Steve Martin has to explain to Fox News the difference between a solar system and a galaxy

Poor Fox News. They posted an article with a headline saying that a New Zealand man was the first amateur astronomer to capture a photograph of another galaxy — when in fact, Rolf Olsen had just captured an image of another solar system, Beta Pictoris. It's an easy mistake to make — galaxies and solar systems both have stars and planets in them, after all.

Enter Steve Martin, who tweeted: "A galaxy IS a solar system. According to Fox fact checking." Responded Fox: "The error was brought to the attention of FoxNews.com by famed comedian, actor and author Steve Martin — who obviously recognizes a good story when he reads it — and we have corrected the headline."
