Hey Ho, did you know?
That there's a universe in the radio
I'm gonna tell you what you want to know
About the universe in the radio
Oh well a radio photon has a low frequency
Corresponding to a deep voice like me
Foot long wavelength, how can that be?
It comes from processes having low energy
A radio photon has a low frequency
'Cause it has a pretty low energy
It was 1931 when Dr. Karl Jansky
He's the father of radio astronomy
He studied radio noise to find out what it
could be
And saw that it was coming from our own
Galaxy
He wondered what all the static could be
It was the center of the Milky Way Galaxy
I'm gonna tell you what you want to know
I'm gonna tell you what you want to know
Those long waves penetrate Earth's
atmosphere
Even if it's cloudy it's radio clear
Observatory dishes placed far and near
Let astronomers see how the waves
interfere
They penetrate through the atmosphere
Down to radio dishes placed far and near
There's a lot of cool gas in the Milky Way
Neutral hydrogen atoms leading the way
When the proton and electron spins decay
It sends a really long radio wave our way
And we study these photons day after day
To map the regions of our Galaxy real far
away
The universe began with a Big Bang explosion
Particles and energy in furious motion
Then everything expanded and the place cooled
down
To three degrees K that Penzias and Wilson found
Still some of those photons hanging around
And that's the microwave background that COBE
found
That's our Cosmic Radio Show
Of things about the universe we'd
never know
If someone hadn't built a dish and sat
below
To see the universe unfold in the radio
Hey Ho, did you know?
That there's a universe in the radio
I'm gonna tell you what you want to know
About the universe in the radio
Imagine the wonderful things that we know
By observing the sky in the radio!
The End
