There are over 80,000 [2] volcanoes on Venus detected through radar mapping. For many years scientists debated on whether Venus was currently active or if the volcanic structures were remnants from the past. There are few impact craters on Venus' surface which pointed to relatively recent resurfacing. [3]
Maat Mons is the second-highest mountain on Venus, and is a recently active shield volcano. Over 1,100 volcanic structures over 20 km in diameter have been identified on Venus, and it is assumed that smaller structures probably number many times these. These structures include large volcanic edifices, shield volcano fields, and individual calderas.
Although Venus is superficially similar to Earth, it seems that the tectonic plates so active in Earth's geology do not exist on Venus. About 80% of the planet consists of a mosaic of volcanic lava plains, dotted with more than a hundred large isolated shield volcanoes , and many hundreds of smaller volcanoes and volcanic constructs such as ...
Venus appears to be more volcanically active than previously known, according to scientists whose new analysis of decades-old radar images has spotted evidence of eruptions at two additional sites ...
Surface of the planet is changing in ways that suggest it has volcanic eruptions and lava flows
On Venus, volcanic features are very numerous and quite diverse, but, like on Mars, none are known to be currently active. These volcanoes range from several to several hundred kilometers in diameter; a majority of them are shield volcanoes. In addition, Venus has unusual types of volcanoes: pancake domes and scalloped margin domes. Most small ...
The simple answer is volcanoes, NASA says. ... massive amounts of material may have helped transform Venus from a temperate and wet world to the acidic hothouse it is today,” NASA said in a news ...
It is sometimes called Earth's "sister planet" due to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity.
