What geological features on Earth can be used to better understand unique geological features on Jupiter’s icy moon, Europa? This is what a recent study published in *The Planetary Science Journal* hopes to address as a team of researchers investigated potential Earth analogs for studying a unique geological feature on Europa scientists identified almost 30 years ago. This study has the potential help scientists gain insights into Europa’s unique geological features, some of which scientists hypothesize are caused by the moon’s internal liquid water ocean.

How did life begin on Earth? Based on studies of fossilized bacteria, scientists theorize that life first emerged on Earth over 4 billion years ago as simple, single-celled organisms. Over time, these organisms evolved to incorporate photosynthesis and sexual reproduction, eventually giving rise to more complex multicellular organisms, plants, and, eventually, mammals. Despite this scientific consensus, the question of how inorganic chemicals came together to form organic molecules that gradually evolved into self-replicating systems remains unclear.

The Large and Small Magellanic Clouds are irregular dwarf galaxies and satellites of the Milky Way. The LMC is about 163,000 light-years away and the SMC is about 206,000 light-years away, and their close proximity makes them excellent laboratories for the study of galaxies in general. The Clouds are the focus of a new research group being formed at the Leibniz Institute for Astrophysics Potsdam (AIP).

How to see the best meteor shower of the year.

Imagine trying to spot a single firefly orbiting a lighthouse from hundreds of kilometres away. That's essentially the challenge astronomers face when attempting to study Proxima b, an Earth sized exoplanet orbiting Proxima Centauri, the closest star to our Solar System. The star shines 10 million times brighter than its planet, drowning out any hope of detecting the faint light reflected from that distant world. Now scientists at the University of Geneva have successfully tested key components of an instrument designed specifically to solve this seemingly impossible problem.
