Gravitational wave detectors complete two year campaign with record signal count
Wednesday, 19 November 2025 06:16
The LIGO, Virgo, and KAGRA collaborations have finished their fourth observation campaign, known as O4, marking the longest and most comprehensive period of coordinated gravitational wave monitoring to date. Initiated in May 2023 and spanning more than two years, the campaign involved simultaneous data analysis and resulted in the detection of 250 new gravitational signals, which account for mor Kepler sets January launch for optical data relay satellites to expand in-orbit connectivity
Wednesday, 19 November 2025 06:16
Kepler Communications has scheduled the launch of ten 300-kilogram-class satellites in January 2026, marking the operational rollout of its optical data relay constellation. The launch will use a SpaceX Falcon 9 from Vandenberg Space Force Base, California. Each satellite will carry a minimum of four optical terminals that enable high-throughput laser links for space, air, and ground data transm Machine learning tool distinguishes signs of life from non-living compounds in space samples

Researchers developed LifeTracer, a machine learning framework, to analyze mass spectrometry data from space and terrestrial samples. They used advanced two-dimensional gas chromatography and high-resolution time-of-flight mass spectrometry to study eight carbonaceous meteorites and ten terrestrial rock samples. LifeTracer applies logistic regression to compound-level features and achieved 87 pe Ancient 'animal GPS system' identified in magnetic fossils
Wednesday, 19 November 2025 06:16
The earliest evidence of an internal 'GPS' system in an animal has been identified by researchers, which could help explain how modern birds and fish evolved the ability to use the Earth's magnetic field to navigate long distances.
The tiny magnetic fossils - dating from 97 million years ago - were buried in ancient seafloor sediments, left behind by a mysterious, unidentified organism. Power grid agreement to supply energy for Loft Orbital satellites
Wednesday, 19 November 2025 06:16
Loft Orbital and Star Catcher Industries have signed what is described as one of the first commercial energy purchase agreements for space operations. The deal allows Loft to buy power from Star Catcher's planned orbital energy grid to support its mission-agnostic satellite platforms in low Earth orbit, enabling dynamic growth in their satellite constellations.
