... Generally, impact craters have a circular outline, a raised rim, and a depth that is shallow relative to the diameter. The crater is surrounded by ejecta deposits that decrease in thickness outward from the crater rim. ... The Venusian impact crater Danilova is 48 kilometers (30 miles) in diameter. ... The ejecta blanket and the circular rim of a crater are very bright in radar images because both are rough, with many facets oriented perpendicular to the radar illumination. ... Irregular craters . ...
Astronotes Armagh Planetarium's Stellar Blog! ... By admin September 21, 2012 Posted in: Armagh Planetarium . ... Reply . ... Posted September 22, 2012 at 8:18 AM . ... I saw it in armagh about 10,45 the only way that I could describe instead of a firework going up into the sky and exploding it came down from the sky I actually thought it was someone letting off fire works but it lingered around too long for it to be a firework and amongst all of this I seen several shooting stars a great clear night! ...
... Oke (AJ, 99, 1621, 1990) has provided absolute spectral energy distributions covering the wavelength range 3200 to 9200A in AB magnitudes for 25 stars. ... The reduced magnitudes are tabulated at 1A intervals from 3300 to 4700A and at 2A intervals from 4700 to 9200A. Comparison of the fluxes with those determined elsewhere showed that Oke's absolute magnitudes are systematically brighter by 0.04 mag. The magnitudes and fluxes plotted have been corrected for this effect. ...

This could be considered an underestimate, because QSOs are easier to identify than early-type galaxies which appear to dominate the red sample so the 14 objects with unidentified spectra are most likely to be galaxies.) ...
