Scientists are calling attention to an extremely common health problem that’s been making astronauts uncomfortable: sinus issues. Researchers from Houston Methodist hospital’s Department of Otolaryngology – Head and Neck Surgery reported the results of their recent study that probed whether astronauts experience sinonasal issues, which include common symptoms such as nasal congestion and pressure or pain in the face, while …

On July 3, 2025, NASA astronaut Nichole Ayers, aboard the International Space Station (ISS), captured a fleeting but scientifically valuable image of a gigantic jet—a rare atmospheric electrical discharge that shoots from thunderstorm tops into the edge of space. This event, reported on NASA’s official portal, not only offered stunning visuals but also a critical data point for understanding the …

An object that came from outside our solar system is hurtling towards the sun at roughly 61km (38 miles) a second. First detected in July, this visitor from outer space – known as 3I/Atlas – is only the third known interstellar object to have been observed, after ‘Oumuamua in 2017 and 2I/Borisov in 2019. Excitement has been growing since the …

Astronomers using NASA’s James Webb Space Telescope have discovered a newfound moon orbiting icy Uranus, the seventh planet from the sun. The moon, known as S/2025 U1, is just 6 miles (10 kilometers) or so in diameter, which made it invisible to NASA’s Voyager 2 probe during its 1986 flyby of the planet, as well as rendering it undetectable by …

Free-floating, planetary-mass objects that are just drifting carefree through the galaxy, untethered and starless, appear to be able to generate their own systems of moons, like a planetary system on a miniature scale. An analysis of new JWST observations on a number of rogue planets – each weighing between five and 10 Jupiters – has revealed the presence of disks …

A US military space-plane, the X-37B orbital test vehicle, is due to embark on its eighth flight into space on August 21, 2025. Much of what the X-37B does in space is secret. But it serves partly as a platform for cutting-edge experiments. One of these experiments is a potential alternative to GPS that makes use of quantum science as …

IN A NUTSHELL 🚀 Venus Aerospace’s test of the Rotating Detonation Rocket Engine marks a breakthrough in propulsion technology. 💥 The engine uses supersonic explosions for thrust, offering greater efficiency and thrust-to-weight ratios. 🌐 The combination with the VDR2 air-breathing ramjet could enable hypersonic vehicles to operate like conventional aircraft. ✈️ The advancements aim to make high-speed travel more accessible …

A recent study from the University of Nottingham has unveiled groundbreaking research into fuel-free spacecraft propulsion systems, providing hope for more sustainable space exploration. The study, titled “Modeling and Numerical Optimization of Refractive Surface Patterns for Transmissive Solar Sails,” published in Acta Astronautica, explores a cutting-edge approach to spacecraft propulsion that doesn’t rely on traditional fuel-based methods. By harnessing sunlight …
