Ua paʻi ʻia kahi hui o nā kilo hōkū ma lalo o ka malu o ka Massachusetts Institute of Technology , kahi āna i hoʻolaha ai i ka hoʻokō hou loa o kahi mikiona hou e ʻimi i nā hōkū ma waho o ka ʻōnaehana solar. Ke hoʻololi nei i ke kelepona ʻōpuni orbital Exoplanet Survey Satellite (TESS), Ma ʻApelila 18, 2018, ua ʻike ʻo ia i ka mea liʻiliʻi loa i kāna huakaʻi noiʻi pōkole - aia paha he honua pōhaku e like me ka nui o ko mākou Honua.
Hoʻopuni ka exoplanet HD 21749c i ka hōkū HD 8 me kahi manawa o nā lā 21749. ʻO ka ʻōnaehana HD 21749 he 53 mau makahiki māmā mai iā mākou. Paʻa ka hōkū ma kahi o 80% o ka nuipaʻa o ka Lā. ʻO ka ʻōpuni pōkole o ka honua a puni kona hōkū home, ʻo ia hoʻi, ʻoi aku ka nui o kona mahana ma luna o 450 degere Celsius. I ko mākou hoʻomaopopo ʻana, hiki ʻole ke ola ma luna o kēlā ʻāpana pōhaku wela. Akā ʻaʻole kēia e hōʻemi i ka kūleʻa o TESS. E hoʻomohala ʻia nā ʻenehana hulina a me nā mea hana, a manaʻo ka poʻe astronomers e loaʻa nā haneli o nā exoplanets i kahi ʻāpana ʻoluʻolu mai ke ʻano o ke ola honua.
Pono e ʻōlelo ʻia ua loaʻa i ka Kepler orbital telescope he 2662 exoplanets i loko o kāna mau makahiki he nui o ka hana ʻana, ʻo ia ka nui o ka honua. He ʻokoʻa ka mikiona a TESS. Ke aʻo nei ka telescope TESS i nā hōkū kokoke a, me nā mea hana honua ma Chile (Planet Finder Spectrograph, PFS), hiki ke hoʻoholo i ka nui a me ka hoʻohui ʻana o ka lewa o nā exoplanets me kahi kiʻekiʻe o ka pololei.
Ma luna o ʻelua makahiki, manaʻo ka misionari TESS e aʻo ma luna o nā ʻōnaehana hōkū 200. Manaʻo nā kānaka ʻepekema e kōkua kēia i ka ʻike ʻana ma luna o 000 exoplanets. Uhi ka satellite ma luna o 50% o ka lewa i loko o 90 mau lā. Ma ke ala, ua ʻike ʻia kekahi exoplanet ma ka ʻōnaehana HD 13,5 - HD 21749b. Akā aia kēia kino lani i ka papa "sub-Neptune", a ua ʻike mua ʻo TESS i kekahi mau mea like.
