Oriented Meteorites: Nature’s Sculpture by Fire

Location: Slichter 3853
Time: 2:30PM

Meteorites enter the Earth’s atmosphere at speeds near 40,000 mph. These extreme velocities compress the air into a luminous hot plasma which envelopes them like a sheath. Most meteorites tumble during their fall; fragmentation is common. However a few exceptional ones maintain a stable orientation with one side continually facing forward (like space capsules). These oriented meteorites are sculpted into patterns of great beauty. Nick Gessler will discuss the physics and aesthetics of these rare rocks from space and focus on the newest addition to the UCLA Meteorite Gallery: a unique world-class oriented meteorite found near Baker, California.

The asteroid-meteorite connection

Location: Slichter 3853
Time: 2:30PM

Meteorites come from the Asteroid Belt, a part of the Solar System mainly between 2.2 and 3.4 AU, intermediate between the orbits of Mars and Jupiter. Meteorites are well characterized by laboratory studies. The properties of asteroids are mainly obtained from astronomical observations in the visible and infrared. From these we can infer where certain meteorite classes originated.
