zachycen\u00e9 v Parkes Observatory (New South Wales) roku 1998, naz\u00fdvan\u00e9 \u201eperytons\u201c (1) nepoch\u00e1z\u00ed z vn\u011bj\u0161\u00edho vesm\u00edru, ale p\u0159i\u0161ly z mikrovlnn\u00e9 trouby, z kuchyn\u011b zam\u011bstnanc\u016f. Emily Petroff, astrofyzik ze Swinburne University of Technology a jej\u00ed kolegov\u00e9 ozn\u00e1mili tuto novinku 9.4.2015 v M\u011bs\u00ed\u010dn\u00edch zpr\u00e1v\u00e1ch kr\u00e1lovsk\u00e9 astronomick\u00e9 spole\u010dnosti, a tak h\u00e1danka skon\u010dila po sedmn\u00e1cti letech.

„Byly zde t\u0159i mikrovlnn\u00e9 trouby u teleskopu. Jedna byla ve v\u011b\u017ei pod teleskopem, druh\u00e1 v n\u00e1v\u0161t\u011bvnick\u00e9m centru a t\u0159et\u00ed v kuchyni pro pracovn\u00edky v budov\u011b zn\u00e1m\u00e9 jako Woolshed. K dispozici byly i dv\u011b mikrovlnky v prostor\u00e1ch pozorovatel\u016f, ve vzd\u00e1lenosti asi jeden kilometr,“ napsala Emily Petroff a jej\u00ed t\u00fdm. „Tyto dv\u011b trouby jsou zodpov\u011bdn\u00e9 za v\u011bt\u0161inu nebo v\u0161echny zachycen\u00e9 sign\u00e1ly, a jsou od stejn\u00e9ho v\u00fdrobce (Matsushita), a i kdy\u017e slou\u017eily 27 let, perfektn\u011b fungovaly,“ dodala.<\/p>\n

V\u011bdci se domn\u00edvali, \u017ee zachycen\u00e9 sign\u00e1ly m\u011bly mimogalaktick\u00fd p\u016fvod. Dne 19. ledna 1998 austral\u0161t\u00ed astronomov\u00e9 poprv\u00e9 zaznamenali tyto sign\u00e1ly na radioteleskopu Parkes. Pot\u00e9, co se tento jev opakoval je\u0161t\u011b dvakr\u00e1t, zah\u00e1jili vy\u0161et\u0159ov\u00e1n\u00ed a nakonec zjistili, \u017ee z\u00e1hadn\u00e9 sign\u00e1ly vys\u00edlala jejich mikrovlnka. Po n\u011bkolika testech zjistili, \u017ee se tak d\u011blo p\u0159i otv\u00edr\u00e1n\u00ed dv\u00ed\u0159ek trouby po jej\u00edm vypnut\u00ed. „Bylo to p\u0159ekvapen\u00ed pro n\u00e1s v\u0161echny,“ p\u0159ipustila Emily Petroff.
