Solar cowlick

Proving that even stars can have bad hair days, the sun sports a large cowlick-like eruption of plasma in a picture taken by NASA's Solar and Heliospheric Observatory and released October 29.
The solar prominence, which curled up and out near the sun's north pole, was just one of three sun eruptions that took place between October 25 and 26. None of the events were themselves unusual, although it was odd to see them grouped so closely together, according to NASA.
