Ma lalo o ke alakaʻi ʻana a Sandor Kruk, mai ka Max Planck Institute for Extraterrestrial Physics, ua ʻike ʻia kahi hui honua o nā mea noiʻi, huna ʻia ma waena o nā ʻikepili i hoʻolei ʻia mai ka Hubble Space Telescope, ʻoi aku ma mua o 1.000 asteroids nona mākou i ʻike ʻole ai a hiki i kēia manawa. I loko o kahi ʻatikala hou i paʻi ʻia ma 'Astronomy & Astrophysics', ua wehewehe ka hui o nā astronomers i ka nānā ʻana i nā palapala ʻāina i hōʻiliʻili ʻia e Hubble i nā makahiki he 20 i hala, ua loaʻa iā lākou ma mua o 1.700 tracks of asteroids. Ua ʻike mua ka nui o lākou iā lākou ma mua, akā ʻoi aku ma mua o 1.000 i lilo i mea hou loa.
I ka hala ʻana o nā makahiki, ʻoi aku ka nui o nā telescopes e hoʻokō a ʻoi aku ka nui o ka nānā ʻana, e hoʻopiha ana i nā faila ʻikepili i loaʻa ʻole ka manawa e nānā ai.
Ua ʻike ʻia ua hoʻokaʻawale ʻia nā ʻike koʻikoʻi i kekahi manawa i kēlā ʻikepili e kali ana i nā ʻepekema e hoʻomohala i nā ʻano loiloi hou a me nā mea hana e ʻike ai iā lākou. ʻO ia ka mea i kūleʻa i kahi hana hui i kapa ʻia ʻo Hubble Asteroid Hunter, i hoʻokumu ʻia i ka makahiki 2019 e kahi hui o nā astronomers ma ke ʻano he papahana ʻepekema kamaʻāina ma ka platform Zooniverse. E like me kāna helu ponoʻī, ʻo ka pahuhopu ka nānā ʻana i ka ʻikepili Hubble i ka ʻimi ʻana i nā asteroids hou.
"ʻO ka ʻōpala o kekahi astronomer hiki ke lilo i mea waiwai no kekahi," wahi a Kruk. ʻO ka ʻoiaʻiʻo, ua hoʻolei ʻia ka ʻikepili i hoʻopaʻa ʻia mai nā ʻike ʻē aʻe i pili ʻole me nā asteroids a ua kapa ʻia ʻo ia he 'noise'. Akā ʻo nā ʻikepili a pau i hoʻolei ʻia a ʻaʻole i nānā ʻia e kekahi mea i mālama pono ʻia a loaʻa. "ʻO ka nui o ka ʻike i hōʻiliʻili ʻia i loko o nā waihona astronomy - wahi a Kruk- piʻi nui a makemake mākou e hoʻohana i kēia mau ʻikepili kupanaha".
No laila, ua nānā ka hui i ʻoi aku ma mua o 37.000 mau kiʻi Hubble i lawe ʻia ma waena o ʻApelila 30, 2002 a me Malaki 14, 2021. he kaha ʻōniʻoniʻo i paʻi ʻia ma ke kiʻi. He hana paʻakikī ka ʻimi ʻana i kēia mau laina haʻihaʻi no nā kamepiula, a ma laila kahi e komo ai ka platform Zooniverse a me ka ʻepekema kamaʻāina.
"Ma muli o ka orbit a me ka neʻe ʻana o Hubble ponoʻī - wehewehe ʻo Kruk - ʻike ʻia nā kukuna i nā kiʻi, he mea paʻakikī ke hoʻokaʻawale i nā ala asteroid a i ʻole, paʻakikī i kahi kamepiula ke hoʻomaopopo i ka ʻike ʻana iā lākou. No laila makemake mākou i nā mea manawaleʻa e hana i kahi papa helu mua, a laila mākou i hoʻohana ai e hoʻomaʻamaʻa i kahi algorithm aʻo mīkini. "
Ua holomua ka hana, a ua komo nā mea manawaleʻa he 11.482 i ka hoʻokaʻawale ʻana i nā kiʻi, me ka hopena o 1.488 hoʻohālikelike maikaʻi ma kahi o 1% o ka nui o nā kiʻi. Ua hoʻohana ʻia kēia ʻikepili e aʻo i kahi algorithm aʻo mīkini e ʻimi i ke koena o nā kiʻi Hubble, nāna i hoʻihoʻi i 900 mau ʻike.
A ma laila i komo hope mai ai ka poʻe kilo kilo hōkū. Me Kruk ma ke alakaʻi, nui loa nā mea kākau o ka pepa i nānā i nā hopena, me ka ʻole o nā kukuna cosmic a me nā mea ʻē aʻe. I ka hopena, aia he 1.701 i hoʻopaʻa ʻia i nā ala asteroid i koe, a ʻo 1.031 ka mea hou loa a ʻike ʻole ʻia.
Ua ʻōlelo ka poʻe noiʻi ua pakele lākou i ka ʻike ʻia no ka mea ua nāwaliwali loa lākou a ʻoi aku paha ka liʻiliʻi ma mua o nā mea i ʻike ʻia e nā telescopes honua. ʻO ka ʻatikala ka ʻāpana mua o kahi hana paʻakikī i loko o ka Hubble Asteroid Hunter initiative. I ka pae aʻe, e hoʻohana nā ʻepekema i ke ʻano curved o nā contrails e hoʻoholo i nā orbit a me nā mamao o nā asteroids hou.
"ʻO Asteroids - hoʻomau Kruk - he koena o ka hoʻokumu ʻana o kā mākou Pūnaehana Solar, ʻo ia hoʻi e hiki iā mākou ke aʻo hou aku e pili ana i nā kūlana i lanakila i loko o ka wā i hānau ʻia ai nā hōkū."
Ua hōʻoia pū ka mea noiʻi ua loaʻa i kāna hui, ma waho o nā asteroids, nā ʻikepili ʻē aʻe: "ua loaʻa kekahi mau ʻike fortuitous i nā kiʻi waihona, a ke aʻo nei mākou iā lākou". Akā ʻaʻole makemake ʻo Kurk e hōʻike i ka ʻike o kēia mau ʻike ʻē aʻe. No ia mea, e kali iki kakou.
