NGC 6240 offers a rare, nearby glimpse of a cosmic catastrophe in its final throes. The titanic galaxy-galaxy collision takes place a mere 400 million light-years away in the constellation Ophiuchus. The merging galaxies spew distorted tidal tails of stars, gas, and dust and undergo fast and furious bursts of star formation. The two supermassive black holes in the original galactic cores will also coalesce into a single, even more massive black hole and soon, only one large galaxy will remain. This dramatic image of the scene is a composite of narrowband and near-infrared to visible broadband data from Hubble’s ACS and WPC3 cameras, a view that spans over 300,000 light-years at the estimated distance of NGC 6240.

🌌 NGC 6240 提供了一個難得的近距離視角，讓我們目睹宇宙大災難的最後階段。這場巨大的星系碰撞發生在距今僅400萬光年的位置，位於蛇夫座（Ophiuchus）。這兩個星系的合併產生了扭曲的潮汐尾巴，伴隨著大量的恆星、氣體和塵埃，且快速而劇烈的恆星形成過程正在上演。原本星系核心中的兩個超大質量黑洞也將合併成一個更為龐大的黑洞，最終只會剩下一個大型星系。這幅壯觀的影像是Hubble的ACS和WPC3相機用窄帶和近紅外到可見光寬帶數據合成而成，描繪的場景橫跨超過30萬光年，見證了NGC 6240的奧秘。✨
