Emperor penguins show dramatic decline in one region of Antarctica, satellite photos show
WASHINGTON — The population of emperor penguins in one part of Antarctica appears to be declining faster than previously thought, according to a new analysis of satellite imagery released Tuesday

Russia is targeting what's left of its capacity for innovation in space toward pestering the US military.
US intelligence officials last year said they believed Russia was pursuing a project to place a nuclear weapon in space.
The detonation of a nuclear bomb in orbit could muck up the space environment for years,
indiscriminately disabling countless satellites,
whether they're military or civilian.
Russia denied that it planned to launch a satellite w…

Unconditionally Secure Wireless-Wired Ground-Satellite-Ground Communication Networks Utilizing Classical and Quantum Noise
In this paper, we introduce the Kirchhoff-Law-Johnson-Noise (KLJN) as an approach to securing satellite communications. KLJN has the potential to revolutionize satellite communication security through its combination of simplicity, cost-effectiveness, and resilience with unconditional security. Unlike quantum key distribution (QKD), which requires complex, fragile, and expensive infrastructure like photon detectors and dedicated optical links, KLJN operates using standard electronic components …

On the Earth's tidal perturbations. II. LARES 2 satellite
Laser-ranging satellites have proved their efficiency in high precision testing of General Relativity and constraining modified gravity theories proposed to explain the dark sector and the cosmological tensions. The LARES 2 satellite launched in 2022, is currently providing improved information regarding the frame-dragging effect predicted by General Relativity, as well as the geodesy, thus essentially complementing the data of already existing laser-ranging satellites. The proper knowledge of …

Born to be Starless: Revisiting the Missing Satellite Problem
The massive Local Group galaxies both host substantially fewer satellites than the subhalos expected from the cold dark matter paradigm, and the recent investigations have highlighted the interplay between baryons and dark matter. We investigate the processes that make subhalos starless, using high-resolution cosmological simulations. We found that the number of satellites around Milky Way analogs closely aligns with observations, which accords with recent studies. In our simulations, the major…

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe,
according to new research.
Cosmologists at Durham University used a new technique combining the highest-resolution supercomputer simulations that exist,
alongside novel mathematical modeling, to predict the existence of missing "orphan" galaxies.
