Do Galaxies Really Glow in Sync — or Are We Just Tilting Our Heads?
When galaxies are viewed from far away, their radio, infrared, and gamma-ray emissions line up in tight correlations long taken as proof that cosmic rays dump all their energy before escaping. New modeling argues this tightness is mostly a trick of geometry and viewing angle, not evidence of cosmic-ray calorimetry at all.
A Swift recovery: Why NASA’s Swift X-ray observatory is getting an orbital boost
A rescue mission is underway to save the Swift X-ray observatory! Today’s bite takes a look at how this will work and why Swift deserves a second life.
SPHEREx: the niftiest space telescope you may not have heard of
NASA’s SPHEREx mission is collecting an infrared spectrum for every point in the sky. That data set could revolutionize our understanding of cosmic inflation, galaxy formation, and how ices drive planet formation and surface chemistry.
The Protoplanetary Mid-life Crisis
What happens when protoplanetary disc systems stop following the rules? Today’s paper looks at how some stars with protoplanetary discs in the Upper Scorpius Region experience a mid-life crisis and behave unexpectedly.
Telling Aliens from Weird Chemistry on Ocean Planets
A spacecraft mission to Saturn’s moon Enceladus found unexpectedly high methane in its ice plumes, fueling speculation about life in its hidden ocean. A new Nature Astronomy sutdy shows current models can’t reliably distinguish that methane from purely non-biological sources. The one signal that could tell life apart from chemistry, a molecular “handedness” pattern, would likely be destroyed before we could ever detect it.
Guest: Brown Dwarf Companion Throws a Wrench into Hot Jupiter Formation
Astronomers thought “hot Jupiter” exoplanets formed far from their stars before migrating inwards to an ultra-close orbit. Today’s paper challenges that assumption, presenting evidence that one hot Jupiter formed close to its star.

Why messing up my crocheting makes me a better scientist
It’s easy to be self-critical and fall into the trap of perfectionism, but mistakes are how we learn and discover new things. Embrace imperfection!
What is life, really? A case for interdisciplinary science
We’re trying to find life beyond Earth… but we still can’t fully agree on what life actually means. Astronomers, chemists, and biologists all approach it from different angles and they don’t always speak the same scientific language. So what happens when you try to solve one of science’s biggest questions in a very multilingual group chat? Keep reading if you want to join the conversation.
