تلسکوپ فضایی جیمز وب تونست اولین سیاهچاله ای که در جهان شکل گرفته رو رصد کنه. این یک رکورد تاریخیه. سیاهچاله ای که بعد از 470 میلیون سال از شکل گیری کیهان بوجود اومده. در کنار این سیاهچاله یکی از دورترین کهکشان های کشف شده را دید که بسیار دور افتاده است و تقریبا در لبه جهان قابل روییت قرار دارد. از اون عجیب تر این بود که جرم این سیاهچاله 40 میلیون برابر خورشیده و ده برابر سیاهچاله مرکز کهکشان راه شیری ماست. به نظر می رسد این یافته یکی از مهم ترین اسرار نجوم را حل کرده است: منشا اولین سیاهچاله ها در جهان. اما چگونه چنین سیاهچاله عظیمی به این سرعت در جهان نوزاد شکل گرفت؟ این کشف بزرگ چه اطلاعات مهمی رو به ما میده؟ منابع: https://webb.nasa.gov/ Bogdán et al.
