By leveraging geodetic GNSS receivers and a pre-trained decision tree algorithm, the research offers a cost-effective and efficient method to monitor and mitigate the adverse effects of scintillation on navigation accuracy.
Unlocking the secrets of Earth's planetary boundary layer (PBL), a pivotal zone influencing air quality and climate, a new study offers unprecedented insights into atmospheric thermal contrasts (TC). By scrutinizing satellite data, researchers have shed light on how the surface-to-atmosphere temperature gradient affects the detection of atmospheric pollutants.
The research team led by Dr. Hyu-Soung, Shin at the Future & Smart Construction Research Division of the KICT is currently conducting a study on microwave-sintered lunar regolith simulant bricks. This research applies sintering techniques similar to firing ceramics, raising the temperature to create solid bricks.

Un equipo de astrónomos descubrió una pareja de cuásares en fusión que bate todos los récords, ya que no sólo se trata de la más distante detectada hasta ahora, sino también del único par de este tipo que se encuentra en una de las épocas más tempranas del Universo. El hallazgo fue posible con la ayuda del poderoso instrumento GNIRS que se encuentra instalado en el telescopio de Gemini Norte, la mitad boreal del Observatorio Internacional Gemini, financiado en parte por la Fundación Nacional de Ciencias de Estados Unidos y operado por NOIRLab de NSF.

With the help of the powerful GNIRS instrument on the Gemini North telescope, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, a team of astronomers have discovered a double-record-breaking pair of quasars.

NASA’s James Webb Space Telescope has provided a new view of the Crab, including the highest-quality infrared data yet available to aid scientists as they explore the detailed structure and chemical composition of the remnant. These clues are helping to unravel the unusual way that the star exploded about 1,000 years ago.
In a breakthrough discovery that challenges the conventional understanding of cosmology, scientists at Case Western Reserve University have unearthed new evidence that could reshape our perception of the cosmos.
The small footprint and dim light of white dwarfs, remnants of stars that have burned through their fuel, may make excellent backdrops for studying planets with enough water to harbor life. The trick is spotting the shadow of a planet against a former star that has withered to a fraction of its size and finding that it’s a planet that has kept its water oceans for billions of years even after riding out the star’s explosive and violent final throes.
Researchers from DOE and NASA joined forces to use Argonne’s Theta supercomputer to produce 4 million simulated images that are being used to prepare for future observations from the Nancy Grace Roman Space Telescope and the Vera C. Rubin Observatory.
The Norwegian Academy of Science and Letters announced the 2024 Kavli Prize Laureates, recognizing groundbreaking science for the discovery and characterization of extra-solar planets and their atmospheres; foundational research integrating synthetic nanoscale materials for biomedical use; and the localization of areas in the brain specialized for face recognition and processing.
Michigan State University researchers led by Shuo Zhang, have presented new findings that will help scientists better understand the supermassive black hole at the center of the Milky Way, Sagittarius A*.
Clouds of gas in a distant galaxy are being pushed faster and faster — at more than 10,000 miles per second — out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy’s center. It’s a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.
Odysseus, a tenacious lander built by the company Intuitive Machines, almost didn't make it to the moon. But an experiment aboard the spacecraft managed to capture an image of Earth as it might look to observers on a planet far from our own.
As a new space race revs up, propelling humans back to the Moon and toward a Mars landing for the first time, mysteries remain about the unique pressures of spaceflight on humans – especially for those blasting off through new commercial space travel operations. For the first time, researchers have data on the physical and psychological impact of spaceflight on an all-civilian crew.
Astronomers have used new and archival data from Hubble to revisit one of the strangest stars in our galaxy–40 years after it burst onto the scene as an extraordinarily bright and long-lived nova.
Using data from a deep Webb survey of the early universe, a team has identified 10 times more far-off supernovae than were previously known. This study is the first significant step toward more extensive surveys of ancient supernovae with Webb.
An international team of astronomers led by the University of Vienna has deciphered the formation history of young star clusters, some of which we can see with the naked eye at night.
