What is News?

For three days it was the number one story on cnn.com - right there, front and center on the screen when you loaded the page. It's still the first story listed in the "top stories" list at the right of the page today. The local news broadcast here covered the story yesterday in their 5:00 report, their 6:00 report and their 11:00 report. It was the first story reported on during the ABC Nightly News and was the main story for Nightline last night. I just don't get it. A woman, romantically obsessed with a male co-worker, goes after a female co-worker who she perceives as a rival - what makes this front page, national news? I don't care that she is astronaut. Sure - it is a prestigious and honorable profession, but so what? Can anyone explain this to me? Because I just don't get it.
