In Situ Carbonation of Sedimentary and Igneous Rocks of Ultramafic Composition in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Over 3.5 years of exploration in Jezero Crater, the Perseverance rover has explored several geological units of diverse origins and natures, performing multi‐technique remote analyses of the chemistry and mineralogy of rocks with the SuperCam instrument suite.

Illumination Model of Lunar Terrain around Lunar Laser Retroreflectors Based on LOLA Data

Remote Sensing
Lunar laser retroreflectors are a crucial target for lunar laser ranging (LLR). During LLR operations at all lunar laser ranging stations, the considerable distance between the Earth and the Moon makes it impossible to visually identify the position of ...

Gravitational wave astronomy with radio galaxy surveys

, 2016
In the next decade, new astrophysical instruments will deliver the first large-scale maps of gravitational waves and radio sources. Therefore, it is timely to investigate the possibility to combine them to provide new and complementary ways to study the ...

Thermal Evolution of the Sulfur‐Rich, Small Terrestrial Planetary Core as Inferred From the Experimental Study of the Fe‐S‐O‐H System

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The cores of rocky planets, including the Earth, are believed to contain light elements such as silicon, oxygen, sulfur, hydrogen, and carbon. Amongst them, sulfur appears to be rich in the cores of small terrestrial bodies like Mars and Ganymede. To understand the evolution of sulfur‐rich cores in the presence of other light elements, we have

3D Localization of FRB 20190425A for Its Potential Host Galaxy and Implications

The Astrophysical Journal
Fast radio bursts (FRBs) are high-energy, short-duration phenomena in radio astronomy. Identifying their host galaxies can provide insights into their mysterious origins. In this paper, we introduce a novel approach to identifying potential host galaxies

A Panspermia Origin for Venus Cloud Life

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Decades of study have hinted at the astrobiological potential of Venus's cloud layers. This potential is often cast as stemming from the idea that the Venusian surface was clement in the past. As the climate changed, life then remained in, or perhaps evolved and migrated to, the last habitable niche: the altitudes above ∼50 km with Earth‐like ...

Dealing with data gaps for TianQin with massive black hole binary signal

European Physical Journal C: Particles and Fields
Space-borne gravitational wave detectors like TianQin might encounter data gaps due to factors like micro-meteoroid collisions or hardware failures. Such events will cause discontinuity in the data, presenting challenges to the data analysis for TianQin,

Gravitational Waves Astronomy: a cornerstone for gravitational theories

, 2010
Realizing a gravitational wave (GW) astronomy in next years is a great challenge for the scientific community. By giving a significant amount of new information, GWs will be a cornerstone for a better understanding of gravitational physics. In this paper

The Efficient Delivery of Highly Siderophile Elements to the Core Creates a Mass Accretion Catastrophe for the Earth

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a “late veneer” of impacts after the giant impact phase of planet formation. Estimates for total mass accretion during this period typically assume all HSEs delivered remain entrained in the mantle.
