The surface of Venus is wasted with strange, almost circular properties called coronae. Unlike anything that is seen on Earth today, they can stretch hundreds of miles in diameter, even to cross a thousand signs. Or they can only be a dozen miles across. In the images taken from orbit, they look like chaotic scribes engraved into a rock surrounding the partially collapsed center.
Large or small, their origin has long been a mystery to planets scientists. This is especially mysterious because Venus is the above -ground world, similar to the Earth, that it is considered the “twin” of our planet, almost the same size and density. We are also neighbors, placing both worlds at similar distances. So why is there no coronation in Venus, but there is no land?
A new study published in the magazine Publications of the National Academy of Sciences Offers an intriguing explanation – and this could give us a great influence on how Venus and Earth roads were different. Today, volcanoes prevail for more than 860 degrees Fahrenheit; The other is the world of the temperate ocean that covers life.
“We have this solar system size laboratory,” says Madeleine Kerr, author of the San Deigo San Deigo Sharippps Institute of Oceanography. “We have a front row seat to see why these planets are so different.”
The geography of Venus and Earth is fundamentally different in one main manner: Venus surface is made of one giant crust, and the Earth is a puzzle for moving tectonic plates that are pumped into the mantle and recycled above the EONS. But that was not always the case. The Earth also started as one uninterrupted shell, and scientists still disagree when it first split into tectonic plates.
In a sense, Venus, who has never grown from this phase, offers a window into the history of the Earth. Previous studies, using NASA Magellan’s mission data, suggested that the planet was not as geologically “dead” as it once believed, and that Coranae could be proof of constant tectonic activities.
One leading theory of corona formation indicates that they are made by a hot material stain from Venus mantle bubbles to the surface and pushes to the bottom of the crust.
In this latest study, researchers are based on this idea, forming the planet’s mantle convection, modeling how these magma explosions drive thousands of miles from the core. Their conclusions to the theory added that these hot spots go to the “glass ceiling” about 400 miles under the surface, where the mantle -changing crystal structure blocks the rising material. So, instead of one huge stain, a grape of smaller stains, pulling to the surface, creating a strange shape of a coron. It could also explain why they are very different.
There is still a lot to do to check this bustle, but the researchers believe they are on the brink of breakthrough, similar to how the theory of record tectonics has changed our understanding of Earth’s history not so distant past.
“The current state of cognition of Venus planet is analogous to the seventh seventh preschool era because we are currently lacking in equivalent unifying theories that can associate how heat transfer from the planet’s interior manifests itself in tectones and magmatic properties observed on Venus on the surface of Venus.” “With this new explanation of Venus surface features, we think the revolution has begun and even more interesting discoveries are right next to.”
