New evidence hints at volcanic activity within Venuses’ Idunn Mons
An international team of researchers has found evidence that suggests possible volcanic activity involving Venuses’ Idunn Mons. In their paper published in The Planetary Science Journal, the group describes the evidence they found, but also note that their theories cannot be confirmed until new spacecraft are sent to Venus.
The researchers began with data from the Venus Express orbiter, which circled the planet from 2006 to 2014. It showed what looked like lava flows around Idunn Mons. The researchers noted that recent work by another team showed that lava on the surface of Venus would degrade faster than previously thought—so fast that any lava on the surface would have originated within the past 1,000 years. They also found that winds around Idunn Mons were being disrupted, possibly due to heat emanating from the volcano, suggesting it is still active. The researchers also note that there have been thus far unexplainable signals coming from Idunn Mons, which, they suggest, could very well be due to volcanic activity.
The researchers acknowledge that all of their evidence is circumstantial, which means that they have not found direct evidence of volcanic activity on Venus. But they also point out that there are two planned missions that involve sending probes to Venus in the near future—VERITAS and DAVINCI+—either of which could send back data that might confirm what they have suspected all along—that Venus is rife with volcanic activity. If such a finding is made, it might also explain how Venus lost its oceans and became so inhospitable.
