A compilation of various images from the James Webb Space Telescope shows the effects of gravitational lensing caused by dark matter.
When the Apollo astronauts returned from the Moon, they brought with them samples of lunar soil (regolith) and rock. The analysis of these samples forever changed our perceptions of how the Earth-Moon system formed and evolved. Similarly, the samples returned by China's Chang'e program are also leading to breakthroughs in our understanding of Earth's only satellite, especially its so-called "dark side." As a tidally-locked body, the Moon's near side is constantly facing towards Earth while its far (or "dark") side faces outward to space.
