| | Globular Star Clusters |
 | | This discovery was followed by that of southern Omega Centauri (NGC 5139) by Edmond Halley on his 1677 journey to St. |
 | | Since their discovery and resolution, globular clusters were always thought or suspected to be physical objects, agglomerations or swarms of stars held together by their mutual gravity, all close together and at about the same distance. |
 | | These galaxies contain also extremely large diffuse nebulae with masses of the order of globular clusters, clear candidates for future young globulars currently in formation, notably the Tarantula Nebula NGC 2070 in the LMC and NGC 604 in M33. |
