Sun Research Yields Unexpected Results 197
Syberghost writes "There are two major theories about the composition of the Sun. One says that it has similar composition to the planets. The other, that it has enriched levels of oxygen-16. NASA has been doing research on the soil samples Neil Armstrong brought back from the moon, to determine which of those theories is correct. Today, we have the results; they're both wrong. It looks like we're going to have to look more closely at the composition of everything in the solar system to figure this one out."

It's common knowledge that the moon is made of cheese, and we all know that the sun is yellow.
What color is cheese?
There's your connection, right there.

The stuff in the corona is injected from the photosphere: basically the Sun's visible "surface". There's a lot of convection in the upper layers of the Sun, so apart from the core (where helium "ash" builds up), it's probably reasonably well-mixed.

Until: 1-We invent time travel and can go back and see how the solar system really started
You don't have to exist in the past to observe the past. In fact, the past is the only thing we are able to observe.
or 2-We discover something that can be the basis of a repeatable experiment
Astronomy is based on repeatable experiments. I don't really have any idea why you'd think otherwise.

The probe crashed because an accelerometer was upside down, but the data was mostly unaffected. It was September 2004, so, not that long ago.
