Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

NASA’s IXPE space observatory has examined the polarization of X-rays from the supernova wreckage Cassiopeia A to learn more about its powerful magnetic fields.

Scientists believe the Sun’s magnetic field could reverse within our lifetime, a natural cycle that occurs roughly every 11 ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity.. Over the past couple of years, solar activity ...

What happens when the universe's most magnetic object shines with the power of ... This illustration depicts IXPE’s measurements of X-ray polarization emitting from magnetar 1E 1841-045 located ...

One of these components is magnetic polarity, which refers to the direction of the Earth’s magnetic field at a particular location and time.

As co-author Jianfeng Zang explains, the microfibrebots are made by using thermal energy to draw magnetic soft composite materials into microfibres, which are then “magnetized and moulded to give them ...
