Is Mars still volcanically active?
A new study of geologically young lava flows in Elysium Planitia suggests that Mars might still have residual volcanic activity below its surface. The finding could also correlate with seismic activity detected by the InSight lander in the same region and may have implications for possible martian life.

Are There Active Volcanoes on Mars?
Mars is a dead planet — “Or is it?” asks the New York Times:
Previous research has hinted at volcanic eruptions on Mars 2.5 million years ago. But a new paper suggests an eruption occurred as recently as 53,000 years ago in a region called Cerberus Fossae, which would be the youngest known volcanic eruption on Mars. That drives home the prospect…
Mars plays shepherd to our moon’s long-lost twin, scientists find
An international team of planetary scientists led by astronomers at AOP have found an asteroid trailing behind Mars with a composition very similar to the moon’s. The asteroid could be an ancient piece of debris, dating back to the gigantic impacts that formed the moon and the other rocky planets in our solar system like Mars and the Earth. The research,…
Are there active geysers at Enceladus’ north pole?
Water-vapor geysers erupt from cracks at the south pole of Saturn’s moon Enceladus. Scientists using Cassini data now have evidence for fresh ice at the moon’s north pole, too. Could it be more geysers for this fascinating ice moon? Source: https://earthsky.org/space/fresh-ice-enceladus-north-pole-geologic-activity…
Geologic age of Finsen Crater on far side of the moon found to be 3.5 billion years
The absolute model age (AMA), or geologic age of Finsen crater on the moon’s far side is determined to be about 3.5 billion years (Ga) based on crater counting method, according to a study published in Icarus. Source: https://phys.org/news/2020-09-geologic-age-finsen-crater-side.html…
New method determines planetary regolith thermal conductivity
A new analytic model for calculating the effective thermal conductivity of planetary regolith allows scientists to better understand the connections between the physical and thermal properties of planetary surfaces and the processes that depend on them, according to Planetary Science Institute Senior Scientist Stephen E. Wood, author of “A Mechanistic Model for the Thermal Conductivity of Planetary Regolith 1: The Effects…
When the sky exploded: Remembering Tunguska
On June 30, 1908, the largest asteroid impact in recorded history occurred in remote Siberia, Russia. We now celebrate Asteroid Day each year on the anniversary the Tunguska event, as it is now known. Source: https://earthsky.org/space/what-is-the-tunguska-explosion…
