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 ...

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 644-663, April 2026.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

RETRACTED ARTICLE: A Tunguska sized airburst destroyed Tall el-Hammam a Middle Bronze Age city in the Jordan Valley near the Dead Sea

Scientific Reports, 2021
We present evidence that in ~ 1650 BCE (~ 3600 years ago), a cosmic airburst destroyed Tall el-Hammam, a Middle-Bronze-Age city in the southern Jordan Valley northeast of the Dead Sea.

New Zealand's Second Meteorite: Makarewa (find, L4, S5, W2)

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
One of the most remarkable discoveries of a meteorite in New Zealand was that of Makarewa. Discovered in 1879, Makarewa is a ‘find’ that was uncovered a metre below the surface of a clay bank during excavation works for a train line in the southern South Island.

Magnetic Reversals During the Deccan Volcanism: Paleomagnetic Insights From the Pachmarhi Dykes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The three main dyke swarms that are linked to the Deccan Continental Flood Basalts are the Nasik‐Pune, Western Coastal, and Narmada‐Satpura‐Tapi (N‐S‐T) swarms. Encompassing approximately 244 mapped basaltic dykes, mainly trending E‐W and positioned along an ancient tectonic zone, the Pachmarhi dyke swarm is situated in the eastern N‐S‐T ...
