Abstract Tropical ocean evaporation is the dominant source of moisture for global precipitation. However, the dependence of evaporation‐temperature sensitivity on ocean surface radiative properties has not been quantified in the fully coupled modeling framework.

We present an analysis of the effects of spectral resolution and aperture scale on derived galaxy properties using far-ultraviolet (FUV) spectra of local star-forming galaxies from the International Ultraviolet Explorer ( R ∼ 250, field of view (FOV ...

Twisted ReSe2/α−MoO3 van der Waals heterostructures pave the way towards next‐generation polarization nanophotonic applications, where combining two biaxial layers—a triclinic source of linearly polarized emission and an orthorhombic polarization‐conversion slab—establishes a practical route for fully integrated on‐chip all‐van der Waals polarization ...

C+ 133.5 nm Emission Mechanisms on Mars Revealed by the MAVEN Observations
C ^+ emission is generated by electron impact, dissociative ionization, photoionization, and resonant scattering with carbon-related atoms, molecules, and ions in the Martian ionosphere and thermosphere. The contribution of each mechanism to the emission,

Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...

HWO Target Stars and Systems: A Survey of Archival UV and X-Ray Data
We assess archival high-energy data for key stars on the Habitable Worlds Observatory (HWO) Target Stars and Systems 2025 list, as stellar radiation is critical to shaping and interpreting planetary atmospheres.

Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Amateur Astronomy and Astronomy Education in India
In India, astronomy has been studied from the beginning of civilization. The word amateur means involvement in work for pleasure rather than as a profession. So, amateur astronomers, in many places, prefer to be called non-professional astronomers.

Excess Ultraviolet Emission at High Galactic Latitudes: A New Horizons View
We present new observations of the cosmic ultraviolet background (CUVB) at high Galactic latitudes (∣ b ∣ > 40 ^∘ ), made using the Alice UV spectrograph on board the New Horizons spacecraft.
