This is an example of an astronomy paper I can really get my teeth into. First, it’s simple enough to understand. I like papers that I don’t understand, too, because the challenge of figuring them out is wonderful, but relatively simple ones with great information are a joy.
This one has two elements that make it particularly fun. My kind of fun I mean. I will not be upset if it’s not your kind of fun.
First, there is some technology implied and casually mentioned that is _awesome_ and demands further investigation by me. In particular, they have a 60Hz movie recording of the sky all night long that they then process entirely by computer to detect, quantify, and categorize all meteor activity. The fact that we live in a world where that’s pretty much all they need to say is mind boggling — no wonder astronomy is exploding with new information! Consider the level of manual effort that would have gone into documenting a single evening’s meteor activity. And this functionality is, I would venture to guess, well within the budget of an amateur astronomer (though we have admittedly large budgets, often).
The other thing in this paper that I can’t get enough of is great graphics. In this case great in a fairly technical sense, but look at the light curve graphs. At first it’s not all that clear what you’re looking at but as you come to understand it you find the two crucial features of excellent data visualization: in detail, there is more information than you expected and so it invites exploration and interpretation; and in general there is useful information from the gross shapes and positions of the data as a single structure.
In detail, we can see that light and altitude are compared. Looking closer, though, some points on this graph are brighter than others. Though it’s not declared explicitly, the fact that a dark background was chosen suggests to me that what they are doing is summing the hits in a particular place on the graph. So the brighter the point, the more hits from the film were in exactly that altitude/brightness spot. This kind of thing makes me want to dig deeper and deeper.
From a higher level, we can see that the shapes of these plots are similar. They are parabolas with similar widths and heights. They are all oriented the same way. They occur in roughly the same place in ranges of measured values. So this shows instantly that these are from a similar source point in the sky and probably also that they have similar composition. I expect there’s even more in here that I haven’t dug out yet.
So keep on being awesome, astronomers. Keep showing us all how it’s done.
