Earth and Space Science, Volume 12, Issue 8, August 2025.Abstract This study presents a validated design of a dual‐band wireless relay system of “pucks” for through‐ice communication between a cryobot and a surface lander during a future exploration of the Europan cryosphere. The design of a terrestrial demonstration system and the results of a 103 m through‐ice system test in a relevant environment near ...

Using synthetic emission maps to constrain the structure of the Milky Way
, 2013 We present the current standing of an investigation into the structure of the Milky Way. We use smoothed particle hydrodynamics (SPH) to simulate the ISM gas in the Milky Way under the effect of a number of different gravitational potentials representing

Spiral Galaxies as Enantiomers: Chirality, an Underlying Feature in Chemistry and Astrophysics
, 2005 Spiral galaxies are axi-symmetric objects showing 2D-chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in aminoacids ...

Plasticity of the heart in response to changes in physical activity
The Journal of Physiology, Volume 603, Issue 13, Page 3665-3677, 1 July 2025.Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

On the Spiral Structure of the Milky Way Galaxy
, 2010 We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e.

Density waves and star formation in grand design spirals
, 2013 HII regions in the arms of spiral galaxies are indicators of recent star-forming processes. They may have been caused by the passage of the density wave or simply created by other means near the arms.
