This huge swirling mass of stars, gas, and dust occurs near the center of a nearby spiral galaxy. Gorgeous spiral NGC 3521 is a mere 35 million light-years distant, toward the constellation Leo. Spanning some 50,000 light-years, its central region is shown in this dramatic image, constructed from data from the Hubble Space Telescope. The close-up view highlights this galaxy’s characteristic multiple, patchy, irregular spiral arms laced with dust and clusters of young, blue stars. In contrast, many other spirals exhibit grand, sweeping arms. A relatively bright galaxy in planet Earth’s sky, NGC 3521 is easily visible in small telescopes, but often overlooked by amateur imagers in favor of other Leo spiral galaxies, like M65 and M66.

這個巨大的螺旋星雲，包含恆星、氣體和塵埃，位於鄰近螺旋星系的中心地區。美麗的螺旋星系 NGC 3521 僅距離我們 3500 萬光年，位於獅子座。這幅驚人的圖片是由哈勃太空望遠鏡的數據構建而成，顯示出它的中央區域，橫跨約 5 萬光年。特寫鏡頭突顯了這個星系特有的多條不規則、斑駁的螺旋臂，這些螺旋臂交織著塵埃和年輕的藍色恆星團。相比之下，許多其他螺旋星系展示的是宏偉、流暢的螺旋臂。作為地球上相對明亮的星系，NGC 3521 在小型望遠鏡下容易可見，但往往被業餘天文愛好者忽視，因為他們更喜愛其他獅子座的螺旋星系，如 M65 和 M66。
