The year 2025 delivered remarkable visuals from space exploration, including a rare double-detonating supernova and a successful private moon landing. Astronomers and space agencies captured moments ranging from rocket tests to lunar eclipses, showcasing advances in observation and technology. These images underscore a year of triumphs and challenges in the cosmos.
In 2025, astronomers using the European Southern Observatory’s Very Large Telescope in Chile imaged a two-toned sphere of gas and dust, evidence of a double-detonating supernova. Researchers at the University of New South Wales in Canberra, Australia, believe this formed when a white dwarf star exploded after drawing helium from a companion star. The initial blast occurred about 300 years ago and might have lit up the southern hemisphere's night sky, had the sun not obscured it from Earth.
SpaceX's Starship rocket faced a mixed year, achieving a successful orbital test flight in August after three prior failures that ended in explosions, termed 'rapid unscheduled disassemblies' by the company. In January, chef James Temple photographed the seventh test's fiery reentry as colorful streaks over the Turks and Caicos Islands. Meanwhile, SpaceX excelled in crewed missions, with a Dragon capsule splashing down near dolphins in the ocean, returning two NASA astronauts who had spent nine months on the International Space Station due to safety issues with Boeing's Starliner.
A milestone came in March when Firefly Aerospace's Blue Ghost lander touched down in the moon's Mare Crisium basin after a 45-day trip. As the second commercial lunar lander and the first to land upright, it captured a selfie showing its shadow against the sunlit surface, with Earth appearing as a tiny dot overhead.
The Vera C. Rubin Observatory commenced operations, producing an early image of the Trifid Nebula, a star-forming region 5,000 light years away, alongside the nearby Lagoon Nebula at 4,000 light years. This composite blended 678 exposures taken over seven hours.
September's lunar eclipse painted the moon red as it passed through Earth's shadow, a phenomenon akin to red sunsets caused by atmospheric light diffraction. A composite photograph from Tokyo tracked its path across the sky, capping a year of vivid cosmic spectacles.
