While orbiting the sun, NASA's STEREO-A spacecraft has taken a look back at Earth, to also find Mars and Pluto in shot.
Physicists have now provided the first major results of NASA's Magnetospheric Multiscale (MMS) mission, including an unprecedented look at the interaction between the magnetic fields of Earth and the sun.
The Sun is capable of producing monstrous eruptions or "superflares" that can not only break down radio communication and power supplies, but also affect the Earth's ability to support life.
Physicists have firmed up a theoretical limit on the mass of a black hole by figuring out when it will disrupt the disc that feeds it.
Lasers could heat materials to temperatures hotter than the centre of the Sun in only 20 quadrillionths of a second, according to new research.
The leading edge of the first of two major coronal mass ejections will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours). Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes, with possible disruption to high frequency radio communication, global positioning systems (GPS), and power grids.
On August 9, 2011 at 3:48 a.m. EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite. This was the largest flare of

Massive waves in giant magnetic holes on the surface of the Sun have been discovered for the first time by solar scientists, something that will bring experts a step closer to unlocking the secrets of the Sun.
A powerful solar flare has ushered in the largest space weather storm in at least four years and has already disrupted some ground communications on Earth.
The Sun has unleashed its strongest flare in four years, observers say.
First ever STEREO images of the entire Sun
On August 1, 2010, an entire hemisphere of the sun erupted. Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space. Astronomers knew they had witnessed something big. It was so big, it may have shattered old ideas about solar activity.
