Simulations of the Breakup of Comet Shoemaker-Levy 9 Employing a Swarm Model: Initial Conditions
The breakup of comet Shoemaker-Levy 9 due to its gravitational interaction with Jupiter in July, 1994 is simulated using a swarm model. In this simulation, the comet is modeled as an initially spherical distribution of 16,384 particles. The particles interact with the tidal field of Jupiter and with each other through inter-particle gravitation and collisions. All simulations were performed on the Maspar MP-2 at NASA-GSFC.
Great Zoom into Houston, Texas: Reliant Stadium (with spin)
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl

This video also reflects on the difficulties posed by the mountains. Essentially a travel video with some historic details (Running Time 5:05).
Ten Ways the World Will End: The Big Freeze
This video shows how the next Ice Age could start and its impact on the Earth. Very well done with excellent graphics. A good way to explore the impact of global warming. Not for younger students. Shows impact of freezing on humans, too.
Galileo on the Moon
Galileo used thought experiments to test many assumptions, including the notion that heavy objects fall more quickly than lighter objects when they are dropped. Lacking access to either a vacuum chamber or a planetary body that has no atmosphere, he nevertheless correctly predicted that all falling objects would accelerate at the same rate in the absence of air resistance. In this video segment from NASA, astronaut David Scott demonstrates the correctness of Galileo's prediction. Run time 0:47.
Galileo: Sun-Centered System
Before the 17th century, people generally believed that Earth was at the center of the universe. Galileo, however, was not afraid to challenge existing beliefs when he published his work in support of the Sun-centered, or heliocentric, Copernican theory. In this video segment adapted from NOVA, learn about the two opposing worldviews and the strong piece of evidence Galileo offered to support the heliocentric theory. Closed captioning included. Run time 05:06.
Galileo used his telescope to gather data about the heavens, and his observations and theories sparked much controversy. Contrary to the popular belief of the time, Galileo suggested that Earth was not the center of the universe. In this video segment adapted from NOVA, the importance of unbiased scientific inquiry is demonstrated by Galileo's observations of sunspots. Closed captioning included. Run time 03:42.
Leonardo Da Vinci -The Man Who Knew Everything
