That would mean a star is between the the Moon <strong>and</strong> the Earth.<br />

Our fictionalized movie scene has some dreadful astronomy in it,<br />

<strong>and</strong> we haven’t even touched on black holes, star birth, <strong>and</strong> what<br />

nebulae really look like. But what movies have good astronomy?<br />

Any astronomer will instantly reply: 2001: A Space Odyssey. In<br />

that movie, for example, the spaceship moves silently through<br />

space (a fact they evidently forgot when making the sequel 2010:<br />

the Year We Make Contact). There are countless other examples.<br />

An astronomer once told me that the only mistake in the movie is<br />

when one of the characters, on his way to the Moon on the PanAm<br />

shuttle, takes a drink <strong>from</strong> his meal <strong>and</strong> you can see the liquid in<br />

his straw go back down after he finishes sipping. Since there is no<br />

gravity on the shuttle, the liquid would stay drawn up in the straw.<br />

This is nit-picking at an almost unbelievable level, <strong>and</strong> I think we<br />

can forgive the director.<br />

Surprisingly, the TV show The Simpsons commonly has correct<br />

astronomy. There is an episode in which a comet threatens to collide<br />

with the Earth. The comet is shown being discovered by an<br />

amateur (our antihero, Bart). Most comets are indeed discovered<br />

by amateurs <strong>and</strong> not professionals. Bart then calls the observatory<br />

to confirm it, which is also the correct procedure (he even gives<br />

coordinates using the correct jargon). When it enters the Earth’s<br />

atmosphere, the comet is disintegrated by all the smog in the air of<br />

the Simpsons’ overdeveloped city. That part can be chalked up to<br />

comedic license, but then comes an extraordinary scene: The part<br />

of the comet that gets through the pollution is only about the size<br />

of “a Chihuahua’s head,” <strong>and</strong> when it hits the ground, Bart simply<br />

picks it up <strong>and</strong> puts it in his pocket. As we saw in chapter 15, contrary<br />

to common belief, most of the time a small meteorite will not<br />

be burning hot when it hits the ground. The rock (or metal) is initially<br />

moving very rapidly through the upper atmosphere, which<br />

will melt the outer layers, but friction very quickly slows the rock<br />

down. The melted parts get blown off <strong>and</strong> the remaining chunk<br />

will only be warm to the touch after impact. In this episode of The
