费米卫星眼中的γ射线天空，更确切的说，γ射线脉冲星。

Fermi's Gamma-ray Pulsars

NASA, DOE, Fermi LAT Collaboration
美国宇航局、美国能源部、费米卫星大区域望远镜协同工作组（从后文看我猜LAT是 Large Area Telescope）
Explanation:
Born in supernovae, pulsars are spinning neutron stars, collapsedstellar cores left from the death explosions of massive stars.Traditionally identified and studied by observing their regular radiopulsations, two dozen pulsars have now been detected at extremegamma-ray energies by the Fermi Gamma-ray Space Telescope. Thedetections include 16 pulsars identified by their pulsed gamma-rayemission alone. This gamma-ray all-sky map, aligned with the plane ofour Milky Way Galaxy, shows the pulsar positions, with the 16 new Fermipulsars circled in yellow (8 previously known radio pulsars are inmagenta). Bizarre stellar corpses, the Vela, Crab, and Geminga pulsarson the right are the brightest ones in the gamma-ray sky. Pulsars Taz,Eel, and Rabbit are named for the nebulae they are now known to power.The Gamma Cygni and CTA 1 pulsars at the left also reside withinexpanding supernova remnants of the same name.
脉冲星是诞生于超新星爆发的高速旋转的中子星，是大质量恒星晚期剧烈爆发后的残余核心，传统上通过有规律的射电脉冲辐射辨识和研究它们。现在，费米γ射线空间望远镜已经发现了2打发出高能γ射线的脉冲星，其中的16个已经通过它们独立的γ射线脉冲辐射被（新）确认为脉冲星。
本图是γ射线的全天区图，图中横亘的亮区是我们银河系的银道面。图中用黄圈标出了费米卫星新发现的16个脉冲星（8个早先辨认出的用品红色圈标识）。图中右边的几个亮γ射线源是：船帆座γ射线源(Vela)、蟹状星云（Crab）和双子座γ射线源。另外几个脉冲星以被它们所激发的遗迹星云命名——小胡子、鳗鱼和兔子。（不好意思，我不知道这几个星云，但英文应该是这个意思——gohomeman1译注） 图左，天鹅座γ射线源和CTA 1脉冲星也位于同名的超新星遗迹中。
