我们利用 SELENE 的两个高分辨率相机（地形相机和多波段成像仪）的数据，在月球上发现了一个垂直的洞，这可能是熔岩管天窗。该洞接近圆形，直径 65 m，位于马吕斯山地区的一条蜿蜒的沟渠中，马吕斯山地区是月球近侧的一个火山省。我们在不同的太阳光照条件下观察了这个洞，估计其深度为 80 至 88 m。深度/直径比比典型的撞击坑大得多。既没有明显的沉积物表明该洞有火山喷发，也没有邻近该洞的坑坑，这些坑可能与下面的断层或岩脉有关。洞周围的区域被一层薄薄的（20 至 25 m）熔岩层覆盖，这可能有助于保护熔岩管免于因陨石轰击而塌陷。引文：Haruyama, J. 等人。 (2009)，SELENE 相机观测到的可能的月球熔岩管天光，Geophys。资源。快报，36，L21206，doi：10.1029/2009GL040635。
We discovered a vertical hole on the Moon, which is a possible lava tube skylight, using data from SELENE's two high-resolution cameras: the Terrain Camera and the Multi-band Imager. The hole is nearly circular, 65 m in diameter, and located in a sinuous rille at the Marius Hills region, a volcanic province on the lunar nearside. We observed the hole at various solar illumination conditions and estimated its depth to be 80 to 88 m. The depth/diameter ratio is much larger than for typical impact craters. There are neither conspicuous deposits indicating volcanic eruptions from the hole, nor are there pit craters adjacent to the hole that could be related to an underlying fault or dike. The area around the hole is covered by a thin (20 to 25 m) lava sheet, which may help protect the lava tube from collapse due to meteorite bombardment. Citation: Haruyama, J., et al.
