Vénus, Soleil, CME

FARSIDE CME: There is an active sunspot on the farside of the sun. Yesterday, Feb. 25th, it blasted a coronal mass ejection (CME) over the sun's northwestern limb, shown here in a movie from the Solar and Heliospheric Observatory:

A 3D model of the CME prepared by analysts at the Goddard Space Weather Lab shows that the CME will miss everything--no planets are in the line of fire.

NASA's STEREO-Ahead spacecraft is stationed over the farside of the sun, almost directly above the CME. Images from the spacecraft pinpointed the source of the blast: It is active sunspot AR1678, which rotated off the Earthside of the sun just a few days ago.
