Volcanoes on Venus?

New evidence suggests that a volcanic peak on Venus that is more than a mile tall is still active. It could be shedding light on contentious results that claim life on the terrible planet exists.

More volcanoes exist on Venus than on any other planet in our solar system. According to previous studies, Venus has more than 1,600 big volcanoes and possibly more than 100,000 or even 1 million lesser volcanoes.

However, it has been widely argued if any are still operational today, due to the planet’s tremendous surface pressure and temperatures, which make surface probes impossible to operate for lengthy periods. And, if they last on Venus, dense sulfuric acid clouds prevent space-based examination of the planet’s surface.

Researchers looked at Idunn Mons, a Venusian volcanic peak about 1.5 miles (2.5 kilometers) high and 125 miles (200 kilometers) wide in Imdr Regio, for a new study. In the southern hemisphere of Venus, there is a volcano-rich highlands region. They also discovered what they believe to be recent activity.

The First Findings

According to previous studies, the planet has fewer craters from cosmic impacts than one might predict given the number of craters that pockmark other rocky planets in the solar system. A discovery that shows lava from active volcanoes may continue to clean the planet’s surface.

Greater knowledge of Venus’ volcanic activity could throw light on the recent discovery of phosphine gas on the planet. Some academics have speculated that this could be linked to life on the terrible planet.

Venus Express and NASA’s Magellan spacecraft took photographs of the Venusian surface that proved the presence of fresh lava flows at Idunn Mons. Winds in the lower atmosphere over Imdr Regio are also slower than expected, according to Venus Express data. The heat from recent or ongoing lava flows, according to the researchers in this new study, could be a factor.

The researchers also demonstrated that recent laboratory studies suggested that the surface rock on Venus may change chemically considerably faster than previously anticipated. Previous studies concluded that the volcanic flows atop Idunn Mons were 2.5 million years old at best. The new chemical tests reveal that these rocks were significantly younger than 250,000 years old.

All in all, the researchers concluded that Idunn Mons was recently active — possibly anywhere from 10,000 years ago to just a few years ago.

“For the first time we have combined so many and different data sets to suggest a combination of both recent and potentially ongoing eruptions. The suggestions also include the recent tectonic activity, on a terrestrial planet other than Earth,” D’Incecco said.

Several prospective missions, notably NASA’s VERITAS orbiter and the European Space Agency‘s EnVision probe, are intended to map Venus. “Future missions should prioritize these geologically young provinces for maximum effort studies to discover which could be active” if Venus is volcanically active. According to co-author Justin Filiberto, a planetary scientist at NASA’s Johnson Space Center in Florida, this is being investigated.
