In a significant step for space-based weather forecasting, China's BeiDou Navigation Satellite System (BDS) has emerged as a pivotal player. Sun Yueqiang, the director of the Key Laboratory for Space Environment Exploration at the National Space Science Center under the Chinese Academy of Sciences, and also the deputy chief designer of the Fengyun-3 satellite, recently shared insights into the s

In an era where planetary exploration increasingly relies on unmanned rovers, ensuring their safe and effective navigation across challenging extraterrestrial terrains is paramount. This is especially true in environments like Mars or the Moon, where surfaces are often covered with regolith-a fine, loose material that can significantly impair rover mobility. Addressing this challenge, researcher

The global space sector is witnessing a significant transformation, fueled by new supply and demand dynamics, disruptive innovations, and transformational business models. As reported in the recently released market report, "Software-first satellites: essential growth lever for space," this change is largely driven by the increasing importance of digital technologies. Produced jointly by ReOrbit

After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months - a phenomenon astronomers had never seen before, a Cornell-led team reports in new research published Nov. 15 in Nature. The bright, brief flashes - as short as a few minutes in duration, and as powerful as the original explosion 100 days later -

ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like structure of gas and that gas from the star is escaping to the surrounding space. Future observations with the newly demonstrated high resolution are expected to elucidate, not only the end of a star's l

Astronomers are baffled by a mysterious and extremely bright event in the distant Universe, nicknamed the "Tasmanian Devil", which has been observed to explode repeatedly and emit more energy than hundreds of billions of stars like our Sun. The report, published in Nature, describes a Luminous Fast Blue Optical Transient (LFBOT) monitored in a new way and shown to have unusual behaviour. L

Some exoplanets seem to be losing their atmospheres and shrinking. In a new study using NASA's retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside out. Exoplanets (planets outside our solar system) come in a variety of sizes, from small, rocky planets to colossal gas giants. In the midd

Scientists are following neon signs in a search for clues to one planetary system's future and the past of another - our own solar system. Following up on a peculiar reading by NASA's previous infrared flagship observatory, the now-retired Spitzer Space Telescope, the agency's James Webb Space Telescope detected distinct traces of the element neon in the dusty disk surrounding the young Sun-like
