Twitter index: Voyager 1, 'Insidious 2'

On Friday, September 13, Twitter users are talking about the unmanned spacecraft Voyager 1 and the forthcoming horror film "Insidious: Chapter 2."

Scientists have announced that Voyager 1 has exited our solar system, becoming the first ever manmade object to do so.

The craft was first launched in 1977 to explore the distant outreaches of our solar system and is now around 19 billion km (12 billion miles) from Earth.

Elsewhere on Twitter, "Insidious: Chapter 2," the sequel to the horror movie "Insidious," is trending after hitting cinemas in the US on September 13. The film, once again, follows the fortunes of the Lambert family, who once again fall victim to paranormal activity.

"Insidious 2" was directed by James Wan and stars Patrick Wilson and Rose Byrne as Josh and Renai Lambert. A trailer can be found at youtube.com/watch?v=fBbi4NeebAk.
