The cold case of S0 galaxies: quiet passing or violent death?
Today’s paper looks at two types of lenticular galaxies — seemingly alike, they took very different evolutionary paths.

Dynamic Desorption: A Tale of Cosmic Rays
Most large molecules form in the ice layers of dust grains, but we often observe these molecules in the gas phase. Today’s paper explores how cosmic rays can ‘knock’ molecules from the ice to the gas, a process known as desorption.
Bio-Signatures With Flare
Stars are known to experience burst of energy, known as flares. But what happens to biological molecules in the atmospheres of planets when a flare occurs? Today’s paper answers that by adding a bit of “flare” to exoplanets.
Glimpsing Dark Objects with Gaia
Today’s authors work out a full orbital solution for a binary microlensing system, indicating the method’s potential to probe the mass distribution of dark objects.
Searching for Multi-AGN Mergers
In today’s bite, Keir reports on a search for multi-AGN systems. How prevalent are they? And what can they tell us about black hole mergers?
