“The Venus Zone” –Second Rock from Sun Once Habitable and Radically Different from Today

Venus from the ISS

 

“Our models show that there is a real possibility that Venus could have been habitable and radically different from the Venus we see today,” said Michael Way of The Goddard Institute for Space Science about Earth’s ‘twisted sister’ planet. “This opens up all kinds of implications for exoplanets found in what is called the ‘Venus Zone’, which may in fact host liquid water and temperate climates.”

“The Lost Story” –Continent-Sized ‘Fossils’ of Ancient Earth

Earth from Moon Apollo 12

 

Scientists long theorized that separated continents deep in Earth’s mantle came from subducted oceanic plates. But the new study indicates these distinct regions may have been formed from an ancient magma ocean that solidified during the beginning of Earth’s formation and may have survived the massive Moon-creating impact. These ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth’s crust, offering a window into the building blocks of our planet.

“What Lies Below” — Unknown Ancient Jurassic World of 100 Volcanoes Discovered

Permian Volcanoes

 

“While the majority of Earth’s volcanic activity occurs at the boundaries of tectonic plates, or under the Earth’s oceans, this ancient Jurassic world developed deep within the interior of the Australian continent,” says co-author  Simon Holford, from the University of Adelaide’s Australian School of Petroleum. “Its discovery raises the prospect that more undiscovered volcanic worlds reside beneath the poorly explored surface of Australia.”

“Spectacular” –NASA Captures Earth Exploding ‘After 100-Year Sleep’

Raikoke Volcano

 

A dramatic photo released by NASA shows the volcano’s plume shooting up over clouds above Raikoke, an uninhabited volcanic island in the northwest Pacific, that last erupted in 1924 and 1778. It then went silent for nearly 100 years, until, on June 22, Raikoke spewed a blast of ash and volcanic glass so powerful it could be seen from the International Space Station.

Mars Message in a Bottle –“Earth’s Future”

Mars 2020 Landing Site Jezero Crater

 

A series of missions will set a new bar for humankind’s technological achievements as NASA and ESA aim to bring  samples back from Mars Jezero Crater that once held a lake and contains an ancient preserved river delta. The rocks in the area will have preserved information about the Red Planet’s long and diverse geologic history and its stark, dramatic climate change through the eons.

“Deep Life” — Scientists Identify a Signal That Survived the Fiery Evolution of Early Earth

Blue Whale

 

“The evolution of the planet and the life on it are intertwined. We can’t understand one without understanding the other,” says Caltech assistant professor of geology Claire Bucholz about a new study that provides fresh evidence for just how deep—literally—the strong connection is between the geology of Earth and the ocean life that flourishes on it.
