Spiral galaxy M101
This giant spiral disk of stars, dust and gas is 170,000 light-years across, or nearly twice the diameter of our Milky Way galaxy. M101 is estimated to contain at least one trillion stars. About 100 billion of them could be similar to our Sun. This is one of the largest and most detailed photo of a spiral galaxy that has been released from Hubble. The galaxy's portrait is actually composed of 51 individual Hubble exposures, in addition to elements from images from ground-based photos. Cleaned and retouched image, original by "ESA/Hubble (M. Kornmesser), warped and recoloured by NN"
