Extrasolar Planetary Transits?

I am struck by the similarities between this image http://en.wikipedia.org/wiki/File:GJ1214b.jpg which is an artist's impression of GJ1214b and the the image provided here on GZ by the Hubble scientists.
Anyone else able to imagine this as an extrasolar planetary transit?Posted

Hi Mike,
This is not a planetary transit. Planets can't be seen this far away. Were it a planet then this one would be HUGE and luminiscent.
My guess is this is a background or foreground star.Posted

Sorry Abe, for clarification i am referring at the small black dot, not the very bright green star which may be playing host to it. I am just struck by the similarity to the artist's impression of a known object 😉

Oops, my bad....
I think the dot is an optical effect. Any planet around a star can't be seen and is lost in the star's glow.
And the picture - no matter how beautiful it is - is some form of artist's license.Posted

I keep getting out of step! Must type faster... Check this out Abe http://adsabs.harvard.edu/abs/2012ApJ...756..176H which I got from here http://exoplanet.hanno-rein.de/system.php?id=55+Cnc+f very cool catalogue!
Edit: I am working in a time warp Cap'n Abe. I'm not ignoring you, I just can't keep up. As usual lol! You're more like a red giant anyway....Posted
