P\u0159i prohled\u00e1v\u00e1n\u00ed oblohy hledaj\u00edc galaxie identifikoval kanadsk\u00fd astronom Paul Hickson se sv\u00fdmi kolegy p\u0159ibli\u017en\u011b 100 kompaktn\u00edch skupin galaxi\u00ed, kter\u00e9 se dnes p\u0159\u00edzna\u010dn\u011b naz\u00fdvaj\u00ed Hicksonovy kompaktn\u00ed skupiny. \u010cty\u0159i v\u00fdrazn\u00e9 galaxie, kter\u00e9 jsou vid\u011bt na tomto fascinuj\u00edc\u00edm teleskopick\u00e9m sn\u00edmku oblohy, tvo\u0159\u00ed jednu z t\u011bchto skupin, Hickson 44. Skupina galaxi\u00ed Hickson 44 se nach\u00e1z\u00ed ve vzd\u00e1lenosti asi 100 milion\u016f sv\u011bteln\u00fdch let, daleko za hv\u011bzdami Ml\u00e9\u010dn\u00e9 dr\u00e1hy v pop\u0159ed\u00ed, sm\u011brem k jarn\u00edmu severn\u00edmu souhv\u011bzd\u00ed Lva. Dv\u011b spir\u00e1ln\u00ed galaxie uprost\u0159ed sn\u00edmku jsou NGC 3190, viditeln\u00e1 z boku s charakteristick\u00fdmi zak\u0159iven\u00fdmi pruhy prachu, a NGC 3187 ve tvaru p\u00edsmene S. Spolu s jasnou eliptickou galaxi\u00ed NGC 3193 (vlevo) jsou tak\u00e9 zn\u00e1m\u00e9 jako Arp 316. Spir\u00e1lov\u00e1 galaxie v prav\u00e9m doln\u00edm rohu je NGC 3185, \u010dtvrt\u00fd \u010dlen Hicksonovy skupiny. Stejn\u011b jako ostatn\u00ed galaxie v Hicksonov\u00fdch skupin\u00e1ch vykazuj\u00ed i tyto zn\u00e1mky deformace a zv\u00fd\u0161en\u00e9 tvorby hv\u011bzd, co\u017e je d\u016fkazem gravita\u010dn\u00edho p\u0159etahov\u00e1n\u00ed, kter\u00e9 v kosmick\u00e9m m\u011b\u0159\u00edtku nakonec povede ke slou\u010den\u00ed galaxi\u00ed. Proces slou\u010den\u00ed je dnes pova\u017eov\u00e1n za b\u011b\u017enou sou\u010d\u00e1st v\u00fdvoje galaxi\u00ed, v\u010detn\u011b na\u0161\u00ed vlastn\u00ed Ml\u00e9\u010dn\u00e9 dr\u00e1hy.
