About This Episode

The universe is awash with radiation, from long wavelength radio waves to short wavelength gamma rays. The entire electromagnetic spectrum is not perceptible to us—the human eye can only detect visible light waves—but space telescopes and other technology act as our spy-glasses on the invisible realm. Michael Benson, Brian Abbott and Carter Emmart discuss the different ways they use data collected from the Hubble Space Telescope and our other mechanical eyes in the sky to reveal the artistic majesty of the cosmos. Neil and Lynne discuss light’s biography, from its birth in the Big Bang to the dying of the light at the end of time.

Episode Topics

  • Ty

    Were you and I listening to the same podcast? I kept expecting Neil to interrupt her and go, “Quiet sweetie, adults talking here!”

    • craiggnt

      I could not stand listening to the whole podcast because of the girl running her mouth.

  • Paulo

    Is there a link to the archives where Michael Benson get’s his raw images from? He mentions he encourages others to do it and I’ve had poor luck finding a good archive repository from NASA.

    • Jeff

      Paulo, I’m not sure if this is exactly what you’re looking for, but if you go to this page http://search.nasa.gov/search/search.jsp?nasaInclude=images and search “all NASA sites” you can usually find some great images.

        Why would Mike be invited to the show if Tyson was going to shut him down?

    Holy buckets Lynne! Don’t get me wrong, I love some of your question, but seriously, the constant interruption and hogging the show was not cool…
