scientist have get it on for a while now that there were once massive volcanic bang on the surface of Venus , specifically in the region known as the Ganiki Chasma . But now they trust some of the planet ’s volcano are still spewing red-hot magma there .
" We knew that Ganiki Chasma was the result of volcanism that had occurred clean late in geologic terms , but we did n’t know if it formed yesterday or was a billion yr old,“saidJames Head , the Colorado - generator of a new outside study , out recently inGeophysical Research Letters , that comb out through the data from the European Space Agency’sVenus Expressmission .
" We have now learn several events where a bit on the open suddenly have much hotter , and then cool down down again , " Eugene Shalygin , lead author of the study , aver .
And he meansa lothotter . Venus is typically a scorching 896 degrees Fahrenheit . Over the row of the cogitation , at least one spot observed by the Venus Express peaked at a temperature of 1526 degrees Fahrenheit . The scientists believe that these temperature spikes , which were contained to four specific areas and hold up just a few days , are the consequence of hot magma roil up to the surface from inside the planet — in other words , active volcanic eruptions . These findings are consistent with early research that detected transient spikes in S dioxide in Venus ’ upper atmosphere , which is another likely signaling of active volcanism .
The volcanoes place Venus amongst a minor class within our solar system . In add-on to Earth , the only other known base to magma - chuck vent is Jupiter ’s moon Io . Uranus ' moon Triton and Saturn ’s moon Enceladus both contain cryovolcanos , which regorge icy gases .
" This discovery fit nicely with the emerging motion-picture show of very late bodily process in Venus ’ geological history , " Head said . " These noteworthy findings were the answer of collaborations spanning many years and many political borders . They emphasise the grandness of international coaction in exploring our solar system and sympathize how it evolves . "
