    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: One of the most spectacular solar sights is an explosive flare.
In 2011 June, the Sun unleashed somewhat impressive, medium-sized solar flare
as rotation carried active region [6] s of sunpots toward the solar limb. That
flare [7] , though, was followed by an astounding [8]  gush of magnetized
plasma [9]  -- a monster filament seen erupting at the Sun's edge in this
extreme ultraviolet image from NASA's Solar Dynamics Observatory [10] .
Featured here [11]  is a time-lapse video of that hours-long event showing
darker, cooler [12] plasma raining down across a broad area of the Sun's
surface, arcing along otherwise invisible magnetic field lines [13] . An
associated coronal mass ejection [14] , a massive cloud of high energy
particles, was blasted in the general direction of the Earth [15] ,and made a
glancing blow to Earth's magnetosphere [16] .
