The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus. Within the Solar System, it is the one nearest to Earth and most like it in terms of mass, but has no magnetic field or recognizable plate tectonic system.
Only four spacecraft have ever returned images from Venus’ surface. The world next door doesn’t make it easy, with searing heat and crushing pressure that quickly destroy any lander. In 1975 and 1982, four of the Soviet Union’s Venera probes captured our only images of Venus’ surface.
If we could slice Venus and Earth in half, pole to pole, and place them side by side, they would look remarkably similar. Each planet has an iron core enveloped by a hot-rock mantle; the thinnest of skins forms a rocky, exterior crust.
The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms.
Feb 9, 2022 · In December 2021, researchers published new findings about the rediscovery of the comet-like tail of plasma streaming out behind Venus, called a “tail ray”. The new results showed this tail of particles extending nearly 5,000 miles out from the Venusian atmosphere.
Dec 29, 2023 · It consists of an orbiter and an atmospheric descent probe, and will take high-resolution images of Venus’ surface, particularly focusing on features called tesserae — strange, wrinkled landforms that we do not fully understand.
