For most of human history, planetary systems were a sample size of one. Ours. Then people learned about Mercury, Venus, Mars, Jupiter, and Saturn since antiquity, tracking their movements for generations. Uranus joined the planetary roster in 1781 thanks to the telescope, followed by Neptune in 1846, but every planet we discovered still belonged to the same family orbiting our Sun.

08:02CDTA study funded by NASA, and published in The Planetary Science Journal, has determined that the Moon's radius has decreased by about 45 meters. The scientists' analysis concluded that this reduction occurred over the last 400 to 800 million years. Every million years, according to the report's estimates, the Earth’s satellite’s radius would shrink by between 6 and 11 centimeters. In other words, 0.1 micrometers (0.0001 millimeters) per year. Aside from this fact, the research funded by the U. S. space agency has identified more than 10,000 faults on the Moon as a result of studying images from the Lunar Reconnaissance Orbiter, in orbit since 2009. This finding could pose a setback for exploration of the satellite: NASA is considering establishing a lunar base with basic infrastructure in 2032. Until then, efforts are focused on determining possible locations for the installation. The large number of faults detected goes beyond mere scientific curiosity, as it could pose a setback for future crewed missions. The reason is that, unlike the Earth, with 15 major tectonic plates, the Moon has a single plate.

Currently, about 16,000 satellites are orbiting Earth, providing everything from GPS service and weather reports to phone service in remote locations to people across the globe. In contrast, the highest-ever number of active satellites in orbit around Mars, one of the best-explored other planets in our solar system, is eight.

The only thing we can be sure of about the future is that it will be absolutely fantastic. If what I say seems reasonable to you, then I have failed completely, declared Arthur C. Clarke back in 1964 on the BBC. In the legendary BBC Horizon documentaries more than 60 years ago, Clarke made several predictions—including some about the Internet that proved uncannily accurate.

AbstractKagome superconductors AV3Sb5 (A = Cs, K, Rb) host intertwined orders arising from electronic correlations and lattice geometry, but the nature of the high-temperature electronic state from which these phases emerge remains poorly understood. Although numerous experiments have reported rotational symmetry breaking, it is still intensely debated whether this may be a simple consequence of the symmetry of the underlying 2  × 2 charge density wave (CDW) or an entirely different mechanism. Here we use spectroscopic imaging scanning tunneling microscopy to track the evolution of electronic structure in CsV3Sb5 as the CDW is intentionally suppressed through two distinct chemical substitution routes—Sn on the Sb site and Ti on the V site.
