is to contribute to the inventory of near-earth objects (NEOs), or more specifically, the potentially hazardous asteroids (PHAs) and comets (PHOs) that may pose a threat of impact and thus harm to civilization. ...

A statistical method for the evaluation of the probable amount of interlopers included in the most recently identified asteroid families is developed. ... An application to the most important families listed by Zappal\`a \etal\ {\bf [1995, Icarus in press]} allows to derive the probable amount of interlopers at different size ranges. ... The procedure developed in this paper allows to assess ``how many'' interlopers are probably included in the nominal member lists, but not ``which ones''. ...
