The study has been published in The Astrophysical Journal.

'This finding is a really major breakthrough, it's really set us in a direction of discovering why our model gets its distinct croissant-shaped heliosphere and why other models don't.' The neutral hydrogen particles,' Opher said. Our BU model doesn't try to cut out the chaos, which has allowed me to pinpoint the cause вЂ¦. This in turn produces large-scale turbulence in the tails of the heliosphere. Its generates a Rayleigh-Taylor instability, or an instability that occurs at the interface between two fluids of different densities when the lighter fluid pushes into the heavier one. The researchers said this happens because of the interaction of the neutral hydrogen particles with the ionized matter in the heliosheath - the outer region of the heliosphere. Using a computer model, researchers found that when the neutral hydrogen particles were taken out of the simulation, the jets coming from the sun became 'super stable'.Д«ut when they were put back, 'things start bending, the centre axis starts wiggling, and that means that something inside the heliospheric jets is becoming very unstable,' Opher said. 'We see these jets projecting as irregular columns, and have been wondering for years why these shapes present instabilities.'Д«ut when they were put back, 'things start bending, the centre axis starts wiggling, and that means that something inside the heliospheric jets is becoming very unstable,' researchers said 'Why do stars and black holes вЂ“ and our own sun вЂ“ eject unstable jets?' Opher said. The question Opher and her team wanted to answer was why it is shaped that way and how heliospheric jets become unstable. Originally scientists thought it was shaped like comet, with a round edge and long tail behind it.Д«ut data from three spacecraft that have travelled to the far reaches of the solar system вЂ“ two Voyager probes and New Horizons вЂ“ found that it is more like a croissant. Now a study led by Boston University has found the reason why this heliosphere is shaped into a pastry-like form, and it's all to do with neutral hydrogen particles from interstellar spaceДrake was part of a team of astrophysicists who carried out a study led by Boston University's Merav Opher.Д«ecause we're inside the heliosphere, this boundary of solar influence is not actually visible, making it difficult to work out its shape. 'There's lots of theories but, of course, the way that galactic cosmic rays can get in can be impacted by the structure of the heliosphere - does it have wrinkles and folds and that sort of thing?' 'How is this relevant for society? The bubble that surrounds us, produced by the sun, offers protection from galactic cosmic rays, and the shape of it can affect how those rays get into the heliosphere,' said astrophysicist James Drake of the University of Maryland. Named because they have equal amounts of positive and negative charge, therefore carrying no charge at all, these particles make the heliospheric jets unstable and cause them to bend inwards. Now a study led by Boston University has found the reason why this heliosphere is shaped into a pastry-like form, and it's all to do with neutral hydrogen particles from interstellar space. Twin jets of materialВ вЂ“ known as heliospheric jetsВ вЂ“ emanate from the sun's poles but, rather than shooting straight out, they curve round to form the solar system's tails and look like the points of a croissant. The heliosphere is created by wind and radiation from the sun as it streams outwards into interstellar space.
