Venus could be volcanically active today, study

Venus is generally considered the "sister planet" of the earth, but that association is only based on its size and density.

UniverseToday describes the planet's hazy and dense atmosphere underneath.

Filibert added: "For example, we could study how planets cool and why the Earth and Venus have active volcanism, but Mars does not".

"Then we can better monitor changes on Venus."

Figure above shows the volcanic peak Idunn Mons in the Imdr Regio area of Venus. The colored overlay shows the heat patterns derived from surface brightness data collected by the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) aboard ESA's Venus Express spacecraft.

For the study's lead author Justin Filiberto, studying Venus' active volcanism can shed new light on the conditions of other planets.

If the discovery is confirmed, scientists believe Venus will be a "great place" for future missions to visit.

According to the Magellan spacecraft back in 1990, they spotted that planet. At the time, scientists were unable to determine the exact ages of the lava flows because of the unknowns about how volcanic rocks change in response to Venus' atmosphere, which is high in carbon dioxide and sulfur. This suggests that there are active volcanoes on Venus that create new lava flows that are free of magnetite and hematite.

The team reportedly recreated Venus' hot atmosphere in their lab to study how Venusian minerals react and change over time. Scientists reviewed data from the European Space Agency's Venus Express probe, suggesting that some of the lava flows is as recent as 2.5 million years old, and potentially less than 2,50,000 years old.

Additionally, they discovered that the close to-infrared signature emitted by these minerals (that are in keeping with the information obtained by the Venus Specific mission) would disappear inside days.

It's known that volcanoes existed on the moon and Mars alike, but they are long dormant on both celestial bodies.

We won't be able to fact-check the findings until we send a new craft to Venus. ISRO aims to explore in its Venus mission include surface, subsurface, and atmosphere of the planet, as well as its interaction with the Sun. These include India's Shukrayaan-1 orbiter and Russia's Venera-D spacecraft, which are now in development and scheduled to launch by 2023 and 2026, respectively. Read the original article.
