Australia’s Harvest Moon and a Season of Supermoons: When to Watch and Why they Happen
Australia’s Harvest Moon Opens a Season of Supermoons Tonight’s harvest moon marks the start of a rare run of supermoons visible from Australia, with two more full moons — in November and December — also classed as supermoons. Some observers may even count a January 2026 full moon as a supermoon depending on the criteria.…

Giant Neutral Hydrogen Bridge Between Dwarf Galaxies NGC 4532 and DDO 137
Introduction: A Cosmic Jet Between Dwarf Galaxies In a landmark discovery, astronomers have revealed a colossal structure of neutral hydrogen that stretches between two nearby dwarf galaxies, NGC 4532 and DDO 137. Located about 53 million light-years from Earth, this bridge of gas is not only immense in its length but also unusual in its…

Moon Drifting Away From Earth: The Tidal Tug Revealed
Moon drifting away from Earth: the tidal reason The Moon is slowly moving away from Earth, at about 1.5 inches (3.8 centimeters) per year. This measured drift comes from precise lunar laser ranging, where lasers are bounced off corner-cube retroreflectors left on the Moon by Apollo missions and later spacecraft. Over decades of measurements, scientists…

Moon Drifting Away From Earth: The Tidal Forces Behind the Mystery
Moon Drifting Away: The Slow Recession Explained Science has confirmed a long-persisting drift: the Moon is gradually moving farther from Earth. The rate is about 1.5 inches (3.8 cm) per year, a tiny but measurable change that has intrigued scientists for decades. The figures come from Lunar Laser Ranging (LLR) experiments that bounce laser pulses…
