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. ... Based on the CSS Mission page . ... Siding Spring Survey Main Page . ...

... Scientific Objectives of CLASH: . By observing 25 massive galaxy clusters with HST's panchromatic imaging capabilities (Wide-field Camera 3, WFC3, and the Advanced Camera for Surveys, ACS), CLASH accomplishes its four primary science goals: . ... The CLASH program has observed these 25 clusters over a 2.7 year period (Nov 2010 - July 2013). ... The CLASH program observed the clusters with the Advanced Camera for Surveys (ACS) and both the UVIS and IR channels of the Wide-Field Camera 3 (WFC3). ...

... The ChaMPlane survey is being conducted at the Harvard-Smithsonian Center for Astrophysics. The ChaMPlane team is conducting a "Bulge Latitude Survey" (BLS) to measure the latitude distribution of faint X-ray point sources in the region b = +/- 1.5њ, l = +/- 0.35њ centered at l = 0њ. ... In Chandra cycle 7, two-thirds of the region below the galactic plane were observed (BLS-Sa); observations of a similar-sized region above the plane (BLS-Na) are planned for cycle 8 (summer 2007). ...

The Extragalactic ALFA Zone of Avoidance team is mapping the distribution of low-Galactic-latitude galaxies and large scale structures through detection of galaxies' 21-cm emission with ALFA. This Zone of Avoidance (ZOA) survey finds new HI galaxies which lie hidden behind the Milky Way, and also provides redshifts and other HI parameters for partially-obscured galaxies known at other wavelengths. ... Discovery and Follow-up of a Nearby Galaxy from the Arecibo Zone of Avoidance Survey. ...

... We illustrate in Fig. 5a the sky distribution of all our observed ELGs (filled circles) in comparison with the distribution of all other observed ELGs in the same zone (open circles). ... The redshift distribution of our ELGs is shown in Fig. 5b (solid line) in comparison with the same distribution for all other Case ELG in this zone (dashed line). ... This redshift distribution looks very similar to that of BCGs in the zone of the SBS (Pustilnik et al. [ 1995 ]). root . ...
