梅西耶84（也稱為M84或NGC 4374）是室女座的一個w:透鏡狀星系。M84位於室女座星系團人口稠密的核心區域。^[3]

無線電觀測和w:哈勃太空望遠鏡對M84的影像揭示了從星系中心射出的兩股物質噴流，以及靠近星核的快速旋轉的氣體和恆星盤，表明該星系核心中存在著一個質量為18 ×10⁸ M_☉^[4]的超大質量w:黑洞。

歷史

w:查爾斯·梅西耶於1781年3月18日在夜空中系統地尋找“星雲狀天體”時發現了梅西耶84^[5]。該天體在w:梅西耶星表中排名第84位。

超新星

在M84中已觀測到兩顆w:超新星：w:SN 1957^[6]和w:SN 1991bg.^[7] 可能，第三顆w:SN 1980I是M84的一部分，或者，它可能屬於其鄰近星系之一，w:NGC 4387和M86.^[8]
