An AI approach to lunar phase detection: enhancing the identification of the new crescent with astronomical data integration [PDF]

open access: yesFrontiers in Artificial Intelligence
IntroductionThe observation of the lunar crescent is significant in astronomy, cultural traditions, and religious lunar calendar determinations. However, earth-based imaging that captures all lunar phases, particularly the new crescent across multiple ...

X-ray astronomy from the lunar surface. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci
Motivated by efforts to return humanity to the Moon, three cases are reviewed for X-ray astronomy from the lunar surface: (i) facilitation of ambitious engineering designs including high-throughput telescopes, long focal length optics and X-ray interferometery; (ii) occultation studies and the gain they enable in astrometric precision; and (iii) multi ...

The lunar dust environment: concerns for Moon-based astronomy. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci
The Moon has no atmosphere, hence, it offers a unique opportunity to place telescopes on its surface for astronomical observations. It is phase-locked with Earth, and its far side remains free from ground-based interference, enabling the optimal use of radio telescopes.

Increased and varied radiation during the Sun’s encounters with cold clouds in the last 10 million years [PDF]

open access: yesScientific Reports
Recent research raises the possibility that 2–3 and 6–7 million years ago, the Sun encountered massive clouds that shrank the heliosphere —the solar cocoon protecting our solar system— exposing Earth to its interstellar environment, in agreement with ...

Contemporary Haqiqī Calculation: Analysis of Rinto Anugraha's Lunar Eclipse Calculation Methods

open access: yesJournal of Islamic Law, 2022
Classical Islamic astronomy literature that discusses eclipse calculations still uses the ḥaqiqī bi al-taqrīb method with low accuracy. In its development, Islamic astronomical literature studies the calculation of lunar eclipses with high accuracy ...

Detection of ultra high energy cosmic rays and neutrinos with lunar orbital radio telescope

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Particle cascades induced by ultra-high-energy (UHE) cosmic rays and neutrinos impacting on the lunar regolith usually radiate Cherenkov radio emissions due to the presence of excess negative charge, which is known as Askaryan effect. Several experiments
