A NASA supercomputer sparks a new hypothesis about the formation of the Moon

The Moon was formed billions of years ago when a Mars-sized object (called Theia) collided with Earth. NASA indicates on its blog that this collision is “a scientific puzzle that researchers have studied for decades, without a conclusive answer.”

Most theories state that the Moon formed from the debris of the collision, which accumulated in orbit over months or years. However, a new simulation indicates that The satellite could have been built in a few hoursWhen material from Earth and Theia was launched directly into orbit upon impact.

Jacob Kageres (postdoctoral researcher at the NASA Ames Research Center) has published a paper in The Astrophysical Journal Letters that “opens up a whole new series of Possible starting point for Moon’s evolution, We didn’t know what the results of these high-resolution simulations would be, so it was exciting that the results could include a fascinating Moon-like satellite in orbit.

The research simulations run at the highest resolution of any simulations run to study the origins of the Moon, plus it adds additional computational power. Allows scientists to see how new behaviors emerge In a way that previous studies could not see.

there are different theories

Understanding the Moon’s origin requires using knowledge of its mass, orbit, and lunar rock analysis to develop theories based on its isotopic signature (that is, how and where an object was formed). The lunar samples used by scientists are similar to rocks on Earth, therefore, it causes Most of the material that makes up the Moon comes from our planet.,

about the theory of theia and earth, supposedly Space object sprayed into orbit and mixed with some material from Earth to form the Moon, especially its outer layers, which may help explain this compositional similarity.

On the other hand, NASA states on its blog that further research has been proposed to “explain these structural similarities, such as the synesthesia model, where Collision creates moon inside a whirlpool of vaporized rock, This formation theory provides a cleaner and more elegant explanation, and may provide new ways to find answers to other unsolved mysteries.”

The space agency further states that “confirming which of these theories is correct will require analysis of future lunar samples brought back to Earth for study by NASA’s upcoming Artemis missions. As scientists explore the Moon.” gain access to samples from elsewhere and deeper beneath the surface, they will be able to Compare how the real-world data matches up with these simulated scenarios,

Vincent Acke (Durham University researcher) concludes for the blog that “the more we learn about how the Moon formed, the more we discover about the evolution of our Earth. their stories are intertwinedand may repeat themselves in the history of other planets combined by similar or very different collisions.”
