This comic is a list of questions which [[Randall]] has about the Solar System, which at first glance may appear to be things that Randall would like to learn about.
In actual fact most of the questions have not been satisfactorily answered or proven by anyone in the {{w|List_of_unsolved_problems_in_physics#Astronomy_and_astrophysics|scientific community}}.

! Question given
! Answer given by Randall (in Red)
! Comments
|-
| Why is the the Moon so blotchy?
| Lava
| The {{w|Moon}} is in synchronous rotation with Earth, which means that we always can see only one half of the surface of the Moon. And on that side we can see large {{w|lunar mare}} formed by lava from big volcanoes. This surface is very different to all other celestial bodies we know in our Solar system. The double "the the" could be a Randallism — intended or unintended.
|-
| Why are all the blotches on the near side?
| ...
| The nearside of the Moon is dominated by the blotchy 'seas' or maria, the far side by craters. {{w|Far_side_of_the_Moon#Differences|Several explanations}} for this have been proposed, including an overabundance of impacts obliterating the blotches on the more exposed far side, different compositions of heat-producing elements, large collisions, or heat produced by the still-cooling Earth.
|-
| Did Mars have seas?
| Yes (briefly?)
| Recent explorations have confirmed there was once standing and also floating water, but not yet that long. Many rovers and orbiters on Mars give us the evidence on this early development of that planet.
|-
| Was there life on Mars?
| ...
| One of the big mysteries, not yet answered.
|-
| What's Titan like?
| Cold, yellow, lakes + rivers (methane)
| The {{w|Cassini–Huygens}} mission confirmed the presence of {{w|Lakes_of_Titan|lakes and rivers}} on Titan. The {{w|Huygens_(spacecraft)#Findings|Huygens}} lander itself returned some very yellow images of a dry lake bed from Titan's surface.
|-
| What was Earth like during the Hadean?
| ...
| The {{w|Hadean}} was the first geologic era on earth, the planet had just formed and not much is known of that period of Earth.
|-
| Is the Oort Cloud a real thing?
| ...
| The {{w|Oort Cloud}} is a theoretical spherical cloud of icy planetesimal, maybe dust, and also larger objects at a distance of up to around 100,000 {{w|Astronomical units|AU}} to our Sun. We can see similar clouds at other stars, but there is still no evidence that this cloud exists in our Solar System.
|-
| Why is the Sun's corona so hot?
| Something about magnets?
| The {{w|corona}} of the sun is hotter than it theoretically should be. The looping magnetic fields in this area could be responsible.
|-
| What are comets like?
| Precipitous
| The {{w|Philae (spacecraft)|Philae lander}} is next to a cliff...
|-
| Where's Philae, exactly?
| ...
| ...but we're not sure ''which'' cliff.
|-
| What's Pluto like?
| rowspan="2" | [Soon!]
| rowspan="2" | The probe {{w|New Horizons}} may be about to answer both of these questions.
|-
| What's Charon like?
|-
| Why don't we have in-between-sized planets?
| ...
| There is a size-gap between the rocky planets up to Earth size and the gas giants much larger than Earth.
|-
| What's Ceres like?
| [Working on it!]
| The {{w|Dawn (spacecraft)|Dawn probe}} is currently exploring the Dwarf Planet {{w|Ceres (dwarf planet)|Ceres}} and reveals unseen surface features.
|-
| Why is Europa so weird-looking and pretty?
| Ice over a water ocean
| {{w|Europa (moon)|Europa}} is a moon of Jupiter and the surface is basically thick pack ice covered in {{w|lineae}}.
|-
| Why is Io so weird-looking?
| Sulfur volcanoes (? in the wrong places?)
| The moon {{w|Io (moon)|IO}} is also orbiting Jupiter and is close enough that tidal forces make it the most volcanic object in the solar system. The bright red color comes from from {{w|sulfur}} which is ejected by the volcanoes.
|-
| Why are so many Kuiper Belt objects red?
| ...
| Many objects in the {{w|Kuiper Belt}} have a reddish hue. A possible explanation is that they are [http://www.space.com/9418-icy-red-objects-solar-system-edge-point-life-building-blocks.html| covered in organic molecules] formed by the irradiation of their surface ices. The {{w|New Horizons}} probe might also shed light on this.
|-
| What are those spots on Ceres?
| ...
| {{w|Ceres (dwarf planet)|Ceres}}
|-
| What's in the seas under Europa's ice?
| ...
| {{w|Europa (moon)|Europa}}
|-
| Which of the other moons have seas?
| Several
| (Partial/initial list possible? Definition of 'seas' would affect this.)
|-
| What are the big white things in Titan's Lakes?
| ...
| {{w|Lakes of Titan}}
|-
| What do Jupiter's clouds look like up close?
| ...
|
|-
| What's all that red stuff in the Great Red Spot?
| ...
|
|-
| What's pushing the Pioneer Probes?
| Heat from the RTG
| Discussed as the {{w|Pioneer anomaly}}. RTG stands for {{w|Radioisotope Thermoelectric Generator}}.
|-
| What pushes spacecraft slightly during flybys?
| ...
| The related {{w|Flyby anomaly}}.
|-
| Where are all the Sun's Neutrinos?
| Oscillating
| {{w|Solar neutrino problem}}
|-
| Why is there so much air on Titan?
| ...
|
|-
| Why does the Kuiper Belt Stop?
| ...
| A reference to the {{w|Kuiper Cliff}}.
|-
| Why is Iapetus weird-colored?
| ...
| {{w|Iapetus (moon)}} is a moon of Saturn and has a white side and a dark side.
|-
| Why does Iapetus have a belt?
| ...
| It also has a mountain chain along the equator.
|-
| What's the deal with Miranda?
| ...
| {{w|Miranda_(moon)|Miranda}} is the smallest of Uranus's five round satellites, and it's {{w|Verona Rupes|a bit rough around the edges}}. Also possibly a [[Firefly|''Firefly'' reference]] since {{w|List of Firefly planets and moons#Miranda|Miranda}} is the name of a planet in {{w|Serenity (film)|''Serenity''}}, a film in the {{w|Firefly (TV series)|''Firefly''}} series.
|-
| Did Uranus and Neptune change places?
| ...
| The {{w|Nice model}} is a theory of how our solar system formed, which suggested the possibility of Uranus and Neptune having swapped places before reaching their current positions. Work by Professor S. Desch [http://dusty.la.asu.edu/~desch/publications/2007/Desch2007.pdf| also came to this result].
|-
| Did the Late Heavy Bombardment happen?
| ...
|
|-
| Did life start before it?
| ...
|
|-
| Is Europa covered in Ice Spikes?
| ...
|
|-
| Why haven't we built a big inflatable Extreme Sports Complex on The Moon?
| ...
| See, e.g., ''{{w|The Menace From Earth}}'', a 1957 short story by Robert Heinlein.
|}

The title text refers to the {{w|2015 FIFA Women's World Cup}} which was won by USA a day before. The nylon wings and flying may be a reference to two passages from 3001: The Final Odyssey, one where Frank Poole tries out various wings while in an extremely low gravity environment, and one where he remarks while watching Swan Lake that Tchaikovsky could never have imagined a performance where the dancers were actually flying (due to aforementioned low gravity).

| Precipitous
| The {{w|Philae (spacecraft)|Philae lander}} is next to a cliff...
|-
| Where's Philae, exactly?
| ...
| ...but we're not sure ''which'' cliff.
|-
| What's Pluto like?
| rowspan="2" | [Soon!]
| rowspan="2" | The probe {{w|New Horizons}} may be about to answer both of these questions.
|-
| What's Charon like?
|-
| Why don't we have in-between-sized planets?
| ...
| There is a size-gap between the rocky planets (up to Earth size) and the gas giants
|-
| What's Ceres like?
| [Working on it!]
| Another probe, {{w|Dawn (spacecraft)}}.
|-
| Why is Europa so weird-looking and pretty?
| Ice over a water ocean
|
|-
| Why is Io so weird-looking?
| Sulfur volcanoes (? in the wrong places?)
|
|-
| Why are so many Kuiper Belt objects red?
| ...
| Many objects in the {{w|Kuiper Belt}} have a reddish hue. A possible explanation is that they are [http://www.space.com/9418-icy-red-objects-solar-system-edge-point-life-building-blocks.html| covered in organic molecules] formed by the irradiation of their surface ices. The {{w|New Horizons}} probe might also shed light on this.

| {{w|Ceres (dwarf planet)|Ceres}}
|-
| What's in the seas under Europa's ice?

|
|-
| What's pushing the Pioneer Probes?
| Heat from the RTG
| Discussed as the {{w|Pioneer anomaly}}. RTG stands for {{w|Radioisotope Thermoelectric Generator}}.
|-
| What pushes spacecraft slightly during flybys?
| ...
| The related {{w|Flyby anomaly}}.
|-
| Where are all the Sun's Neutrinos?
| Oscillating
| {{w|Solar neutrino problem}}
|-
| Why is there so much air on Titan?

|
|-
| Why does the Kuiper Belt Stop?

| A reference to the {{w|Kuiper Cliff}}.
|-
| Why is Iapetus weird-colored?
| ...
|
|-
| Why does Iapetus have a belt?
| ...
|
|-
| What's the deal with Miranda?
| ...
| {{w|Miranda_(moon)|Miranda}} is the smallest of Uranus's five round satellites. Also possibly a [[Firefly|''Firefly'' reference]] since {{w|https://en.wikipedia.org/wiki/List_of_Firefly_planets_and_moons#Miranda|Miranda}} is the name of a planet in {{w|https://en.wikipedia.org/wiki/Serenity_(film)|''Serenity''}}, a film in the {{w|https://en.wikipedia.org/wiki/Firefly_(TV_series)|''Firefly''}} series.
|-
| Did Uranus and Neptune change places?
| ...
| The {{w|Nice model}} is a theory of how our solar system formed, which suggested the possibility of Uranus and Neptune having swapped places before reaching their current positions. Work by Professor S. Desch [http://dusty.la.asu.edu/~desch/publications/2007/Desch2007.pdf| also came to this result].
