NASA says we all live in a giant bubble shaped like a 'deflated croissant' - Sky News

NASA has revealed the shape of the bubble surrounding our solar system: a deflated croissant.

But the new research - which draws on data from the Voyager spacecrafts, the Cassini mission to Jupiter, and the New Horizons mission to Jupiter and Pluto - suggests the heliosphere is more a crescent shape than a comet.

Scientists studied particles flying towards Earth, particles trapped in Saturn's magnetic field, particles bouncing back towards the inner solar system, and used NASA missions' data to characterise the behaviour of material in space that fills the bubble of the heliosphere to map its boundary.
