The first part of our Astrobio class put into song to the tune of "White Lines".
Enjoy, or at least try to!

(ooo light)

(Light! Oooo light!)

(Visible Light) A narrow range in wavelength

(that our eyes can see) 400 to 700 nm

(Spectrum) change in wavelength frequency

(change in energy) shorter wavelength, more energy

(gamma ray, x-ray, UV, optical, infrared, radio)

(each photon carries energy)

Light! Waves!

Time to learn astrobiology

Planets, solar system, and the galaxies

Atomic structure and isotopes

About Planck's Law and Hubble's slope

Absorption and emission lines

Parallax and the speed of light

If you want to hear what I will teach

You can learn about worlds out of your reach

(Astro! Biology! Astro! Biolgy! Astro! Biology! Astro! Biology!) Go!

(Ahhh) Higher temps

(Ahhh) Higher temps

(Ahhh) Higher temps

Molecules are getting down!

Protons equal positive

Neutrons equal none

Electrons equal negative, equal negative, equal negative..

(spectroscopy) analysis of light

(like intensity) absorption and emission lines

(allow us) to measure fundamental qualities

(like density) and temperature and motion

Best tool for finding planets

Orbiting other stars, and determine

If there's life?

(Spectro-scopy!)

only in certain orbits

electrons are allowed

Orbits change by gaining or losing

Energy in fixed amounts

Absorption's when electrons

Move to a higher level

Emission puts off energy

Because it is less stressful

(Photo! Ionization! Photo! Ionization!)

(Ahhh) higher levels

(Ahhh) moving to higher levels

(Ahhh) moving to higher levels

Needs more energy

(Thermal Radiation) Has two important laws

(Like Planck's law) and don't forget Wien's Law

(Hotter blackbodies) peak at shorter wavelengths

(and emit more energy) across all the wavelengths

When something producing light

Moves toward us or away

Wavelengths shrink and stretch

Causing a visible change

When it's heading in our direction

The light starts to look blue

If it's looking red

It's moving away from you

To say the object's changing

Would not be correct

The apparent change is wavelengths is

The Doppler Effect

Doctor Hubble discovered

Redshifts in the sky

He concluded that the galaxies were telling us good-bye

But that did not make sense

So we searched for more answers

What we found is really

And expanding universe
