In some locations, the Sun can actually set, rise again, and set once more, creating a rare double sunset. This surreal effect comes from Mercury’s unique 3:2 spin–orbit resonance, where the planet rotates three times for every two orbits around the Sun. At the boundary betwee

BepiColombo time lapse shows Mercury surface in unparalleled detail 🌑 The European Space Agency have released a time lapse of all the images from BepiColombo's recent Mercury flyby, its last before it starts orbiting the solar system’s innermost world in late 2026. Since launching in 2018, the joint European-Japanese BepiColombo spacecraft has flown by Mercury six times, using each successive approach to reduce its speed and adjust its flight path to make it easier to get into orbit. While the
