- Astronauts' Vision Problems Linked to Prolonged Space Exposure, Posing Risks for Mars Missions يناير 28, 2025Extended space missions, such as those aboard the International Space Station (ISS), are linked to significant ocular changes in astronauts. These changes, collectively termed spaceflight-associated neuro-ocular syndrome (SANS), affect around 70 percent of astronauts. A recent study found reductions in ocular rigidity, intraocular pressure, and ocular pulse amplitude,...
- Astronomers Capture Supermassive Black Hole Plasma Jets at Birth يناير 28, 2025For the first time, plasma jets from a supermassive black hole have been observed in real time. Located 270 million light-years away in galaxy 1ES 1927+654, the jets traveled at one-third the speed of light. Emerging in 2024 after a radio flare in 2023, the jets broke through dense gas near the black hole, which […]
- NASA's Dual Rocket Launch to Uncover Mysteries of Alaska's Auroras يناير 28, 2025NASA is set to launch two rockets from the Poker Flat Research Range in Alaska, aiming to study the aurora borealis. The missions will focus on flickering auroras and the mysterious dark patches known as "black auroras." Led by Marilia Samara and Robert Michell, the rockets will collect data on auroral behaviour and electron movement. […]
- Invisible Boson Stars Could Hold the Key to Dark Matter's Mysteries يناير 28, 2025Boson stars, invisible celestial objects theorised to form from axions, are now at the centre of dark matter research. Axions, light and wave-like bosons, may cluster under gravity, forming these mysterious entities. Unlike normal stars, boson stars neither emit light nor interact with regular matter in observable ways. With sizes ranging from small stellar masses […]
- SpaceX Falcon 9 Deploys 21 Starlink Satellites, Enhancing Mobile Connectivity يناير 28, 2025SpaceX launched 21 Starlink satellites into low Earth orbit from Cape Canaveral on January 27, 2025, at 5:05 p.m. EST. Among these, 13 satellites feature Direct-to-Cell technology designed to enhance mobile connectivity. The Falcon 9 rocket used for the mission was powered by a first-stage booster completing its 20th successful flight. This booster landed on […]
- New Laser Imaging Technique Unlocks Nanoscale Heat and Charge Transport in Diamond يناير 28, 2025Researchers have developed a laser-based imaging technique that uses deep-ultraviolet light to study heat and charge transport in ultrawide-bandgap semiconductors, such as diamond. This breakthrough overcomes limitations of traditional visible-light imaging, enabling nanoscale resolution of transport behaviors in diamond. The technique could revolutionise the design o...
- Storm Éowyn Hits UK and Ireland: Red Alerts for Snow, Wind, and Flooding يناير 28, 2025Storm Éowyn, a rapidly intensifying bomb cyclone, is set to hit the UK and Ireland, bringing snow, heavy rainfall, and winds up to 160 km/h. Red weather warnings have been issued for multiple regions, including Ireland, Northern Ireland, and parts of Scotland, signaling life-threatening conditions. Meteorologists are comparing its strength to the devastating Storm Eu...
- SpaceX Falcon 9 Launches 23 Starlink Satellites, Sets Booster Record يناير 28, 2025SpaceX launched 23 Starlink satellites on January 24, 2025, from Vandenberg Space Force Base, marking its 11th Falcon 9 mission of the year. The booster achieved its record 23rd flight and successfully landed on the drone ship "Of Course I Still Love You" in the Pacific Ocean, bringing SpaceX's total orbital-class booster recoveries to 401. […]
- ISRO to Launch 100th Satellite NVS-02 Boosting India's NavIC System يناير 28, 2025ISRO will launch its 100th satellite, NVS-02, on January 29 from Sriharikota using the GSLV-F15 rocket. Part of the Navigation with Indian Constellation (NavIC) system, the satellite enhances precise Position, Velocity, and Timing services for India and nearby regions. Weighing 2,250 kg, it features advanced navigation payloads and indigenous atomic clocks for improve...
- Asteroid 2024 PT5 Linked to Lunar Surface, Reveals Planetary Defense Insights يناير 28, 2025Asteroid 2024 PT5, sized like a school bus, passed Earth in January at 1.1 million miles. Research suggests it originated from the moon, ejected thousands of years ago by an impact. Spectral analysis matched it to Apollo 14 lunar rocks, ruling out artificial origins. This is the second known lunar asteroid after 469219 Kamo’oalewa. The […]
