X-ray astronomy from the lunar surface [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2023 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 ...

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

The Second Lunar Anomaly in Ancient Indian Astronomy [PDF]
Archive for History of Exact Sciences, 2006 All early Indian lunar models, from about A.D. 450 – 650, used only one anomaly – the variation in speed of the Moon as it circles the zodiac. Unlike the Hipparchan model, which treated the same anomaly in terms of a single epicycle or its equivalent eccentric deferent, the Indian lunar (and solar) models without exception used the concentric equant ...

The lunar dust environment: concerns for Moon-based astronomy. [PDF]
Philos Trans A Math Phys Eng SciThe 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]
Scientific ReportsRecent 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 ...

Visual Lunar and Planetary Astronomy [PDF]
, 2013 With the advent of CCDs and webcams, the focus of amateur astronomy has to some extent shifted from science to art. The object of many amateur astronomers is now to produce “stunning images” that, although beautiful, are not intended to have scientific ...

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