Default A Picture from Planet Mercury! And what is there there?

NASAhas just published the first ever orbit Messenger spacecraft picture as it orbits the planet.

Now can anyone make out what that tiny tall structure is at about 1 inch from the top and left side? Seems to have two shadows!!

More on the Messenger Spacecraft Project here.

I doubt that those are shadows of the "object", since they seem to increase in width as we go away from the object (unless they are shadows of two lights mounted near the object at the time of the photo!).

Or perhaps the object is a tall tower increasing in diameter as we go up (but then why two "shadows"?).

But they might be the result of "shading" the surrounding surface from change from some event that occurred near the object in the past.

Fabulous image in any event!

Best regards,

Doug

Maybe it's the entire Mercury civilization lives there? No doubt there will be high resolution photographs and taken with multispectral cameras so we'll soon know much more! I wonder what the scale is?

The crater is called Matabei and the two "shadows" are believed to be ejection tracks.

The 'two shadows' are actually impact ejecta.
