Launched 10 years ago, on Oct. 25, 2006, the twin spacecraft of NASA's STEREO mission – short for Solar and Terrestrial Relations Observatory – have given us unprecedented views of the Sun, including the first-ever simultaneous view of the entire star at once.

Solar winds triggered a giant geomagnetic storm this week, raising fears that they could cripple power supplies.

The charged particles are coming from a coronal hole on the sun that is currently facing Earth.

If Earth's magnetic field was hit by charged particles the effects could also include radar and satellite interference, causing problems phone and internet networks and navigation services.

Power grid operators in the US were put on alert yesterday following concerning space weather forecasts. But the impact could be felt all over the world.

Warnings were issued by the operator of the biggest power grid in the US, PJM Interconnection LLC, as well as by Midcontinent Independent System Operator, which manages high-voltage power lines across North America, reports Bloomberg.


The aurora forecast is looking favourable

Nov. 14-18, 2016 Sun was hitting its lowest level of solar activity since 2011 as it gradually marches towards solar minimum. Sun has a pendulum-like pattern of solar cycle of activity that extends over about an 11-year period. The last peak of activity was in early 2014. At this point in time, the sunspot numbers seem to be sliding downwards faster than expected, though the solar minimum level should not occur until 2021. No doubt more and larger sunspots will inevitably appear, but we'll just have to wait and see. Credit: SDO, NASA.

The Sun’s largest solar flare in more than 12 years – and the 8th largest since modern records began in 1996 – has been captured in high detail by a team of researchers from the University of Sheffield and Queen’s University Belfast.

The large solar bursts have energies comparable to one billion hydrogen bombs and can drive plasma away from the solar surface at speeds of up to 2000 km/s in phenomena known as Coronal Mass Ejections.

@Drone Is it just me or do the size of the black spots on the sun seem to be bigger than usual? End of all life incoming? :p
