2023年6月7日 · First, spiral galaxy M94 has an inner ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow. A leading origin hypothesis holds that an elongated knot of stars known as a bar rotates in M94 and has generated a burst of star formation in this inner ring.

梅西耶94 （也稱為 M94 或 NGC 4736）是位於 獵犬座 的一個 螺旋星系 ，於1781年被 皮埃爾·梅香 發現 [6]，並被 梅西耶 編入其目錄中。 雖然有些參考資料描述M94是一個 棒旋星系，但 棒狀 的結構看起來比較像卵型 [7]。 這個星系已因為有雙重的環狀結構而著名 [2]。 M94的核被歸類為 低電離星系核 （Low-ionization nuclear emission-line region，LINER） [8]。 LINER的一般特徵是在光學的 譜線 上顯示有 離子 的氣體存在，但只是微弱的被游離（意思是原子只少了幾個電子） …

2025年3月6日 · A popular target for earth-based astronomers, the face-on spiral galaxy is about 30,000 light-years across, with spiral arms sweeping through the outskirts of its broad disk.
