Early, Energetic Collisions Could Have Fueled Venus Volcanism: Study

By News Staff July 20, 2023

New research shows that long-lived volcanism, driven by early, energetic collisions on Venus, offers an explanation of its young surface age with stagnant-lid tectonics. This volcanic activity is fuelled by…

Auroral Mechanisms May Be Universal throughout Our Solar System

By News Staff July 18, 2023

An analysis of data obtained during the ESA/JAXA BepiColombo spacecraft’s first Mercury flyby reveals that Mercury’s southern magnetosphere aurorae are similar to those seen on Earth and Mars. An artist’s…

Tiny Fragments of Interstellar Meteor May Have Been Found in Pacific Ocean

By Natali Anderson July 10, 2023

Harvard University’s Professor Avi Loeb and colleagues have discovered at least 50 tiny spherical iron fragments near the fireball path of the first recognized interstellar meteor, IM1. Tiny meteoritic spherules…

Planetary Scientists Find Large Granite Formation on Moon’s Far Side

By News Staff July 5, 2023

The 50-km-diameter granitic system discovered below the far side feature known as Compton-Belkovich Volcanic Complex likely was formed from the cooling of molten lava that fed a volcano or volcanoes…

Martian Gullies Could Have Been Formed by On-And-Off Periods of Liquid Meltwater

By News Staff July 4, 2023

Some steep slopes on Mars have gullies with morphologies suggesting that they were formed by a liquid. However, the planet’s current climate is not conducive to the melting of water…
