If you've ever wondered where the Earth came from, the answer, it seems, is blowing in the wind the solar wind. Or so say scientists who, after examining solar wind samples collected by the Genesis spacecraft, conclude that the inner planets of our solar system formed a little differently than we'd thought. The work appears in the journal Science. Our solar system arose from a large, rotating cloud of interstellar debris called the solar nebula. The sun came first and the planets followed not long after. But the new study shows that the ratio of oxygen and nitrogen isotopes found in the solar wind is different from the ratio here on earth, or on the moon or Mars. We've got more of the heavier versions of these atoms than our Sun does. Now we just have to figure out why. Scientists say the excess heavy nitrogen could have come from a comet. And the heavier oxygen from a natural process that left more of the light isotope in the part of the nebula that made the sun.

Printed "tattered", the speaker says "wondered"

Explanation: In the audio you hear "ever wondered where". They start with different letters, but both end the same, so listen to the whole word.

Printed "rightfulness", the speaker says "scientists"

Explanation: Here the speaker says "so say scientists who". They do not start with the same letter, so listen for the full word.

Printed "bigotry", the speaker says "differently"

Explanation: The speaker says "a little differently than". The spoken word is much longer than the printed one.

Printed "basswood", the speaker says "followed"

Explanation: Listen for "planets followed not". They begin with different letters, so wait for the full word before you click.

Printed "biotin", the speaker says "nitrogen"

Explanation: You will hear "nitrogen isotopes found". The printed word makes no sense in this sentence, so trust the audio.

Printed "tubercles", the speaker says "versions"

Explanation: On the recording the words are "the heavier versions of". The first letters differ, so follow the sound not the print.

"Science" matches the audio

Explanation: "appears in the journal Science." It looks like a trick. The speaker says it exactly, so do not click.

"Genesis" matches the audio

Explanation: "collected by the Genesis spacecraft." Genesis looks unusual here. The speaker says it exactly, so do not click.
