Journal of Astronomy and Sharia Applications (JASA) is an international peer-reviewed applied astronomy journal with a distinctive focus on the application of astronomical science within sharia, Islamic law, and Islamic religious practices. The journal advances scientifically rigorous and internationally relevant research in observational, computational, geospatial, atmospheric, historical, and applied astronomy.

JASA positions astronomy as its primary scientific discipline, while sharia, Islamic law, and Islamic religious practices constitute distinctive domains of application, interpretation, and interdisciplinary inquiry. The journal particularly welcomes studies in which astronomical phenomena, data, methods, technologies, or models form the principal analytical framework.

Observational and theoretical studies of lunar crescent visibility, new-moon detection, Hijri calendar systems, visibility criteria, lunar ephemerides, calendar modelling, and comparative or international approaches to Islamic calendrical unification.

Research involving telescopes, observatories, astronomical imaging, photometry, CCD/CMOS detectors, optical systems, digital instrumentation, observational techniques, and technological innovation for astronomical observation.

Astronomical computation, numerical modelling, ephemeris calculation, astronomical software, artificial intelligence, machine learning, image processing, computer vision, data science, and digital technologies applied to astronomical problems relevant to Islamic religious practices.

Studies on solar altitude, twilight, dawn and dusk phenomena, solar position, atmospheric effects, high-latitude prayer times, computational methods, and comparative standards for determining Islamic prayer times.

Research on qibla determination using spherical astronomy, geodesy, GIS, GNSS, satellite positioning, cartography, spatial analysis, remote sensing, and other geospatial technologies.

Studies of atmospheric extinction, sky brightness, twilight luminosity, atmospheric refraction, cloud and aerosol effects, light pollution, dark-sky quality, observational environments, and environmental factors affecting astronomical observations.

Interdisciplinary studies examining the use of astronomical data and scientific evidence in fiqh, fatwa, Islamic legal reasoning, religious authority, maqasid al-shariah, and the formulation or implementation of Islamic religious practices.

Research on solar and lunar eclipses and other astronomical phenomena, including their observation, prediction, computation, historical interpretation, and relevance to Islamic religious practices.

Studies of astronomical manuscripts, classical astronomical tables, observatories, instruments, Muslim astronomers, mathematical astronomy, scientific transmission, and the historical development of astronomy in Muslim societies.

Research on astronomy education, Islamic astronomy curricula, astronomical literacy, citizen astronomy, observatory-based learning, science communication, international research collaboration, and comparative astronomical practices across countries and regions.

JASA gives priority to manuscripts that demonstrate clear astronomical significance, methodological rigor, reproducible or verifiable evidence, international relevance, interdisciplinary contribution, and strong engagement with current scholarly literature.

Purely theological, jurisprudential, historical, educational, or social studies that do not contain a substantive connection to astronomy or astronomical applications fall outside the journal's primary scope.
