A recurring cloud over the Martian volcano Arsia Mons turns out to freeze straight out of water vapour, with no dust grain to seed it, a process never before caught in any planetary atmosphere. We also look at the first interstellar detection of fully deuterated methanol by ALMA, a white dwarf that may be feeding on a planet born after its star died, and three quiet dwarf galaxies near M101 found in public archive data by a first year undergraduate.

In 2013, NASA's Curiosity rover detected organic compounds in Martian rock samples, prompting further investigation into their implications for the planet's history.

Cosmological models are largely settled on the structure of the very early universe which, moments after the big bang, could be modelled as a smooth, homogeneous fluid.

The James Webb space telescope (JWST) continues to provide astounding insights into the nature of exoplanets as it completes part of the Transiting Exoplanet Early Release Science Program with the goal of compiling the fu
