Animation of a model of the appearance of the Phases of Venus in the Ptolemaic Geocentric system. The animation is a screen capture of an interactive Adobe Flash animation on the University of Nebraska's Astronomy Education ClassAction website: astro.unl.edu/classaction/animations/renaissance/ptolemaic.html Captured to video because the flash animations will be retired and removed in late 2020,...

Simulation of a star cluster Hertzsprung-Russell Diagram as the cluster evolves from 100,000 years old to 19 billion years old. The cluster has 30,000 stars with a Salpeter initial mass function and solar metallicity from 0.3 to 30 Msun. The green line is the zero-age main sequence for solar-metallicity stars. Star point sizes on the H-R diagram are scaled as the log of the stellar radius to gi...

Brief demonstration of the Doppler Effect in Sound. Recorded 2015 May 11 by Prof. Richard Pogge, The Ohio State University, Department of Astronomy.

What is the ultimate fate of the universe? The Big Bang could end either by expanding to a maximum size followed by re-collapse (the Big Crunch), or eternally expanding to a cold, dark, disordered state (the Big Chill). Which of these is our future depends on the density of matter and energy in the universe, Omega0. This lecture examines our current knowledge of the matter and energy content of...

What was the universe like from the earliest phases immediately after the Big Bang to the present day? This lecture reviews the physics of matter, and follows the evolution of the expanding universe from the first instants after the Big Bang, when all 4 forces of nature were unified in a single grand-unified superforce, through the Inflationary epoch that explains why our universe is so flat, u...

Where did Hydrogen, Helium, and all of the other chemical elements in the Periodic Table come from? Where and when did they form? Where are they still being made in the Universe? This is part 1 of a 2-part lecture exploring the origin of the chemical elements from the Big Bang to on-going stellar nucleosynthesis. A compelling scientific answer must explain in detail not only the origin of the e...

Demonstration of energy transfer between a bouncing basketball and a tennis ball dropped together, giving a physical analogy to how energy from a bouncing collapsing iron/nickel core can transfer energy to infalling gas during a core-bounce supernova. Not a exact physical analogy (i.e., no neutrino or neutron winds, it's not relativistic or billions of degrees), but it gives the idea of transfe...
