An X-class solar flare -- the biggest class of solar flare -- has erupted from the sun straight towards Earth, and geomagnetic storms are on the way.
A fascinating NASA presentation suggests that in July 2012 Earth was one week away from being struck by a massive solar storm that would have had devastating effects. Can this be?
Researchers have created pictures showing how solar storms compress our planet's protective magnetic field. The findings could help improve communications satellite design.
NASA's Juno spacecraft records footage showing how our planet and its satellite would look if visiting UFOs had really low-res cameras.
The journey would feature artificial gravity and radiation shielding, an epic trek across the Red Planet, and even a return ticket.
An enormous coronal mass ejection has sent particles into space that are due to pass the Earth in the next three days.
Scientists have taken new measurements that suggest that the core of the Earth burns at 6000 degrees Celsius — as hot as the surface of the sun.
Listen to the sound of the Earth from space, as recorded by NASA's Radiation Belt Storm Probes.
NASA's Solar Dynamics Observatory (SDO) has captured a gorgeous image of a massive eruption that could engulf the Earth several times over.
New observations from the agency's STEREO spacecraft have provided researchers with a first-ever view, end-to-end and in three dimensions, of the impact of a solar storm on Earth.
