Signs of hypothetical fauna of Venus
On March 1 and 5, 1982, experiments in television photography instrumented by the landers VENERA-13 and -14, yielded 37 panoramas (or their fragments) of the Venus surface at the landing site. Over the past 31 years, no similar missions have been sent to Venus. Using a modern technique the VENERA panoramas were re-examined. A new analysis of Venusian surface panoramasâ details has been made. A few relatively large objects of hypothetical fauna of Venus were found with size ranging from a decimeter to half meter and with unusual morphology. Treated once again VENERA-14 panoramic images revealed âamisadaâ object about 15 cm in size possessing apparent terramorphic features. The amisadaâs body stands out with its lizard-like shape against the stone plates close by. The amisada can be included into the list of the most significant findings of the hypothetical Venusian fauna. The amisadaâs body show slow movements, which is another evidence of the Venusian faunaâs very slow style of activity, which appears to be associated with its energy constraints or, and that is more likely, with the properties of its internal medium. The terramorphic features of the Venusian fauna, if they are confirmed, may point out at outstandingly important and yet undiscovered general laws of the animated nature on different planets
Hypothetical Plants of Venus and Objects of Unidentified Nature: Life on Venus
The results of a series of Soviet VENERA missions are the only existing direct observations of Venus' surface. Recently, a series of studies was devoted to strange entities in re-processed images that were returned from the surface of the planet Venus by the VENERA landers, 33 and 40 years ago. Experiments in television photography instrumented by the landers VENERA-13 and VENERA-14 (March, 1 and 5, 1982) yielded 37 panoramas (or their fragments) of the Venus surface at the landing sites. The panoramas were re-examined using modern processing techniques and revealed âstemsâ - objects possessing apparent terramorphic features of Earth-like plants. âPlantsâ or âstemsâ are thin knotty vertical trunks on the surface of Venus that have a thickness of 0.3-3 cm and are 0.2 to 0.5 m tall. On close objects, one can see that the âstemâ at the top end is provided with a large bulge, a "burgeon" or âflowerâ, with petals surrounding a bright center
History of the Discovery of Lightning on Venus and Looking for its Origin
This presentation was part of the session : Strategic PerspectivesSixth International Planetary Probe WorkshopStudies of the atmosphere of Venus identified several minor gaseous components whose origin could involve electrical discharges, which produce high pressure and temperature in the discharge stroke. Measurements made by VENERA 11, 12, 13, 14 and PIONEER-VENUS (1978-83), as well as subsequent missions, indicated electrical activity of the atmosphere of Venus, and later of other planets.
On 21 and 25 December 1978, VENERA 11, 12 detected a large number of electromagnetic pulses, from measurements by the Groza instrument during descent and on the surface of the planet. A few days later the same phenomena were detected by the OEFD instrument of the late Professor F. Scarf, on board the PIONEER-VENUS orbiter, which registered electromagnetic pulses. The periodicity of groups of pulses detected by Groza pointed to a distant source of the electromagnetic noise. The OEFD instrument registered pulses in low frequency whistler mode. No light flashes were found. Discharges inside Earth' clouds are well visible from outside. However a search for light flashes on the night side of Venus resulted in nothing. The hypothesis of possible volcanism as an origin of the lightning was proposed. A sudden enrichment of the atmosphere of the planet by SO2 was observed by the PV instruments and was tentatively connected with volcanic activity and electromagnetic noises.
Later electromagnetic pulses coming from the atmosphere of Venus were observed by instruments of the GALILEO mission (Borucki et al., 1996). The lightning of Venus is unusual. We consider its possible similarity with high altitude discharges. Taiwanese researchers discovered recently huge lightning discharges, which rise as clusters from storm clouds to the upper layers of the atmosphere (up to 100 km). In contrast to normal lightning, these sparkling streams are propagated in rarefied air, occurring in huge clusters, having a height up to 80 km. Their duration was less than one second. It is very difficult to record these discharges. The researchers have also found that four of these streams radiated radiowaves of extremely low frequency
Mercury
Mercury, the planet closest to the Sun, is different in several respects from the other three terrestrial planets. In appearance, it resembles the heavily cratered surface of the Moon, but its density is high, it has a magnetic field and magnetosphere, but no atmosphere or ionosphere. This book reviews the progress made in Mercury studies since the flybys by Mariner 10 in 1974-75, based on the continued research using the Mariner 10 archive, on observations from Earth, and on increasingly realistic models of its interior evolution
