Great Pyramid May Contain An ‘Iron Throne’ Made Of Meteorites, Says New Theory

Via Inquistir.com Archaeoastronomy professor thinks pharoahs used the throne to travel to the afterlife The Great Pyramid of Giza is one of the wonders of the world and is a magnificent feat of ancient architecture. But an Italian professor of archaeoastronomy thinks that it contains something that makes it even more amazing. He believes that the void at the center […]

Three times further away from the sun than the Earth lies an enormous lump of metal. Around 252km in diameter, the metallic “M-class” asteroid 16 Psyche is the target of NASA’s next mission to the belt of giant rocks that encircles the inner solar system. And the space agency now plans to visit it much sooner than originally planned.

Not only has the launch has been brought forward one year to the summer of 2022, but NASA’s scientists have also found a way to get to Psyche (pronounced SYKe-ee) much faster by taking a more efficient trajectory. The new route means the Psyche spacecraft won’t have to swing around the Earth to build up speed and won’t pass as close to the sun, so it needs less heat protection. It is now due to arrive in 2026, four years earlier than the original timeline.

The main aim of the journey to Psyshe is to gather more information about our own solar system. Psyche is one of many wandering members of the asteroid belt. Unlike the rest of its rocky neighbours, Psyche appears to be entirely made of nickel and iron, just like the Earth’s core. This, together with its size, has led to the theory that it might be the remains of the inside of a planet.

Asteroids are made up of primitive materials, leftovers from the dust cloud from which our solar system originated. Different types of asteroids resemble the various steps it took to form planets from this dust cloud. This means they reveal a lot about the origin and evolution of our solar system. Scientists think Psyche could be what’s left of an exposed metal core of a planet very similar to Earth.

Metal asteroid Psyche is all set for an early visit from NASA

There are other reasons for visiting asteroids. For one thing, possible collisions with Earth can have devastating effects. The impact of an 15km-wide asteroid approximately 65m years ago is linked to the extinction of the dinosaurs. And the explosion of the 30m-diameter Chelyabinsk asteroid over Russia in 2013 led to injuries and damage on the ground. We need to know as much as possible about the composition and physical make-up of asteroids to devise the best ways to defend our planet.

Cosmic Lessons – Madagascar Chevrons and Megatsunamis – Part 4

Picking up the story where I left off in the last installment: I presented information on the discovery of an inscribed, disk-shaped stone found by Sir Austen Henry Layard while excavating the ruins of the royal palace at Ninevah back in the 1850s. This stone, often referred to as the Planisphere, had cuneiform pictographic markings on it that two research […]
