NASA's Hubble Space Telescope has directly photographed evidence of a Jupiter-like exoplanet in the process of forming.
 
The discovery supports the less popular theory of formation by "disc instability" in the dusty material surrounding a young star.
 
Rather than building up size by slowly accumulating material, this planet appears to be forming from the disk itself as it cools and breaks up.
 
The planet is forming very far from its star – more than twice the distance from the Sun to Pluto – where building up material quickly is difficult.
 
Together with the ground-based Subaru Telescope, Hubble provided 13 years of data to support a formally underdog theory of Jupiter-like planet formation.
