Glossary term: 超大質量黑洞
Description: 顧名思義,超大質量黑洞(SMBH)是最大的一類黑洞,其質量是太陽質量的數百萬到數十億倍不等。觀測證據表明,所有大型星系的中心似乎都蘊藏著一個超大質量黑洞。銀河系就有一個名為人馬座 A*的超大質量黑洞,其質量約為太陽質量的 450 萬倍,直徑約為 4000 萬公里。大量的質量集中在小體積中導致黑洞具有巨大的引力場(深重的引力勢阱)。自 2019 年以來,科學家們利用分布在世界各地的射電望遠鏡網絡的數據,拍攝了超大質量黑洞事件視界的圖像。截至2023年初,已經以這種方式成像了兩個超大質量黑洞:人馬座A和位於距離地球超過5000萬光年的星系M87中心的超大質量黑洞(質量是太陽的65億倍)。
