Spaceflight and the radiation problem
... to Mars would be several times greater than this, perhaps as much as 20 Tesla. It has also been suggested that a magnetic field as high as 20 Tesla might itself represent a threat to the crew. Some physicists have suggested that it might be possible...

Its official! Voyager 2 has passed into interstellar space
... process regularly occurs between the Earth and Sun’s magnetic field, so it would be no surprise to find the same thing happening between the Sun’s (magnetic) field and the interstellar field. Unlike Voyager 1 however, Voyager 2 did not come across...

Superconductors - key to unlocking high power space missions
... and optimised propellant injection mechanisms. HTS can be applied to other EP technologies which also require the use of magnetic fields, such as Hall-effect thrusters and Helicon Plasma Thrusters. Here, the use of HTS enables mass reduction...

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 ...
