Urban environments pose unique challenges for Global Navigation Satellite Systems (GNSS), with tall buildings, vehicles, and other obstacles often disrupting signals and causing Non-Line-of-Sight (NLOS) errors. To address this, researchers have developed an Artificial Intelligence (AI)-driven solution using the Light Gradient Boosting Machine (LightGBM), offering a new level of precision in iden

Not because it is easy but because it is hard: this historic space phrase is pretty much the definition of ESA’s double-satellite Proba-3 mission, which will employ precise formation flying to produce artificial total solar eclipses in orbit, casting a shadow from one spacecraft to the other. No-one has ever flown a mission like this, up until now. So how is it going to work? Find out in this second trailer video.
Launch now scheduled for Thursday 5 December

Detonation, a supersonic combustion wave driven by shock waves and chemical energy, is a powerful means of converting chemical energy into thrust. This method has long been explored to enhance aerospace propulsion by improving thermodynamic cycle efficiency. Since the 1950s, various detonation engines, such as pulse detonation engines, oblique detonation engines, and rotating detonation engines,

Researchers have found that water on Comet 67P/Churyumov-Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have helped deliver water to Earth.

Astronomers have identified a fourth planet in the Kepler-51 system, a discovery led by researchers at Penn State and Osaka University using data from NASA's James Webb Space Telescope (JWST). The system, previously known for its three ultra-low density "super-puff" planets, gained a new dimension as the unexpected orbital behavior of Kepler-51d revealed the presence of an additional planet.

Lab-based research forms the foundation of modern scientific inquiry, but it often falls short in replicating real-world experiences. This limitation is particularly pronounced in fields like cognitive neuroscience and neuropsychology, where environmental stressors significantly impact human thought and behavior.
