Mars Today 对比 Skylob 的使用情况和统计数据

Looking at searchable NASA media archives of extensive pictures, audio, and video files. Be sure to check out Mars Rover images! The observable universe is about 93 billion light years wide, approximately contained 1 billion trillion stars. Due to dark force, galaxies are accelerating faster than speed of light away from each other, and that made the cosmological horizon is about 16 billion light years (that is the furtherest we can retrieve information due to aforementioned forces). Humbled by Carl Sagan, we lived in a tiny blue dot, one of many many heavenly objects that awaits us to discover :-)
