Nasa has released these stunning images of the Sun which show the biggest solar flare of the year.
The huge eruption on April 11th caused a temporary radio blackout on Earth, officials say.
However, they warn the worst is yet to come – with this year expected to see the sun reach its 11 year solar maximum.
Nasa’s Solar Dynamics Observatory captured this image of an M6.5 class flare at 3:16 EDT on April 11, 2013. The huge eruption on April 11th caused a temporary radio blackout on Earth, and is the biggest of the year so far, officials say

The solar flare occurred at 3:16 a.m. EDT (0716 GMT) and registered as a M6.5-class sun storm, a relatively mid-level flare on the scale of solar tempests.
It coincided with an eruption of super-hot solar plasma known as a coronal mass ejection.
‘This is the strongest flare seen so far in 2013,” NASA spokeswoman Karen Fox explained in a statement.
‘Increased numbers of flares are quite common at the moment, since the sun’s normal 11-year cycle is ramping up toward solar maximum, which is expected in late 2013.’
Humans have tracked this solar cycle continuously since it was discovered, and it is normal for there to be many flares a day during the sun’s peak activity, Nasa said.
Officials dubbed today’s solar flare as a ‘spring fling’ for the sun, which has been relatively calm as it heads into its peak activity period.
The M6.5 flare on the morning of April 11, 2013, was also associated with an Earth-directed coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later.
The joint ESA/NASA Solar Heliospheric Observatory (SOHO) captured this series of images of the coronal mass ejection (CME) on the morning of April 11, 2013 over the course of 3:48 EDT to 4:36 EDT. Mars can be seen on the left
