Key ideas in The Universe as It Really Is
- Stars are constant light sources that do not flicker on their own
- Earth's moving air (turbulence) bends starlight as it passes through
- The lack of an atmosphere in space means light travels in a straight, steady line
- Atmospheric effect on stars
- Stars are so far away they appear as single points of light, which are easily disrupted by air
- Planets are close enough to be seen as tiny disks, which averages out the air's distortion
- Steady light is the primary visual cue for identifying a planet without a telescope
- Distinguishing stars and planets
- The Sun emits all colors of light, which combine to look pure white
- Gravity holds air closer to the surface, making it densest at the bottom
- Whether stars actually flicker or if it is an atmospheric effect
- Earth's atmosphere scatters blue and violet light away from our eyes
- There is no physical shell or 'roof' that separates Earth from space
- Distinguishing between a star and a planet in the night sky
- The transition to space is a gradual fade-out rather than a sudden jump
- The remaining light we see from the ground is shifted toward yellow or orange

Eight weeks. You meant to finish. You didn't.
Tomo gives The Universe as It Really Is the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
