New study questions old theories about ‘sister earth’

UNITED STATES (OBSERVATORY NEWS) — Scientists believed that Venus once had a climate that makes it as livable as Earth’s, but a new study found results to the contrary.

The recent study found that the heights on the second planet in the solar system in terms of proximity to the sun, was not flowing with water, but molten lava.

A team of scientists from the US-based Lunar and Planetary Institute, by analyzing radar data to redraw a map of Ovda Regio on Venus, determined that what was initially thought to be granite rocks was actually basalt. Black hard igneous rocks, which consist of rapid cooling of lava.

The team re-examined the highest Ovda Regio plateau on Venus and found it to be composed of basaltic rocks, contradicting earlier theories that Venus might be the Earth’s counterpart by containing an ancient ocean of liquid water.

The new findings have raised scientists’ suspicions of earlier Earth-like theories millions of years ago, because basaltic rocks can form with or without water.

“We know very little about the surface of Venus,” said Dr. Alan Treman, co-author of the study from the Lunar and Planetary Institute. “If Ovda Regio is made up of basalt rocks like most Venus, it is likely to have peaked.” Current by internal forces, probably like mountains produced by tectonic plates on Earth.”

The findings could change all previous experts’ beliefs about Venus that the planet contained mild weather and was capable of harboring liquid water before turning into “hell” some 700 million years ago.
