Two galaxies sit side by side. The larger of the two galaxies, a spiral, is on the left side of image. At its center is a hazy yellow circular region from which two well-defined arms extend to form loose spirals around the middle. The arms consist of dark reddish-brown dust trails that are spotted with red stars and shrouded in a haze of blue stars. The smaller galaxy on the far-right side of the image is a hazy yellow sphere resembling the core of the first galaxy but with no spiral arms. It is about twice the size of the core in the first galaxy, but because it has no spiral arms it is much smaller. The view of this smaller galaxy is partially obstructed by the tip of one of the arms of the spiral galaxy, which appears to cover the top third of the smaller galaxy.

    Today's #Hubble favorite is M51. It's a pair of two interacting galaxies, NGC 5194, the Whirlpool Galaxy, and its companion galaxy NGC 5195. The image was taken to celebrate Hubble's 15th anniversary in 2005.

    The Whirlpool Galaxy is a grand design spiral. Its arms may be so prominent because of a series of close encounters with NGC 5195, the small, yellowish galaxy behind the outermost tip of one of its arms.
