我们提出了一个新的行星状星云，第一次确定的图像从澳大利亚望远镜紧凑阵列，虽然没有认识到在那个时候。斯皮策太空望远镜在GLIMPSE Legacy计划期间的最新观测重新发现了该物体。高分辨率的无线电和红外图像能够识别中心星星或其风，识别无线电发射为热辐射，以及源内和周围可能存在的多环芳烃。因此，G313.3+00.3是一个行星状星云。这个天体特别令人感兴趣，因为它是完全通过无线电和中红外成像发现的，没有任何光学（或近红外）确认，并作为发现更多高度熄灭的行星状星云的概念证明。G313.3+00.3被两种仪器很好地分辨出来，并且由于它位于盾牌-Crux旋臂中而遭受极端的变红。
We present a new planetary nebula, first identified in images from the Australia Telescope Compact Array, although not recognized at that time. Recent observations with the Spitzer Space Telescope during the GLIMPSE Legacy program have rediscovered the object. The high-resolution radio and infrared images enable the identification of the central star or its wind, the recognition of the radio emission as thermal, and the probable presence of polycyclic aromatic hydrocarbons in and around the source. These lead to the conclusion that G313.3+00.3 is a planetary nebula. This object is of particular interest because it was discovered solely through radio and mid-infrared imaging, without any optical (or near-infrared) confirmation, and acts as a proof of concept for the discovery of many more highly extinguished planetary nebulae. G313.3+00.3 is well resolved by both the instruments with which it was identified and suffers extreme reddening due to its location in the Scutum-Crux spiral arm.
