Planetary nebulae are shells of gas emitted from dying stars, while supernova remnants are the shredded remains of exploded stars, returning enriched material to the ISM for recycling into a new generation of stars. Approximately half of the mass of the ISM is contained in dense clouds composed mainly of molecular hydrogen (H2 ). These molecular clouds also contain over 100 different compounds including water, formaldehyde, alcohol (both the rubbing and drinking varieties), sugar, and even amino acids, the building blocks of life.

But this is no cause for celebration. The star is forever banished from the main sequence, and this is just part of the star’s dying process. The interior of the star is not stable, and the outer layers expand out into space, swelling the star’s size to as much as the diameter of Earth’s orbit. As the star’s outer layers move farther from the hydrogen fusion they cool, and take on a reddish tinge. 7 on p. 104). As the core continues to collapse and heat up, it eventually reaches another critical temperature.

It takes a specific amount of energy for the electron to “jump” to the first excited state, and unless the electron absorbs a photon of just the right energy (with just the right wavelength), there will be no transition. The absorbed photon will create an absorption line in the spectrum of the light passing through this collection of atoms. Likewise, there is another specific amount of energy (and hence another corresponding wavelength of light) associated with a transition to the second excited state, the third, 15 16 Cosmology 101 and so on.
