Several of the other "alleged" ancient phenomenon have also been explained without intervention of aliens.

    You've watched a lot of the "Leonard Nimoy Ancient Mysteries" series haven't you? Or did a parent drop you on your head when you were young?

    You douche.

    I'll take my answer off the air.
    Host TerraSapient: Holy smokes. I apologize about that last caller folks. Sometimes we attract the crazies. The Throbbing Brain encourages discussion of just about any topic related to astronomy, space travel, and the universe, but we do not condone name calling.
    Dr. Greene: Indeed!
    Host TerraSapient: Yesterday was the first I had heard of Ancient Astronaut theory. Clearly some people have very strong opinions on the matter.

    This is TS. Signing off.

    Caller: Don't listen to that RJ, he's obviously one of THEM! THEY don't want you to know the truth. Man, like I'm telling you aliens help build and design the pyramids of Egypt. The sheer number of 'coincidental' numerical relationships found in the geometrics of the pyramids clearly demonstrates that whoever built them had profoundly accurate measurements and understanding of the earth's dimensions and the solar system.

    People will miss that it once meant something to be Southern or Midwestern. It doesn't mean much now, except for the climate. The question, “Where are you from?” doesn't lead to anything odd or interesting. They live somewhere near a Gap store, and what else do you need to know? - Garrison Keillor

    The Throbbing Brain

    Host TerraSapient: Today on The Throbbing Brain we will be discussing how scientists interpret atmospheric content of planets that are hundreds of light years away!
    Dr. Greene: The technique is actually used here on Earth for a variety of analyses as well, but has proven very useful in estimating what types of gases are present surrounding planets that we are discovering in distant solar systems. This is a great tool in our search for Earth-like planets, planets that may contain liquid water, and may be habitable to ourselves or other carbon-based life forms.
    Host TerraSapient: Sounds interesting Dr. Greene. How does it work?
    Dr. Greene: As a planet passes in front of a its distant star, the light we receive from that star is dimmed, indicating that an object has blocked a portion of the photons traveling toward us through space. To find distant planets, we analyze the sky and look for this dimming effect. Once a planet orbiting a distant star has been identified, light is captured from the star as the planet passes between its star and our telescopes. That light is passed through a spectrum for analysis - much like the spectrum's we use to turn our sun's light into rainbows - producing a unique color signature. Within each individual color spectrum will be blacked out portions, almost reading like a barcode. We analyze the spectrum and search for these signature blackouts to identify what elements are present in the atmosphere of a distant planet.
    Host TerraSapient: Amazing Dr. Greene! How can you tell if the planet is habitable from that?
    Dr. Greene: Well, technically, we cannot make that determination just yet. We have to know the average temperatures of the planet by identifying the temperatures of the star, estimating how for the planet is from the star, and then try to identify if the planet is of rock or gas composition.
    Host TerraSapient: I would be interested in finding out more about the atmosphere of our diamond giant Planet Adamas. You should get started on that analysis immediately Dr. Greene!

    Let's see if our callers have anything to contribute to this discussion. The lines are open. The Throbbing Brain

    Why don't you knock it off with them negative waves?
    Why don't you dig how beautiful it is out here?
    Why don't you say something righteous and hopeful for a change?

    Are you sure you're not hurt ?
    No. Just some parts wake up faster than others.
    Broke parts take a little longer, though.

    Do you find the Transit of Venus on Tuesday more than interesting ?
