你知道什麼是黑洞嗎？雖然黑洞在宇宙的黑暗中很難被看見，但天文學家有很厲害的方法來找到它們！他們會看看黑洞對周圍的星星和光線有什麼影響。這幅圖畫展示了一個黑洞系統，它們在進行最後的舞蹈，背景是美麗的塔蘭圖拉星雲。雖然黑洞本身不會發出光，但它們會彎曲光線的路徑，就像一個魔法透鏡一樣。這樣一來，我們就能看到扭曲的星雲，並且還會形成一些奇妙的圖案！塔蘭圖拉星雲位於大麥哲倫雲，這是一個小小的星系，距離我們160,000光年！這比我們已經發現的任何黑洞融合事件都近了超過1,000倍！不過，我們可能永遠無法發現這麼近的黑洞合併事件！

How can we see what is invisible? Black holes are not easy to see in the dark cosmic night, but astronomers can find them by analyzing their gravitational effects on matter, light and spacetime. The featured image shows an illustration that combines a simulation of a black hole binary system in its final “death-dance” with an astrophotography image of the Tarantula Nebula in the background. Even though black holes don’t emit light, they distort the path of light rays, acting like a gravitational lens. As a result, the nebula appears extremely distorted, forming Einstein rings and multiple images. Tarantula Nebula lies in the Large Magellanic Cloud, a dwarf galaxy that is one of the satellite galaxies of the Milky Way, 160,000 light-years away. That is more than 1,000 times closer than any of the binary black hole mergers detected so far. We’ll probably never detect a merger so close to home!
