Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. One of the brightest members of the Virgo Cluster of galaxies, M100 (alias NGC 4321) is 56 million light-years distant toward the constellation of Berenice’s Hair (Coma Berenices). This Hubble Space Telescope image of M100 was made in 2009 and reveals bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe. If you know exactly where to look, you can find a small spot that is a light echo from a bright supernova that was recorded a few years before the image was taken.

🏞️ 以宇宙的壯麗為背景，M100 被稱為「大設計螺旋星系」，它擁有超過 1000 億顆星星，擁有明確的螺旋臂，和我們的銀河系相似。 🌌 M100（別名 NGC 4321）是處於室女星團中最明亮的成員之一，距離我們約 5600 萬光年，位於伯尼基髮型的星座中。這幅由哈勃太空望遠鏡於 2009 年拍攝的 M100 圖像，顯示出耀眼的藍色星團和錯綜複雜的塵埃帶，這些都是這類星系的標誌。 ✨ 研究 M100 中的變星對確定宇宙的大小和年齡具有重要意義。如果你仔細觀察，還能找到一個小點，那是幾年前所記錄的亮超新星的光回聲。 🌠
