This research was presented in a paper entitled «Connecting the dots: a correlation between ionising radiation and cloud mass - loss rate traced by optical integral field spectroscopy,» by A. F. McLeod et al., published in the Monthly Notices of the Royal Astronomical Society.

«But once the atom is ionised, the electrons don't just leave their atom like a train leaves a station, they still feel the electric field of the laser,» explains Jean - Pierre Wolf, a professor at the applied physics department of the UNIGE Faculty of Sciences.

The more intense a laser is, the easier should it be to ionise the atom — in other words, to tear the electrons away from the attracting electric field of their nucleus and free them into space.

Since the charge is concentrated over a small distance, it would create a strong electric field, perhaps enough to ionise the air and create a luminous discharge that travels up away from the ground — explaining the orbs, flames and aurora - like sheets of light.

But Hayabusa has been hobbling home without the full use of its four ion engines, which ionise xenon gas and then use electric fields to accelerate the ions, providing a steady — though weak — thrust.

The sun's radiation ionises the water molecules, the team say, which then get swept up by the planet's magnetic field and channelled down to Saturn.

Earth's magnetic field also traps gas escaping from the upper atmosphere after it gets ionised by ultraviolet light from the sun.

When the radio waves pass through the galaxy, a region in which there is both a magnetic field and ionised gas, the direction of polarisation is changed, or «rotated».
