Astrophoto Friday - the Whirlpool Galaxy

M51, the Whirlpool Galaxy, is 37 million light years distant but still a jewel of the heavens. Here it is as captured by the Palomar Transient Factory (PTF) survey using Palomar's 48-inch Samuel Oschin Telescope.

For those keeping score, the PTF survey has discovered 882 supernovae.

The Whirlpool Galaxy can be found in the northern constellation of Canes Venatici (the hunting dogs).
