Giant magnetic spots discovered on small super-hot stars
...sunspots on our own Sun. Although both are caused by magnetic fields, not only are EHB spots significantly larger than sunspots, covering..., it could also help explain the origin of strong magnetic fields in many white dwarfs; a small very dense star ...

Telescope targets enigmatic deep space mystery
... Molonglo radio telescope’s observations has helped confirm the extragalactic nature of one-off FRB events Secondly, magnetic fields play very critical roles in almost every aspect of astrophysics, ranging from star formation to large-scale galactic...

Plumes on Europa - tasting an extra-terrestrial ocean
.... This variation is linked to Europa’s movement relative to Jupiter’s magnetic field. It is possible therefore that Jupiter’s magnetic field is inducing a corresponding magnetic field via a conductive layer - made from a salty ocean - under...

Ultimate sunbather: NASA and ESA collaborate on Solar Orbiter
... analysis and predictions. A number of the instruments are designed to monitor the magnetic field of the Sun and so they need to be protected from any magnetic fields generated by the spacecraft. The spacecraft electronics and motors are a potential...

Surviving radiation for space colonisation
... Moon, Mars or elsewhere. On Earth we are protected from radiation by the mass of the Earth itself, then by the magnetic field and finally the atmosphere. Low Earth orbit (LEO), where the International Space Station is located, is protected...

Solar superstorms and their effects on Earth
.... Today, we know Carrington was observing a white light flare produced by a reconnection of magnetic field lines just above the sunspot. This reconnection reconfigured a magnetic loop, that had extended through the sunspot and to the solar atmosphere...
