Planetary science, also known as planetology and closely related to planetary astronomy, is the Science of Planets or Planetary systems The California Institute of Technology (commonly referred to as Caltech) is a private, Coeducational research university located in Pasadena Originally from New Zealand, he received his Ph. New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island D. from Cornell University in physics, where he proposed a model for the interior of Jupiter. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. He is well-known for applying fluid mechanics and magnetohydrodynamics to understand the internal structure and evolution of planets and moons. Fluid mechanics is the study of how Fluids move and the Forces on them Magnetohydrodynamics (MHD ( magnetofluiddynamics or hydromagnetics) is the Academic discipline which studies the dynamics of electrically A planet, as defined by the International Astronomical Union (IAU is a celestial body Orbiting a Star or stellar remnant that is A natural satellite or moon is a Celestial body that Orbits a Planet or smaller body which is called the primary. In 1984, he received the H. C. Urey Prize awarded by the Division for Planetary Sciences of the American Astronomical Society.

Sending a probe into the Earth
Stevenson's tongue-in-cheek idea about sending a probe into the earth includes the use of nuclear weapons to crack the Earth's crust, simultaneously melting and filling the crack with molten iron containing a probe. A nuclear weapon is an explosive device that derives its destructive force from Nuclear reactions either fission or a combination of fission and fusion. In Geology, a crust is the outermost solid shell of a planet or moon The iron, by the action of its weight, will propagate a crack into the mantle and would subsequently sink and reach the Earth's core in weeks. Communication with the probe would be achieved with modulated acoustic waves. [1][2]
