Join Gary Fujihara’s Maunakea Skies talk about Meteoritics: the Science of Rocks from Space. The talk is in the ‘Imiloa planetarium on May 16, 2014 at 7 pm.
Fujihara, UH Institute for Astronomy, will take the audience on a brief history of man and meteorite, separating fact from myth, leading to the current model of meteoritics, or the science of rocks from space.
Meteorites are rocks that have dropped from space, surviving their fiery deliverance onto the surface of planet Earth. Unlike the rocks found on the crust of the Earth however, many of these denizens of space have remained pristine and preserved much in the state they began, accreting out of the solar nebula 4.56 billion years ago. This allows scientists to extract clues out of the stones’ mineralogical and chemical makeup, helping to establish theories on the formation and evolution of our solar system.
Most meteorites originate from the asteroid belt, a region of the solar system between the orbits of planets Mars and Jupiter, and a family of meteorites is believed to have come from a specific one, Asteroid 4 Vesta. A small minority of meteorites hail from the moon and the red planet. How do we know their origins and are there other parent bodies of meteorites? What are meteor showers and do they produce meteorites? Where are most meteorites found? Have meteorites ever hit something or someone? What kinds of meteorites are there and what do they look like? How do you know if you have found a meteorite and what you do to authenticate it? Join Fujihara as he helps to shed light on these questions.
