solar system

The solar system consists of the Sun, Jupiter, Saturn, and a small additional amount of debris which formed all of the other planets, moons, comets, asteroids, etc.

How did the Sun - whose core is extremely hot and dense - form from a cold dilute cloud of gas and dust? What are the vital roles that small amounts of dust play in making life possible in our solar system? Obviously dust is necessary to form rocky planets like Earth as well as the molecules and structures of living things, but dust also affects the lifespan of the Sun.

How is it possible for a giant gas planet like Jupiter to form from the remaining gas and dust beyond the Sun? Was there enough time for Jupiter to form before the Sun ejected the remaining gases from the solar system?


Solar System

The five billion year history of the solar system involves the formation and evolution of the Sun, planets, moons, planetesimals, asteroids, comets, and interplanetary gas and dust. Transformations of energy and matter in the interior of the Sun and planets involve gravitational, electromagnetic and nuclear forces. Heat transport may involve thermal conduction, convection, and radiation. A logarithmic timeline best depicts this domain. NASA image published by

The Sun submenu is a work in progress that will eventually contain slides from ASTR 301 lectures and/or one chapter of an unpublished reference book.

Watch all of these animated gifs from beginning to end

The Jupiter subdirectory contains the slides from an ASTR 301 guest lecture including lecture notes. As a preview, the subdirectory also displays an animated low color resolution gif that runs about four minutes - five seconds for each of the 48 slides.
Venus is often called Earth's twin. Venus has many similarities to Earth, but also many differences. The following animated gif can be downloaded for slower playback. It highlights some of the mysteries hidden below the clouds of Venus.
