I-European Southern Observatory (ESO) ibika ukubhaliswa kwesiganeko esibaluleke kakhulu kwimbono yesayensi ayinakulinganiswa. Ngethuba lokuqala, ukwakheka kwento enzima ngexesha lokungqubana kweenkwenkwezi ze-neutron zirekhodwe.
Kuyaziwa ukuba iinkqubo zokwakhiwa kwezinto zenzeka ikakhulu ngaphakathi kwiinkwenkwezi eziqhelekileyo, kugqabhuko-dubulo lwe-supernova okanye kumaqokobhe angaphandle eenkwenkwezi ezindala. Nangona kunjalo, kude kube ngoku bekungekacaci ukuba kwenzeka njani into ebizwa ngokuba yi-neutron ekhawulezayo, evelisa ezona zinto zinzima kwitafile yeperiodi. Ngoku lo msantsa uvaliwe.
Ngokutsho kwe-ESO, kwi-2017, emva kokubona amaza axhuzulayo afikelela eMhlabeni, i-observatory iqondise iiteleskopu zayo ezifakwe eChile kumthombo wazo: indawo yokudibanisa inkwenkwezi ye-neutron GW170817. Kwaye ngoku, ngenxa ye-X-shooter receiver kwi-ESO's Very Large Telescope (VLT), kuye kwenzeka ukumisela ukuba izinto ezinzima zenziwe ngexesha leziganeko ezinjalo.
βUkulandela umnyhadala we-GW170817, iqela leeteleskopu ze-ESO zaqalisa ukubeka esweni ukugqabhuka kwe-kilonova kuluhlu olubanzi lwamaza. Ngokukodwa, uchungechunge lwe-kilonova spectra ukusuka kwi-ultraviolet ukuya kwindawo ekufutshane ne-infrared yafunyanwa kusetyenziswa i-X-shooter spectrograph. Sele uhlalutyo lokuqala lwale mbonakalo yacebisa ubukho bemigca yezinto ezinzima kuzo, kodwa kungoku nje izazi ngeenkwenkwezi ziye zakwazi ukuchonga izinto ezizimeleyo, βutshilo upapasho lwe-ESO.
Kwavela ukuba i-strontium yenziwa ngenxa yokungqubana kweenkwenkwezi ze-neutron. Ngaloo ndlela, "ikhonkco elilahlekileyo" kwi-riddle yokubunjwa kwezinto zamakhemikhali zizaliswe.
