Apod- a cat's eye nebulae

This nebulae is over three thousand light years away. This image was taken by the hubble space telescope, and it reveals one of the most complex planetary phenomenon known to man. In fact, the features seen in the Cat's eye are so complex that astronomers suspect the bright central object may actually be a binary star system.

APOD-Mercury Transit

This is a picture of the transit of mercury taken by astronomer Phil Jones. The composited image was taken through a telescope equiped with an H-alpha filter that narrowly transmits only the red light from hydrogen atoms. Pictures taken this way capture a detailed picture of the solar chromosphere, the region above the Suns normally visible surface. Mercury is seen as a little black dot on the left center of this picture.
