N\u00fc\u00fcd on sul v\u00f5imalus otsida asteroide just nii, nagu astronoomid seda teevad!<\/p>\n<\/div>\n<p>Selle l\u00fchifilmi on salvestanud Jaapani kosmoseteleskoop AKARI. See n\u00e4itab Maa l\u00e4hedal asuvat asteroidi Itokawa \u2013 keskel asuvat heledat laiku \u2013, nagu seda n\u00e4eb AKARI infrapunakaamera. Asteroidi suhteline l\u00e4hedus Maale ilmneb selle kiirest liikumisest 12-minutilise ajavahemiku jooksul. Selle heledus on seotud ka selle infrapuna- (soojus-) kiirgusega. (Selliseid andmeid kasutatakse, et saada parem \u00fclevaade nende asteroidide suurusest, mis v\u00f5ivad \u00fchel p\u00e4eval sattuda kokkup\u00f5rkekursile Maaga.)<\/p>\n<p>Itokawa ei ole selles videos ainus kosmosekivi. Lisaks on n\u00e4ha ka kahte palju n\u00f5rgemat asteroidi, mis liiguvad aeglaselt \u00fcle taeva. \u00dcks neist tiirleb sarnases suunas nagu Itokawa. Kas sul on piisavalt kannatlikkust ja oskusi, et need \u00fcles leida? Pane t\u00e4hele, et videol paistavad t\u00e4hed vilkuma. Selles filmis n\u00e4idatud pildid on t\u00f6\u00f6tlemata, just sellised, mida astronoomid ise teadust\u00f6\u00f6s kasutavad. Selgelt on n\u00e4ha palju kriimustusi ja triipe, mis on tekkinud kosmiliste kiirte ja muude m\u00f5jude t\u00f5ttu.<\/p>\n<p>Kui see video 26. juulil 2021. aastal salvestati, asus Itokawa Skorpioni t\u00e4htkujus. Sel hetkel olid asteroid ja Maa \u00fcksteisele k\u00f5ige l\u00e4hemal, neid eraldas umbes 42 miljonit km. (V\u00f5rdluseks: Maa asub P\u00e4ikesest 150 miljoni km kaugusel.)<\/p>\n<p>Kontrolli oma vastuseid<\/p>","protected":false},"excerpt":{"rendered":"<p>Have you ever wondered what it is like to be a professional astronomer, searching through spacecraft data in search of new worlds?
