Exoplanet habitability depends on a whole host of factors, with liquid water at the top of the list. It also requires a stable atmosphere, the right chemistry, and possibly even things like plate tectonics or other geological activity. Planetary magnetic fields are a critical part of the formula, too, but detecting them from Earth’s surface […] The Three-Body Problem isn’t just the name of a viral Netflix series or a Hugo Award-winning sci-fi book. It also represents a real problem in astrodynamics—and one that can cause headaches for mission planners in terms of its complexity, but also one that offers the promise of an easier way to enter stable orbits that […] Using NASA’s James Webb Space Telescope, a team led by the Southwest Research Institute (SwRI) has identified a previously unknown moon orbiting Uranus, expanding the planet’s known satellite family to 29. The detection was made during a Webb observation on Feb. 2, 2025. Go to Source A University of Queensland researcher has developed a new mathematical model to explain the evolution of the universe which, for the first time, includes collapsing regions of matter and expanding voids. Go to Source More than 50 years after the last manned moon mission, the Apollo program is still making groundbreaking discoveries. Go to Source A new kind of stellar explosion provides a novel way to probe the distant universe, according to new results published today in Nature Astronomy. Go to Source Headed for a metal-rich asteroid of the same name, the Psyche spacecraft successfully calibrated its cameras by looking homeward. Go to Source The NASA Soil Moisture Active Passive (SMAP) mission, launched in 2015, has over 10 years of global L-band radiometry observations. The low frequency [1.4 GHz frequency or 21 cm (8 in) wavelength] measurements provide information on the state of land surfaces in all weather conditions—regardless of solar illumination. Go to Source The 33rd SpaceX commercial resupply services mission for NASA, scheduled to lift off from the agency’s Kennedy Space Center in Florida in late August, is heading to the International Space Station with an important investigation for the future of bone health. Go to Source Compact, reflective, easy-to-manufacture mirrors are a critical component for advancing astronomical technology in space. Mirrors are a key component in most telescopes, though they are notoriously hard to manufacture with the necessary precision, especially at large scales. A new paper posted to the arXiv preprint server from researchers in the U.K. uses additive manufacturing to […] The exciting discovery of an extremely rare quadruple star system could significantly advance our understanding of brown dwarfs, astronomers say. These mysterious objects are too big to be considered a planet but also too small to be a star because they lack the mass to keep fusing atoms and blossom into fully-fledged suns. Go to […] Astronomers from Seoul National University, South Korea and elsewhere report the detection of 62 new luminous quasars as part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS). The discovery was detailed in a research paper published August 8 on the arXiv preprint server. Go to Source Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion of a star. Because supernovae are sudden and unpredictable, they have long been difficult to study, but today, thanks to […] New research led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models of magnetic reconnection, the process that releases stored magnetic energy to drive solar flares, coronal mass ejections and other space weather phenomena. The data was captured by NASA’s Parker Solar Probe (PSP), which is the only spacecraft to have flown through the […] A new study from the University of Nottingham has explored the use of fuel-free spacecraft propulsion systems and how they could be used in future space missions.
