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. Go to Source In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the moon by the time China plans to land the […] Answers to some of cosmology’s most pressing questions are obscured by simple dust. It concerns the Cosmic Noon, a period of time that began around 2 billion years after the Big Bang, when nearly all galaxies experienced a burst of growth and rapid star formation. Go to Source This NASA/ESA Hubble Space Telescope image zooms in on the feathery spiral arms of the galaxy NGC 45, which lies just 22 million light-years away in the constellation Cetus (the Whale). Go to Source A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the main asteroid belt between the orbits of Mars and Jupiter. Go to Source Since sending the first human into space in the 1960s, the solution to one key challenge has remained elusive: the efficient and reliable production of oxygen in space. On the International Space Station, this problem is addressed by heavy and energy-intensive systems that are not ideal for long-duration space missions. Go to Source […] |
