A new technique developed by University of Hawaii astronomer Nader Haghighipour has successfully detected a transiting circumbinary planet in TESS data. The discovery validates the method, which reduces the time to detect such planets from over a year to just five days.
Scientists study potential for life around M-dwarf planets with new telescope, finding atmospheres may be dried out due to intense radiation. The James Webb Space Telescope can detect gases in heavy carbon dioxide or oxygen-dominated atmospheres.
Researchers have discovered a uniquely shaped hot spot on a baby star 450 million light-years away, providing new clues about the formation of our solar system. The discovery confirms accretion models and sheds light on how young stars grow.
The Dartmouth Engineering team will conduct research on planetary science relating to icy planets' geophysics and astrobiology, aiming to understand the nature of these worlds and their habitability. The project will provide valuable tools for interpreting measurements taken by future missions.
Researchers analyzed images of Mercury's surface and found only 14 boulders, compared to the Moon's 30 times more frequent presence. Factors such as micrometeorite bombardment, thicker regolith, and extreme temperature fluctuations contribute to the rarity of boulders on Mercury.
The IFSS portal offers over 100 innovative solutions to improve nutrition, restore the environment, and promote social equity. It provides a platform for collaboration and access to information about game-changing solutions.
The UN Decade of Ocean Science for Sustainable Development has an ambitious agenda to transform ocean health. The initiative provides a non-prescriptive framework for transformational action across geographies, sectors, disciplines, and generations.
Research reveals physical connectivity between southern Red Sea and Indian Ocean, highlighting need for regional marine conservation approach. Genetic patterns suggest clearer separation between northern and southern parts of sea.
A new AI-powered system, Neural Lander, uses a deep neural network to help autonomous drones land more safely and quickly, while gobbling up less power. The system has been tested and achieved significant improvements in landing accuracy, with reductions of up to 100% in vertical error and 90% in lateral drift.
Researchers at Yale and the Flatiron Institute found that compact, multiple-planet systems are more likely to form around stars with lower amounts of heavy elements. This discovery suggests new insights into the formation of smaller planets and their potential for supporting life.
A University of Texas at Arlington astrophysicist has created a new online tool called BinHab that can calculate the regions of binary systems favorable for life. The tool uses a comprehensive mathematical approach to consider both stellar radiation and gravitational influence, directly relevant to NASA's Kepler mission.
A $600,000 grant will study the effects of climate change on water quality in the Chesapeake Bay. The research team aims to clarify the implications of continued threats from agricultural lands, urban sprawl, and climate change.
A recent study by Caltech researchers found that fruit flies use their antennae to quickly sense changes in wind speed, helping them maintain a steady groundspeed. The findings suggest the antennae are responsible for initial deceleration in headwinds and provide critical information to help the fly regain its original speed.
The researchers created artificial nanoassemblies inspired by plant photosystems, which may collect and convert energy. They successfully joined individual units into larger arrays, enabling complex functional nanosystems with applications in Raman spectroscopy and catalytic processes.
A team of astronomers found that butterfly-shaped planetary nebulae are mysteriously aligned in the sky, with their long axes aligned along the plane of our galaxy. This surprising result hints at a more mysterious factor influencing the formation of these objects, possibly due to strong magnetic fields as the bulge formed.
Researchers are collecting high-tech sensing data from various sources to create a reliable early-warning system for train operators. The goal is to predict natural disasters and possible terror attacks on rail lines.
A miniscule detector developed by Merlijn Hajenius at Delft University of Technology has shown promising results for studying cosmic radiation and its impact on the universe. The detector, which uses a superconductor to detect terahertz frequencies, offers new insights into star systems and planetary birth.
The Antarctic ozone hole has broken records for area and depth, with an average area of 10.6 million square miles and a record low ozone value of 85 Dobson Units. The large ozone hole is caused by human-produced compounds releasing chlorine and bromine gases in the stratosphere.
The University of Colorado at Boulder has proposed a system to map planetary systems around other stars and detect exo-solar planets as small as Earth's moon. The New Worlds Imager concept uses a giant 'pinhole camera' in space to capture images of distant planets, including their oceans, continents, and atmospheres.
Researchers at University of Warwick develop Cybersphere, a VR system that allows users to move freely in virtual environments. The technology combines high power projectors and rotation sensors to provide a fully immersive visual experience.
Centrifugal relays use reusable ball bearings to accelerate payloads at high velocity, avoiding exponential growth in reaction mass. The system requires precise aiming and tracking, but can be controlled by monitoring velocity and direction.
Biosphere 2, a closed system that supported eight scientists for two years, offers valuable lessons for long-term space missions. The system's life support and agricultural systems will be crucial for future space travel.
