1Influence of Planets on the SunExtraSolar Planets
Shows the movement of the sun due to the gravitational pull of the planets. The contribution from each planet can be isolated by toggling checkboxes

2Radial Velocity Graph
Shows a star and planet in orbit around each other while tracing out the star's radial velocity curve
http://astro.unl.edu/classaction/ani...nets_graph.swf
3Transit Simulator-NAAP
Demonstrates how a planet passing in front of its parent star can cause dips in the star's lightcurve, potentially leading to the planet's detection

4Extrasolar Planet Radial Velocity Demonstrator
Demonstrates how the spectrum of a star is shifted as it and its planet orbit their common center of mass
http://astro.unl.edu/classaction/ani...locitydemo.swf
5Radial Velocity Simulator -NAAP
Models the motion of an extrasolar planet and its star around their common center of mass, and the effect this motion has on the star's observed radial velocity
http://astro.unl.edu/classaction/ani...ysimulator.swf
6Doppler Shift Demonstrator
Shows circular waves expanding from a source. Movement of the source or observer affects the frequency of the waves seen by the observer, demonstrating doppler shift

7Pulsar Period Simulator
Demonstrates how the movement of a pulsar and planet around their common center of mass affects the timing of pulse arrivals

8Hammer Thrower Comparison
Illustrates how the movement of a star and its planet about their center of mass compares to a hammer thrower swinging a heavy metal ball

Solar System Debris
Driving Through Snow
Shows a snow shower from the perspective of a car driving through it, demonstrating how the snow seems to diverge from some central point (the radiant). Provides an analogy to a meteor shower

Sidereal Time and Hour Angle Demonstrator200level
Shows how sidereal time and the hour angle of a star are related

Hi, Dear astronomers
This video is about Raining Loops on the Sun
On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and a dazzling magnetic display known as coronal rain. Hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, and outlining the fields as it slowly falls back to the solar surface
