Solar astronomers "listening" to the Sun can now predict future sunspots
... Earth, millions of sound frequencies also bounce freely throughout the Sun’s interior, but when regions of strong magnetic fields appear, these perturb the sound waves causing a change in the wave signal measurements recorded on our planet...

Defending Earth against cosmic hazards
... four-satellite Magnetospheric Multiscale (MMS) mission are providing us more and more information about how Earth’s magnetic field is changing. The geomagnetosphere is about 15 per cent less effective in warding off the supercharged ions in a CME...

X-rays from a 'missing link' neutron star could shed light on magnetar mystery
... suddenly erupting from a regular radio pulsar? "We think these X-ray bursts happened because the object's enormous magnetic field got twisted as the object was spinning," Majid said. In a scenario analogous to tectonic plates on Earth, the stress...

Best evidence yet for plumes on Europa
...beyond Earth to search for the presence of life. The combination of the moon’s geological, compositional and induced magnetic field measurements all indicate that a salty, liquid water ocean spanning at least 100 kilometres in depth is sloshing about...
