This is Earth calling..
This wonderful radio signal was broadcast toward the star cluster M13 in 1974 during the dedication of the Arecibo Observatory, to date the largest radio telescope in the world. To obtain any possible radio response to this ceremonial message, we've to live another 50,000 years.

Just a series of 1's & 0's representations of information about humanity. Included are the numbers from 1 through 10 (white dots/dashes, extreme left), common elements like Hydrogen and Carbon, few interesting molecules (think the green ones), DNA (the blue helix), a human with description (the red one) and the purple representation of the sending telescope.

Chakra...I saw the documentary on TV, and it is really amazing watching the foetus just fiddling around the womb, twiddling its thumbs, playing with its nose or with the umbilical cord, or just bouncing off the walls of the uterus.
Krish...this pic is just an img tag referral to the same Astronomy Picture of the Day you are talking about. Easier that way than downloading to PC and uploading to Blogger via Picasa.
