\n WASHINGTON \u2013 Scientists have identified 37 volcanic structures on Venus that app<\/a>ear to be recently active \u2013 and probably still are today \u2013 painting the picture of a geologically dynamic planet and not a dormant world as long thought.<\/p>\n

The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet\u2019s interior and provided compelling evidence of widespread recent tectonic and magma activity on Venus\u2019s surface, researchers said on Monday.<\/p>\n

Many scientists long had thought Venus, lacking the plate tectonics that gradually reshape Earth\u2019s surface, was essentially dormant geologically for the past half billion years.<\/p>\n

\u201cOur work shows that some of that interior heat is still able to reach the surface even today. Venus is clearly not so geologically dead or dormant as previously thought,\u201d said Earth and planetary scientist Anna G\u00fclcher of the Institute of Geophysics in Zurich, lead author of the research published in the journal Nature Geoscience<\/a>.<\/p>\n

The researchers determined the type of geological features that could exist only in a recently active corona \u2013 a telltale trench surrounding the structure. Then they scoured radar images of Venus from NASA\u2019s Magellan spacecraft in the 1990s to find coronae that fit the bill. Of 133 coronae examined, 37 appear to have been active in the past 2 million to 3 million years, a blink of the eye in geological time.<\/p>\n

\u201cIn my opinion, many of these structures are indeed active today,\u201d said University of Maryland geophysicist and study co-author Laurent Montesi.<\/p>\n

Coronae are essentially fields of lava flows and major faults spanning a large circular area. Many of the 37 reside within in a gigantic ring in the planet\u2019s Southern Hemisphere, including a colossal corona called Artemis 1,300 miles in diameter.<\/p>\n

Venus, Earth\u2019s closest and just slightly smaller planetary neighbor, is covered by clouds of sulfuric acid and has surface temperatures hot enough to melt lead.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
