The Wider Image: The matador...Spanish matador Jose Maria Manzanares holds his bullfighter's "muleta" during a bullfight at the Real Maestranza bullring in the Andalusian capital of Seville, southern Spain April 9, 2016. At the Real Maestranza arena the crowd enjoys a tradition that dates back over a thousand years. Wearing an embroidered gold and white outfit and wielding a long thin sword, the matador taunts the 600-kilo bull with his cape, dodging its horns again and again. Despite the full stands at the bullring, which hosted its first fight in 1761, the sport attracts an increasingly slim audience, as new generations shun what they see as a cruel and unfair fight. Matadors say those who oppose bullfighting don't understand the bullring's intimacy or the artistry of the fight. To finish off the bout, matadors deliver the "estocada," a deft strike through the bull's shoulder blades to pierce its heart. REUTERS/Marcelo del Pozo   SEARCH "EL MATADOR" FOR THIS STORY.

This NASA image obtained April 15, 2016 ...This NASA image obtained April 15, 2016 shows The spider part of The Spider and the Fly" nebulae, IC 417 in star formation, as seen in this infrared image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS).  Located in the constellation Auriga, IC 417 lies about 10,000 light-years away. It is in the outer part of the Milky Way, almost exactly in the opposite direction from the galactic center. A cluster of young stars called "Stock 8" can be seen (centerR). The light from this cluster carves out a bowl in the nearby dust clouds, seen here as green fluff. Along the sinuous tail in the center and to the left, groupings of red point sources are also young stars. In this image, infrared wavelengths, which are invisible to the unaided eye, have been assigned visible colors. Light with a wavelength of 1.2 microns, detected by 2MASS, is shown in blue. The Spitzer wavelengths of 3.6 and 4.5 microns are green and red, respectively.  / AFP PHOTO / NASA/JPL-CALTECH/2MASS / Handout / XGTY/RESTRICTED TO EDITORIAL USE-MANDATORY CREDIT"AFP PHOTO/NASA/JPL-CALTECH/2MASS"- NO MARKETING NO ADVERTISING CAMPAIGNS-DISTRBUTED AS A SERVICE TO CLIENTSHANDOUT/AFP/Getty Images
