NASA Scientists Find Clues That Life Began in Deep Space Images

Figure 1
Figure 1 and 2. Pyranene dye encapsulated in various sizes of vesicles made from a room temperature residue from the above described simulations. They are viewed at 400x via fluorescence microscopy (excitation = 400-430; emission = 450-520). Note that in figure 1 both the bright fluorescence of encapsulated pyranine and the dimmer autofluorescence of the residue can be seen.

Figure 3 and 4. The residue was separated into its its component molecules (via chromatography) Figure 4 is a more polar fraction shown in fluorescence (see above). Figure 3 is a less polar fraction shown via phase microscopy.
