SOLAR BLAST: An enormous magnetic loop filled with glowing-hot gas lifted off the Sun at 13:19 UT on June 9th.
Astronomers call such events "prominences" -- they're caused by explosive instabilities within the Sun's tangled magnetic field.
This one stretches about 50 Earth-diameters from one end to the other.

Above: An ultraviolet telescope onboard the Solar and Heliospheric Observatory captured this spectacular view of the prominence at 13:19 UT on June 9th.
