火星大气是一种太阳能泵浦的激光器。这是美国宇航局戈达德空间飞行中心物理学家与天文学家穆马(Michael Mumma)所领导的一个研究组的惊人发现。他们观察到,该行星上层大气发射的10.4微米和9.4微米辐射比分子在125K时处于局部热力学平衡时所应有的亮度高10~9倍。显然,入射太阳辐射能使CO_2分子产生粒子数反转,并维持这种 Mars atmosphere is a solar-powered laser. This is a surprising finding from a research team led by physicist and astronomer Michael Mumma of NASA's Goddard Space Flight Center. They observed that the radiation emitted by the upper atmosphere of the planet at 10.4 and 9.4 microns should be 10 to 9 times brighter than the local thermodynamic equilibrium at 125K. Obviously, incident solar radiation can make CO 2 molecules produce particles to reverse and maintain this
