The informally named feature Wright Mons, located south of Sputnik Planum on Pluto, is an unusual feature that s about 100 miles (160 kilometers) wide and 13,000 feet (4km) high. It displays a summit depression (visible in the center of the image) that's approximately 35 miles (56km) across, with a distinctive hummocky texture on its sides. The rim of the summit depression also shows concentric fracturing. ...

. Comment on J0431+2037 . A Gigahertz Peaked Spectrum (GPS) galaxy with complex radio structure on the scale of 10 to 100 mas (combined EVN+MERLIN data at 1.6 GHz, Dallacasa et al. 1995). Our image is consistent with the center-southern features of Dallacasa et al. (1995). The northern feature, ~180 mas N-NW from the field center, outside the boundary of the displayed image, can barely be seen in our data. VLBApls home page . Last modified: 16 Oct 2000
