It is one of the more massive galaxies known. A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This sharp view of the gorgeous island universe shows off a striking yellow nucleus and galactic disk. Dust lanes, small, pink star-forming regions, and young blue star clusters are embedded in the patchy, tightly wound spiral arms. In contrast, many other spirals exhibit grand, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, even larger than our own Milky Way and captured by this composite image merging exposures from the orbiting 2.4-meter Hubble Space Telescope and the ground-based 8.2-meter Subaru Telescope. X-ray images suggest that resulting winds and stellar explosions create plumes of hot gas extending into a halo around NGC 2841.

🌌 發現亙古星海的奇蹟！NGC 2841，這座壯觀的螺旋星系，距離我們僅有4600萬光年，位於北天的北斗七星星座（Ursa Major）。這幅清晰的影像展示了這個島宇宙的驚人美麗：明亮的黃色核心和鬆散的星系盤，裡面嵌著灰塵帶、小而粉紅色的恆星形成區域，以及年輕的藍色恆星聚集體。
與許多其他螺旋星系的宏偉螺旋臂不同，NGC 2841的螺旋臂更為緊湊，呈現出獨特的結構。這個星系的直徑超過150,000光年，甚至比我們的銀河系（Milky Way）還要大！這張合成影像是由太空中的2.4米哈勃太空望遠鏡（Hubble Space Telescope）和地面8.2米的昴宿星團望遠鏡（Subaru Telescope）共同拍攝的。
X射線影像顯示，來自星風和恆星爆炸的能量，形成了一圈在NGC 2841周圍的熱氣雲。這真是一個不容錯過的驚奇之地！✨
