Millions of people across the UK witnessed one of the best solar eclipse in years.
The sun emitted a third significant solar flare in under 24 hours, peaking at 9:11 p.m. EDT on May 13, 2013. This flare is classified as an X3.2 flare. This is the strongest X-class flare of 2013 so far, surpassing in strength the two X-class flares that occurred earlier in the 24-hour period.
The discovery of water on the moon made headlines in 2009, and a study published in the journal Nature Geoscience last week suggests that this water may have come, at least in part, from the sun.
