这只巨大的鸡的蛋可能会形成星星。以科学指定的颜色显示的特色发射星云，编号为IC 2944，但因其更大的外观形状而被称为“小鸡星云”。在图像的底部可以看到小而暗的分子云，富含遮蔽宇宙尘埃的物质。这些“蛋”以其发现者的名字命名为“萨克雷球状体”（Thackeray’s globule），它们是新恒星引力凝聚的潜在场所，尽管它们的命运还不确定，因为它们也在被附近年轻恒星的强烈辐射迅速侵蚀。这些巨大而充满活力的恒星与斑状的发光气体和反射尘埃的复杂区域一起形成了疏散星团collon249。这幅绚丽的天景在星云估计6500光年的距离上跨越了大约60光年。

The eggs from this gigantic chicken may form into stars. The featured emission nebula, shown in scientifically assigned colors, is cataloged as IC 2944 but known as the Running Chicken Nebula for the shape of its greater appearance. Seen toward the bottom of the image are small, dark molecular clouds rich in obscuring cosmic dust. Called Thackeray's Globules for their discoverer, these "eggs" are potential sites for the gravitational condensation of new stars, although their fates are uncertain as they are also being rapidly eroded away by the intense radiation from nearby young stars. Together with patchy glowing gas and complex regions of reflecting dust, these massive and energetic stars form the open cluster Collinder 249. This gorgeous skyscape spans about 60 light-years at the nebula's estimated 6,500 light-year distance.
