Two Possible Orbital Histories of Phobos

The Planetary Science Journal
The two moons of Mars, Phobos and Deimos, have orbits that are close to the Martian equator, indicating their formation from a circumplanetary disk. Phobos is currently migrating toward Mars due to tidal dissipation within the planet and may be disrupted

Physically Based Real‐Time Rendering of Eclipses

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract We present a novel approach for simulating eclipses, incorporating effects of light scattering and refraction in the occluder's atmosphere. Our approach not only simulates the eclipse shadow, but also allows for watching the Sun being eclipsed by the occluder.

One schema to rule them all: How Schema.org models the world of search

Journal of the Association for Information Science and Technology, Volume 76, Issue 2, Page 460-523, February 2025.
Abstract Several industry‐specific metadata initiatives have historically facilitated structured data modeling for the web in domains such as commerce, publishing, social media, and so forth. The metadata vocabularies produced by these initiatives allow developers to “wrap” information on the web to provide machine‐readable signals for search engines ...
