The Past and Present State of Astronomy Education in Thailand

, 1990
About 300 years ago in Lopburi and Ayudhaya, many astronomical observatories were designed, constructed, and supported by the Roman Catholic missionaries from Europe and by King Narai the Great of Siam (Thailand). The interesting recorded history of Thai

Long‐Lived Equatorial Plasma Bubbles Persisting Into the Afternoon Over the Pacific Sector During the Recovery Phase of the April 2023 Geomagnetic Storm

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Equatorial plasma bubbles (EPBs) are typically nighttime ionospheric irregularities, and their persistence into daytime sectors remains insufficiently understood. Here, we investigate long‐lived EPB‐related plasma depletion structures over the Pacific sector during the recovery phase of the 23–25 April 2023 geomagnetic storm using Formosa ...

Post‐Sunset Merging of Equatorial Ionization Anomaly Crests Into a Single Peak Over ∼35° Longitude During the 19 January 2026 Geomagnetic Superstorm

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We investigate the nighttime equatorial ionosphere during the 19 January 2026 geomagnetic storm using Global‐scale Observations of the Limb and Disk OI 135.6 nm observations and ground‐based GPS Total Electron Content. The observations reveal a pronounced longitudinal asymmetry in the post‐sunset equatorial ionization anomaly (EIA).

Hybrid Plasmonic Photoanodes for Effective Photocatalytic Water Splitting

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
Photocatalytic water and seawater splitting with high efficiency (∼10%) by hybrid plasmonic photoanodes based on a metamaterial made of metal nanostructures. ABSTRACT Photocatalytic water splitting by semiconductors is elucidated in many important works.

Temperature Dependent Complex Refractive Index (CRI) of Hexagonal Ice in the Range 150–270 K: Infrared and Far‐Infrared Transmission Measurements at the AILES Beamline

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The complex refractive index (CRI) of ice is one of the main parameters driving the optical properties of ice clouds and frozen surfaces, hence their climate impact. While already characterized at short wavelengths, ice CRI has never been measured across the infrared range at temperatures relevant to Earth.
