Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Reference frames and astronomy teaching: the development of a topocentric approach to the lunar phases

open access: yesScience Education International, 2019
Research related to the teaching and learning of the lunar phases reveals a low level of understanding of this astronomical phenomenon by most students of all educational levels. Therefore, there is a need to develop didactic materials to promote adequate comprehension of this phenomenon and which have been tried out in the classroom. Presented here is

Overview of lunar-based astronomy

open access: yes, 1988
The opportunities along with the advantages and disadvantages of the Moon for astronomical observatories are carefully and methodically considered. Taking a relatively unbiased approach, it was concluded that lunar observatories will clearly be a major ...

Lunar Crustal Formation by Melt Migration and Differentiation Within a Stagnant Lid

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The lunar anorthosite highlands represent the Moon's primary crust, which formed during the solidification of a magma ocean following the Moon‐forming giant impact. However, the canonical model of anorthite flotation in the crystallizing magma ocean often struggles to reproduce the long > ${ >} $200 Myr solidification timescale required by the

Profiling the turbulent atmosphere and novel correction techniques for imaging and photometry in astronomy [PDF]

open access: yes, 2010
The turbulent atmosphere has two detrimental effects in astronomy. The phase aberration induced by the turbulence broaden the point spread function (PSF) and limits the resolution for imaging.

New Astronomy in Service of Old Astrology: Close Planetary Conjunctions in Pre-Modern China

open access: yes, 2019
This article introduces various definitions and criteria for the astronomical phenomena of "encroachments" (close lunar and planetary conjunctions) in pre-modern China.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

The role of eclipses and european observers in the development of ‘modern astronomy’ in Thailand

open access: yes, 2019
‘Modern astronomy’ was introduced to Siam (present-day Thailand) (Siam officially changed its name to Thailand in 1939) when the Belgian Jesuit missionary-astronomer Father Antoine Thomas carried out stellar and lunar eclipse observations during 1681 and

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.
