Advanced Igneous Petrology covers the history of and recent developments in the study of igneous rocks. Students review the chemistry and structure of igneous rock-forming minerals and proceed to study how these minerals occur and interact in igneous rocks. The course focuses on igneous processes and how we have learned about them through studying a number of significant sites worldwide.

In this year's seminar, we will embark on a scientific journey through some of the most controversial topics about the origin and formation of our home planet. This journey will take us to other planetary bodies - even to other solar systems - as we immerse ourselves in observations and theories from the microscopic to the universe scale.
The seminar will be organized around three broad questions: How was the Earth formed? What did early Earth look like? When did living organisms first appear on Earth?
Experts in meteorites, geology of other planets, thermodynamics and tracers of living organisms, and theories of formation and evolution of planets, including early atmosphere and oceans, will come to WHOI and help us address these questions.

This 24 minute planetarium show teaches about meteors, meteorites, asteroids, and comets. The show was created for fulldome theaters, but is also available on DVD to be shown in flat version for TVs and computer monitors, and can be freely viewed online. It shows the effects of the Chixulub and Tungusta events, plus the Pallasite impact that resulted in the Brenham meteorite fall, and describes ways that asteroid hunters seek new objects in the solar system, and how ground penetrating radar is used to find meteorites that have survived to the Earth's surface. Narrated by astronaut Tom Jones, it also discusses ways that humans might try to deflect an asteroid or comet that is on a collision course with Earth. The show was created for informal science venues (digital planetariums); it is also useful as supplemental material for middle school science. Impact Earth is available for free if presented directly from the Space Update site (widescreen or fisheye views linked from YouTube). Otherwise, a DVD of the show can be purchased for $10.

Students will experimentally learn how meteoroids are formed. They will melt a comet, learning about its composition, and break apart asteroids. The students learn the differences between meteoroids, meteors and meteorites and how the impact of asteroids/meteoroids can affect life on Earth.

This is an introduction to the study of the solar system with emphasis on the latest spacecraft results. The subject covers basic principles rather than detailed mathematical and physical models. Topics include: an overview of the solar system, planetary orbits, rings, planetary formation, meteorites, asteroids, comets, planetary surfaces and cratering, planetary interiors, planetary atmospheres, and life in the solar system.

This is a 30 minute lesson where students will be able to:
1. Describe the size, composition, and motion of meteors and comets.
2. Discuss the similarities and differences in comets and meteors.
3. Explain:
a. what happens to meteors as they fall through the atmosphere
b. why comet debris is observed as a meteor shower from the Earth
c. how the planet's gravitational forces affect a comet's orbit.
d. why we see a comet's tail.
e. why a comet disintegrates when it gets close to the sun.
