The world that we call home was, once upon a long time ago, a cold nebular cloud of gas and dust. Most of the celestial objects that are familiar to us formed and evolved from that cloud, including the sun, Earth, and the other planets in our solar system. During the solar system's formation, the gas giant Jupiter captured most of the available material to produce planets. Scientists at Caltech and elsewhere work to decipher the events leading to the formation, evolution, and current structure of Jupiter in an attempt to extract fundamental lessons of planet formation. General lessons obtained from Jupiter help us understand the formation of the increasing number of planets that we can observe orbiting stars beyond our solar system. But perhaps of even more relevance, the dominant mass of Jupiter defines the formation and the current environment of the rest of the planets in our solar system, including our own very special planet Earth. Consequently, scientists concentrate on Jupiter in an attempt to find clues to understand what makes our solar system so special. After all, our solar system remains the only planetary system where we have observed life as we know it. In this presentation, Idini will travel to the center of Jupiter in a journey that will take us from the visible zonal winds and the Great Red Spot to the planet's hidden, deeply settled core.

About the Speaker

Benjamin Idini is a PhD candidate in planetary geophysics at Caltech, where he studies the core of Jupiter by exploiting the gravitational field of tides recorded by NASA's Juno mission. As a geophysicist, Idini extends his expertise about how our planet works to understand other planets in the solar system.

Idini grew up in remote Chiloé, an island off the coast of Patagonia in southern Chile. After college, he joined Caltech in 2017 to study geophysics and planetary science. Idini began collaborating with the Juno science team in late 2019. In addition to the core of Jupiter, he also studies the mechanics of earthquakes from numerical simulations and satellite radar observations of Earth's surface deformation.

Beyond his research, Idini works to further science communication in Spanish and free access to high-quality public education in his home country of Chile. He loves hiking in the San Gabriel Mountains and driving up the Owens Valley to practice snowboarding in Mammoth Lakes during the winter season. When not involved in outdoor recreation, he spends his spare time reading Russian and Latin American literature.
