Ko te PSR B1257+12 i kitea e te kaitātai whetū o Pōkehā a Aleksander Wolszczan i te 9 o Hui-tanguru 1990 mā te whakamahi i te pouaka whakaata Arecibo. He pūwhero mētara, he momo whetū neutron, me te wā hurihanga o 6.22 mētara (9,650 rpm), ā, i kitea he rerekētanga i roto i te wā pūwhero, i arahina ai ki ngā rangahau mō te take o ngā pūwhero taupatupatu. I te tau 1992 i whakaputaina e Wolszczan rāua ko Dale Frail tētahi pepa rongonui mō te kitenga tuatahi o ngā aorangi i waho o tō tātou pūnaha solar. Mā te whakamahi i ngā tikanga whakahirahira, i kitea tētahi atu aorangi e huri ana i tēnei pūwhero i te tau 1994. Pātai: Nā wai i kitea a PSR B1257+12?
