This is actually one thing I've always been wondering about as a non-native speaker when reading English headlines. Is there any reason newspapers prefer this style? It sounds weird to me.

It's weird for us native speakers too, don't worry.

My guess is that it puts the information in the title in order from the most eye-grabbing to the least. (The more readable "Google Execs and James Cameron unveil Asteroid Mining Venture" puts the holy shit part of the title at the end.)

It's very much an American newspaper thing--I've never seen it in the British press, but it seems to be house style at the New York Times and its ilk.
