Nasa's Juno probe captures dramatic first close-up images of Jupiter

Excitement greets pictures of giant, chaotic weather systems plus new measurements that will help build unprecedented map of planet's interior

The first close-up observations from Nasa's Juno spacecraft have captured towering clouds, swirling cyclones and dramatic flows of ammonia that drive giant weather systems on the largest planet in the solar system.

The $1.1bn probe swung into orbit around Jupiter in July last year on a mission to peer through the thick clouds that shroud the planet and learn how the alien world, and ultimately all of the planets in the solar system, formed around the nascent sun 4.5bn years ago.
