A R C H I V E S

This Radio-image, obtained by the NASA - Magellan Spacecraft, with radar illumination from West to East, shows 3 (three) unusually-looking Volcanoes located on the Planet Venus, in the Guinevere Planitia Lowland.

At the center of the image, is a large feature (approx. 50 Km or about 31 miles in diameter) with an unusual shape: it is, as a matter of fact, very round (when viewed from above), with Steep Slides and a Flat Top. These Volcanoes are believed to be the result of relatively thick and sticky (---> viscous) Lava Flows that originated from a single point source.

Although a faint remnant of its original Circular Shape is preserved, the Northern Rim of this aforementioned center Volcano shows a steep Scarp. The Scarp is probably the result of material that slid away from the Volcano itself and, some time afterwards, was covered by Lava Flows. This Volcano overlaps another (still Volcanic in Nature) Surface Feature - visible to the South-West - that is about 45 Km (approx. 28 miles) in diameter, and disrupted by many Fractures.

The South-Eastern Volcano (which is about 25 Km or approx. 15,5 miles in diameter) appears to be the highest of the three, since its illuminated Western Edge has the brightest radar return. The Scalloped Edges give to this Feature a bottlecap-like appearance and they are (probably) the result of multiple Land (or Volcanic Mud) slides that occurred along the Margin of the Volcano itself.

This frame has been colorized, according to an informed speculation carried out by Dr Paolo C. Fienga (LXTT-IPF), in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Magellan Spacecraft and then looked outside, towards the Surface of Venus), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
