High hopes for Hi-C mission to reveal secrets of the Sun
..., Hi-C captured the highest-resolution images ever taken of the solar corona to show previously unseen magnetic activity. It is thought that the Sun’s magnetic field plays a role in heating the gas in the atmosphere, which is often released into the...

New discovery provides important clues on mysterious cosmic bursts
... origin of FRBs as the team believes it may be hard to explain a 157-day precession period given the large magnetic fields expected in these stars. “Detecting a periodicity provides an important constraint on the origin of the bursts and the activity...

Hubble helps astronomers find first evidence of water vapour at Ganymede
... ribbons of electrified gas called auroral bands, and provided further evidence that Ganymede has a weak magnetic field. The similarities in these UV observations were explained by the presence of molecular oxygen (O2). But some observed features...
