 And NASA confirms that a big boom in the sky over the New York area Tuesday was a small meteor flying 38,000 miles per hour. Bill Cook with NASA's Meteoroid Environment Office says meteors are usually very hard to see in the daylight, but this one was seen by thousands of people. And something when it's moving that fast, of course, heats up and it begins to ablate, you know, just like a spacecraft reentering the atmosphere. And it produces a lot of light and it generates what we call fireballs.
