In a study published in Physical Review Letters, the LIGO - Virgo - KAGRA Collaboration reported its clearest gravitational wave signal yet from a black hole merger, offering the most precise confirmation to date of Stephen Hawking's area theorem. The signal, designated GW250114, was recorded in early 2025 during LIGO's latest observing run, using detectors nearly four times as sensitive as thos

Scientists using NASA's James Webb Space Telescope are focusing on TRAPPIST-1 e, one of seven Earth-sized planets orbiting a nearby red dwarf star. Early results suggest the planet likely lost its original hydrogen-helium atmosphere, but possibilities remain for a secondary atmosphere that could sustain liquid water under the right conditions. TRAPPIST-1 e lies in its star's habitable zone

Scientists face a daunting task when trying to describe the cosmic web, the immense 3D structure of galaxies, clusters, superclusters, filaments, and voids that spans the Universe. Models like the Effective Field Theory of Large-Scale Structure (EFTofLSS) combine theory and astronomical data to make statistical predictions, but they require enormous computing power. To meet the challenge p

Dark energy - the term used to describe whatever is causing the universe to expand at an increasing rate - is one of the universe's greatest mysteries. The widely accepted theory at the present moment suggests that dark energy is constant, with the energy of empty space driving cosmic acceleration. However, last year, findings from the Dark Energy Survey (DES) and Dark Energy Spectroscopic Instr

The demonstration, targeted for 2026, will attempt to showcase a spacecraft’s ability to approach, image and maneuver around other objects in orbit without direct human control

PARIS, France – Axiom Space and Spacebilt announced plans Sept. 16 to deliver a data center node with optical communications links to the International Space Station in 2027.

The European Space Agency (ESA) and Honeywell move to the next phase of a project that will provide satellite-based quantum key distribution. The project, called QKDSat, will enable protection of critical infrastructures, such as power plants, water management systems, hospitals and banks from cyberattacks.

Viasat and Space42 have agreed to combine geostationary Mobile Satellite Services resources, aiming to create the world’s largest coordinated spectrum block for direct-to-device services within three years.

The deal underscores NGA’s push to fold commercial satellite data and artificial intelligence into U.S.
