Cat’s Paw Nebula from Webb Space Telescope

Explanation: Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat’s Paw Nebula visible toward the constellation of the Scorpion (Scorpius). At 5,700 light years distant, Cat’s Paw is an emission nebula within a larger molecular cloud. Alternatively known as the Bear Claw Nebula and cataloged as NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. Pictured here is a recently released image of the Cat’s Paw taken in infrared light by the James Webb Space Telescope. This newly detailed view into the nebula helps provide insight for how turbulent molecular clouds turn gas into stars.

韦伯太空望远镜影像: 猫掌星云

说明：就如同猫以常惹出麻烦而著称，星云也常因其形状而名闻遐迩。然而，没有任何猫能够创造出位于天蝎座方向的庞大猫掌星云。距离地球5,700光年的猫掌星云，是个镶在庞大分子云里的发射星云。编录号为NGC 6334、偶亦有熊掌星云之称的猫掌星云，在过去的数百万年里，诞生了许多高达10倍太阳质量的恒星。这幅刚发布的红外光影像，则是由韦伯太空望远镜所拍摄的。这幅呈现猫掌星云的细致新影像，有助于深入探索及了解湍动的分子云，如何把气体转化成恒星。
