The Spanish Dancer is a spiral.
Mark Hanson and Mike Selby are the authors of the image.
An island universe of billions of stars is located in the southern constellation Dorado. The Spanish Dancer galaxy is seen from our perspective. A gorgeous grand design spiral, this galaxy's two graceful spiral arms are traced by bright blue star clusters, pinkish starforming regions, and swirling cosmic dust lanes. One of the closest and bright Seyfert galaxies is the spiral of NGC 1566, which has a flaring center. It is likely to have a central black hole that iswreaking havoc on surrounding stars, gas, and dust. The stars are well within the Milky Way.
Tomorrow's picture is light-weekend.

Galileo's world.
The image is from NASA, JPL-Caltech, SETI Institute and CynthiaPhillips.
The Galileo mission discovered evidence that the moon's icy surface hides a deep, global ocean, and recorded stunning views of it. Galileo's image data has been remastered here, with improved calibrations to produce a color image approximating what the human eye might see. There is a hint at the subsurface liquid water in the long curving fractures of Europa.
Scientists confirm the water-vapor-on-europa. The moon is flexing around Jupiter, which is providing the energy to keep the ocean liquid. It is possible that even in the absence of sunlight, the process could provide the energy to support life, making it one of the best places to look for life beyond Earth. What kind of life could live in a dark ocean? Consider planet Earth's own extreme shrimp.
