Physicist Stephen Hawking has released a new iPad app to let budding physicists learn about the lives of stars and planets.
The app, called Snapshots of the Universe, allows users to create their own solar systems, drop objects to learn about gravity, learn about Einstein's theories of relativity and hunt for black holes in the constellation of Leo.
Snapshots of the Universe, which was released last month, is Stephen Hawking's first foray into apps, and is geared for all ages.
