Europos kosmoso agent\u016bros teleskopas \u201eEuclid\u201c paskelb\u0117 itin didel\u0117s apimties nauj\u0105 steb\u0117jim\u0173 rinkin\u012f, o astronomai kvie\u010dia visuomen\u0119 prisid\u0117ti prie paie\u0161k\u0173. Tikslas \u2013 atpa\u017einti gravitacinius l\u0119\u0161ius, kai masyvios galaktikos ar j\u0173 spie\u010diai i\u0161kreipia tolimesni\u0173 objekt\u0173 \u0161vies\u0105.<\/p>\n
\u0160is rei\u0161kinys kyla d\u0117l to, kad mas\u0117 i\u0161kreipia erdv\u0117laik\u012f, tod\u0117l \u0161viesa keliauja \u201eu\u017elinkusiu\u201c keliu. Kai objektai i\u0161sid\u0117sto beveik idealiai vienoje linijoje, teleskopuose matomi \u0161vytintys lankai ar net vadinamieji Ein\u0161teino \u017eiedai \u2013 tai ne iliuzija, o realus \u0161viesos nukrypimas.<\/p>\n
Ie\u0161koma per pilie\u010di\u0173 mokslo projekt\u0105 \u201eSpace Warps\u201c, vykdom\u0105 \u201eZooniverse\u201c platformoje. Dalyviams nereikia nei teleskopo, nei fizikos i\u0161silavinimo: u\u017etenka per\u017ei\u016br\u0117ti pateiktus vaizdus ir pa\u017eym\u0117ti \u012ftartinus i\u0161linkimus, kurie gali rodyti gravitacin\u012f l\u0119\u0161\u012f.<\/p>\n
\u201eEuclid\u201c \u0161ioje duomen\u0173 laidoje apima apie 72 000 000 galaktik\u0173 \u2013 tai ma\u017edaug 30 kart\u0173 daugiau nei ankstesniame pradiniame rinkinyje. Kadangi tokios apimties med\u017eiagos vien profesional\u0173 komandai per\u017ei\u016br\u0117ti ne\u012fmanoma, \u012f darb\u0105 \u012ftraukiami savanoriai, o automatizuoti modeliai padeda atsirinkti kandidatus.<\/p>\n
DI jau atrinko apie 300 000 galim\u0173 atvej\u0173, kuriuos verta tikrinti detaliau, ta\u010diau \u017emogaus akis vis dar i\u0161lieka labai stipri atpa\u017e\u012fstant netaisyklingus, subtilius lankus. Astronomai tikisi, kad \u0161i kampanija gali atne\u0161ti daugiau nei 10 000 nauj\u0173 gravitacini\u0173 l\u0119\u0161i\u0173 \u2013 tai b\u016bt\u0173 daugiau, nei j\u0173 buvo aptikta per vis\u0105 ankstesn\u0119 astronomijos istorij\u0105.<\/p>\n
Tokie radiniai svarb\u016bs ne tik d\u0117l \u012fsp\u016bding\u0173 vaizd\u0173: gravitaciniai l\u0119\u0161iai veikia kaip nat\u016bralios \u201esvarstykl\u0117s\u201c, leid\u017eian\u010dios \u012fvertinti galaktik\u0173 bendr\u0105 mas\u0119, \u012fskaitant tamsi\u0105j\u0105 med\u017eiag\u0105. Sukaupus dideles toki\u0173 sistem\u0173 imtis skirtingais Visatos raidos etapais, galima tiksliau tirti, kaip augo kosmin\u0117s strukt\u016bros ir kaip su Visatos pl\u0117tra siejama tamsioji energija.<\/p>\n
Projekt\u0173 k\u016br\u0117jai pabr\u0117\u017eia, kad pilie\u010di\u0173 mokslas jau ne kart\u0105 \u012frod\u0117 savo vert\u0119, kai didel\u0117s apimties duomenyse reikia greitai atpa\u017einti pasikartojan\u010dius, bet ne visada taisyklingus ra\u0161tus. \u201eEuclid\u201c atveju kiekvienas pa\u017eym\u0117tas kandidatas tampa papildomu ta\u0161ku, padedan\u010diu sudaryti tikslesn\u012f gravitacini\u0173 l\u0119\u0161i\u0173 katalog\u0105 ateities tyrimams.<\/p>\n
Prisijungti gali kiekvienas norintis: u\u017etenka smalsumo ir keli\u0173 minu\u010di\u0173 per dien\u0105. Mokslininkai tikisi, kad b\u016btent visuomen\u0117s \u012fsitraukimas pad\u0117s grei\u010diau \u201ei\u0161sijoti\u201c duomenis ir surasti re\u010diausias, did\u017eiausi\u0105 mokslin\u0119 vert\u0119 turin\u010dias sistemas.<\/p>\n","protected":false},"excerpt":{"rendered":"
