NASA STEREO - SECCHI July 30 - August 12, 2010

SECCHI is a suite of remote sensing instruments consisting of two white light coronagraphs (COR1 and COR2) and an EUV imager (EUVI), collectively referred to as the Sun Centered Imaging Package (SCIP), and a Heliospheric Imager (HI). Each STEREO spacecraft has almost identical configuration. STEREO Ahead and STEREO Behind.

SECCHI will follow three-dimensional Coronal Mass Ejections (CMEs) from birth at the Sun's surface, through the corona and interplanetary medium, to impact at Earth. We anticipate major breakthroughs in understanding the origin and consequences of CMEs, in determining their three-dimensional structure, in identifying the magnetic configurations and evolutionary paths leading to CMEs, in determining the key factors controlling their trajectories, and in achieving the national goal of predicting space weather.

Watch the CMEs from early August. On SECCHI A (left side of the screen) you can see Mercury and Venus.

yeah

@oliaiguambfigues76 But at least Venus was protected by its atmosphere. Mercury has a really thin atmosphere, so it probably felt the full force of the blast.

Mercury isn't a nice place to be at all, but Venus is even worse. Venus has clouds of sulphuric acid, the atmospheric pression on the surface is 92 times heavier than on earth and the average temperature is of 463º Celsius. I doubt that man will ever be able to set foot in any of them.

Wow, that's incredible. I would've hated to be on Mercury during that. Hell, I'd hate to be on Mercury at all XD
