Take a Spacewalk on the Wild Side : Hertzsprung Russell Diagram
Stars are so hot right now. Annie Jump Cannon, Henriette Leavitt, Antonia Maury, Florence Cushman, Cecilia Payne and others began cataloging and manually classifying stars in the late 1800's - over 350,000 of them. During that time, two astronomers simultaneously discovered a pattern in all that data. Between 1911 and 1913, Danish astronomer Ejnar Hertzsprung and American astronomer Henry Norris Russel plotted the stars recorded by Cannon and her team, and placed them on a diagram - the axes of which were the spectral classes devised by Cannon on one side, and their luminosity on the other. The diagram beautiful illustrated that in the randomness of the stars observed in the universe there is a clear pattern into which all stars fall. The diagram helps bring understanding to the temperatures and colors, brightness, sizes, and even the ages and lifecycles of the stars. Over 100 years later the diagram still holds true, and is a tool used in science today.
Traveling At The Speed Of Thought : Guest : Janet Ivey-Duensing
This episode's guest, teacher and science communicator Janet Ivey-Duesnsing from Janet's Planet, has Kovi and Benjamin traveling at the speed of thought! Listen in as Janet shares her journey from music, to science, to sparking an interest in science in thousands upon thousands of kids around the world.
What Happens On The Moon, Stays On The Moon : Telescope Evolution
Kovi and Benjamin talk about stars and planets and galaxies all the time on this show - but how do we see them? In this episode the lads discuss the evolution of the telescope - from the first lenses thousands of years ago in ancient Greece, to the curiosities of eyeglass makers in the 13th-16th centuries, to some tourist in Venice in 1609 who saw a spyglass and thought he could make a better one. That tourist was Galileo Galilei, and after he turned his own hand-made telescope skyward, word spread like wildfire. Then there were reflecting telescopes and refracting telescopes, and after a long while radio telescopes and telescopes in space!
Go, Rocket, Go! : Guest : Melody Korman
Executive Director of the Israel Space Forum, Space Mission Manager for the Rakia Mission, SpaceLab mentor and Flight Operations Manager for the Ramon Foundation, and Stargate SG-1 fanatic, Melody Korman, took time out of her ridiculously busy (and all-things-space packed) schedule to talk to Kovi and Benjamin about just some of the things she's done. From helping kids get their science experiments to space, to being the one who tells astronauts what to do, these are the things Melody calls fun.
There Was An Old Lady Who Swallowed A Tardigrade : Guest : Emily Kerrison
Blazars are just quasars that are pointed at us? That's it? Yep, that's it according to our guest, PhD candidate Emily Kerrison, in our latest, 'scintillating' episode. Do you mean 'scintillating' as in 'radio scintillation'? The same! Joining us from the University of Sydney, Australia, Emily tells Kovi and Benjamin the ins and outs of AGNs (Active Galactic Nuclei). Quasars, blazars, and BL Lac objects - oh my!
