Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Maybe the Moon owns our hearts , but this won't stop the occasional asteroid from sending us a valentine . Friday, to the surprise of many, the NEAR mission on approach to asteroid 433 EROS photographed what appears to be a heart-shaped depression . After NEAR reaches the asteroid today, NASA plans a series of maneuvers to make the robot spacecraft the first ever to orbit an asteroid. More detailed pictures will soon be taken of the 33 kilometer long asteroid EROS and this 5 kilometer long depression.
