Globular clusters are present in the halo that surrounds many galaxies and are essentially satellites of the parent galaxy. They are mostly composed of very old stars with low metallicity, classed as early generation (Population II) stars. M13 is one of the brightest globulars in our sky.

Palm Sunday at Church of the Resurrection, Wheaton, IL.
A reenactor shows off the only piece of waterproof gear issued to the soldiers in the landing craft.
Cantigny Park in Wheaton commemorated the 70th anniversary of the D-Day landings with vehicles, reenactors and a series of engaging activities so that young people could learn the history in engaging ways. As a special treat, there were veterans of the beach landings who were there to share their experiences and answer questions.

et aussi ma premiere image de ce magnifique amas globulaire
situé dans la constellation D'Hercule.
M13 est situé à une distance relativement « proche » de la Terre, à 22 000 années-lumière, il regroupe plus de 500 000 étoiles dans un diamètre d’à peine 150 années-lumière.
M13 serait l’un des plus vieux objets de notre galaxie ; son âge étant estimé à au moins 12 milliards d’années.
