These flash files are realy useful for educatinal purposes and Astronomy teachers and even university professors can use them. I recommend them to all teachers. There is an old Chinese proverb
A picture is worth a thousand word
we can say
A flash file is worth a thousand word
7Three Views Spectrum Demonstrator
Demonstrates how different spectra can arise from a light bulb (a thermal source) and a cold, thin gas cloud. The spectrometer shows emission, absorption, or continuous spectra based on where the draggable telescope is pointed
http://astro.unl.edu/classaction/ani...ewsspectra.swf
8Extrasolar 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
9Doppler 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
http://astro.unl.edu/classaction/ani...pplershift.swf

Telescopes and Astronomical Instruments
1Telescope Simulator
Demonstrates the properties of a telescope, and how these vary with aperture and eyepiece selection
http://astro.unl.edu/classaction/ani...elescope10.swf
2CCD Simulator
Shows a rainfall and bucket analogy to CCD imaging
http://astro.unl.edu/classaction/ani...es/buckets.swf
3Snell's Law Demonstrator
Demonstrates Snell's Law, a formula that describes how light is refracted when it moves between different media
http://astro.unl.edu/classaction/ani.../snellslaw.swf

Sun and Solar Energy
1Proton-Proton Animation
Shows an animated diagram of the proton-proton chain reaction, which is the dominant fusion reaction in the sun's core
http://astro.unl.edu/classaction/ani...y/fusion01.swf
2CNO Cycle Animation
Shows an animated diagram of the CNO cycle, which dominates in stars larger than the sun
http://astro.unl.edu/classaction/ani...y/fusion02.swf
1Distance Modulus ExplorerStellar Properties
Shows how the distance modulus formula combines apparent and absolute magnitudes to give the distance to a star
http://astro.unl.edu/classaction/ani...stellarmag.swf

2Stellar Velocity Calculator
Shows how the distance to a star, its doppler shift, and its proper motion allow one to calculate the star's true space velocity
http://astro.unl.edu/classaction/ani...stellarvel.swf
3Parallax Calculator
Diagrams the geometry and shows the math involved in determining a star's distance via parallax
http://astro.unl.edu/classaction/ani...rallaxdiag.swf
4Spectroscopic Parallax Simulator
Demonstrates how the technique of spectroscopic parallax works. Spectral type and luminosity class determine the observed spectrum of a star, from which the star's luminosity can be estimated
http://astro.unl.edu/classaction/ani...roparallax.swf

5Stellar Luminosity Calculator
Demonstrates how a star's luminosity depends on its temperature and radius
http://astro.unl.edu/classaction/ani...stellarlum.swf
6Flux Simulator
Demonstrates the inverse square law of light with a lightbulb and detector. The lightbulb's intensity and the detector's distance can be adjusted to see how they affect the reading. There are two bulbs and detectors to allow side-by-side comparisons
http://astro.unl.edu/classaction/ani...htdetector.swf
7HR Explorer -NAAP
Introduces the Hertzsprung-Russell Diagram, a plot showing the relationship between luminosity and temperature for stars
http://astro.unl.edu/classaction/ani...hrexplorer.swf

Binary and Variable Stars
1Eclipsing Binary Simulator
Models the motions of two stars in orbit around each other, and the combined lightcurve they produce. This simulator allows the user to control multiple parameters to see how they effect the lightcurve. Includes several real datasets
http://astro.unl.edu/classaction/ani...gbinarysim.swf
2Aliasing in Wagon Wheels
Demonstrates aliasing through the analogy of a wagon wheel being filmed. For some combinations of frame rates and true rotation speeds the wheel can appear to rotate backwards
http://astro.unl.edu/classaction/ani...wagonwheel.swf
3Center of Mass Simulator
Shows how the center of mass of two objects changes as their masses change
http://astro.unl.edu/classaction/ani...nterofmass.swf
4Lightcurve Simulator
Shows how a lightcurve is constructed from observations of an eclipsing binary system
http://astro.unl.edu/classaction/ani...lightcurve.swf

1Milky Way Rotational VelocityMilky Way Galaxy
A plot of the rotational velocity of stars at varying distances from the center of the milky way. A draggable cursor allows determining the contained mass implied by the curve
http://astro.unl.edu/classaction/ani...alvelocity.swf
2Traffic Density Analogy
The build-up of traffic behind a slow moving tractor provides an analogy to the density wave formation of spiral arms
http://astro.unl.edu/classaction/ani...ficdensity.swf
1Balloon UniverseCosmology
An animation of coins attached to a balloon, providing an analogy to the expansion of the universe. The coins represent galaxies, which maintain their scale while the space between them grows
http://astro.unl.edu/classaction/ani...gy/balloon.swf
2Galactic Redshift Simulator
Demonstrates the redshift of a galaxy due to the expansion of the universe, and the effect this shift has on the galaxy's brightness as observed through various filters
http://astro.unl.edu/classaction/ani...icredshift.swf

Solar System Characteristics
1Planet Formation Temperatures Plot
Shows planet formation temperature as a function of distance from the Sun. Also indicates the state (gas or solid) of several substances at the given distance and temperature
http://astro.unl.edu/classaction/ani...ationtemps.swf
2Solar System Properties Explorer
Allows one to explore a set of histograms for characteristics like number of satellites, mass, orbital period, etc. for the terrestial and jovian planets, plus Pluto
