Aurora chasers are on high alert for possible geomagnetic storm conditions Oct.3 through Oct. 5 with northern lights possible ...

While the storm could pose a threat to fragile electric systems, the National Oceanic and Atmospheric Administration says the ...

Allowing for the changes, this key component of Atlantic heat transfer appears to be much more robust than previously thought ...

The storm should arrive today or tomorrow, and could bring with it some brilliant aurorae.

Solar flares are massive releases of energy from the Sun, associated with sunspots. Sunspots are darker because they are ...

As a result, more energy enters Earth's field, causing stronger geomagnetic storms than usual for a given CME. Stock image of a CME hitting the Earth's magnetic field (main) and NASA SOHO image of ...

NASA's BioSentinel gathers important information about solar radiation while Earth witnesses stunning auroras.

When CMEs impact Earth's magnetosphere - the region of space surrounding our planet that is dominated by its magnetic field - they can cause major disturbances called geomagnetic storms.

But the CME will only glance off the planet's magnetosphere, or the region of space around a planet dominated by its magnetic field. Normally, this slight blow wouldn't trigger a geomagnetic storm.

relative to Earth's magnetic field. Data from SWPC suggests that may not be the case, which could mean that despite a severe geomagnetic storm, an aurora would not be visible.The fields can ...

The Earth is expected to experience a geomagnetic storm this week following the autumnal equinox. A sunspot erupted on Sunday, generating a coronal mass ejection (CME) on a trajectory toward Earth.

September could be a prime time to see vibrant auroras, thanks to a quirk of Earth's tilt that leads to more intense geomagnetic activity around the equinox. There's no guarantee, but there are ...
