In Earth history, a few episodes stand out for their extreme cold, when geologic evidence indicates that ice covered the planet from pole to pole during so-called Snowball Earth events. These episodes represent some of the coldest conditions the planet has ever experienced, with the entire surface essentially below the freezing point of water. Scientists link the onset and end of these global gl

AST SpaceMobile has secured a prime contract worth about 30 million dollars with the United States Space Development Agency for the Europa Track 2 Commercial Solutions program under the Hybrid Acquisition for proliferated Low Earth Orbit, or HALO, initiative. The agreement calls for AST SpaceMobile to use its BlueBird low Earth orbit satellite constellation to demonstrate resilient, low la

New observations of Jupiter's largest moon, Ganymede, reveal that its auroras share detailed structural similarities with auroras on Earth, suggesting that the physical processes that generate these lights may be universal across different types of celestial bodies. A team from the Laboratory of Atmospheric and Planetary Physics (LPAP) at the University of Liege has used NASA's Juno spacec

That the universe is expanding has been known for almost a century, but its exact rate of expansion remains one of cosmology's most hotly debated questions. A team from the Technical University of Munich (TUM), Ludwig Maximilians University (LMU) and the Max Planck Institutes for Astrophysics (MPA) and for Extraterrestrial Physics (MPE) has now imaged and modelled an exceptionally rare supernova

With launch planned for later this year, testing is well underway to ensure the MetOp Second Generation-B1 weather satellite is ready for its life in orbit around Earth. These checks include verifying that its spectacular four-panel, 11-metre-long, solar wing will deploy correctly.

From adding timestamps to banking transactions to mapping the best route to a destination, satellite navigation plays a significant role in daily life. At the same time, attempts to interfere with and fake navigation signals are increasing. For the last seven months, a new verification service for Galileo has mitigated the threat of spoofing in the Open Service by confirming that the satellite navigation data used for positioning originated in the Galileo system.

TotalEnergies faces cutting back oil and gas production if NGOs prevail in a trial that began Thursday over accusations the French energy giant failed to properly consider environmental risks. The case, brought by several NGOs and the city of Paris, is based upon a 2017 law that imposed a "duty of vigilance" on large companies. The law seeks to counter companies offloading responsibility

New Delhi (AFP) Feb 20, 2026
Fledgling Indian artificial intelligence companies showcased homegrown technologies this week at a major summit in New Delhi, underpinning big dreams of becoming a global AI power. But analysts said the country was unlikely to have a "DeepSeek moment" - the sort of boom China had last year with a high-performance, low-cost chatbot - any time soon. Still, building custom AI tools could
