Many collaborations have used JWST to take deep-field images: some wider and some deeper than others. Here's how it can surpass them all.

A century ago, quantum physics overthrew our view of a deterministic Universe. A profound 21st century theorem closes the door even further.

"The thing that the nihilist recognizes is that the values he or she holds are not grounded in anything other than their own preferences."

The Universe formed stars, galaxies, and even galaxy clusters extremely early on in our cosmos. This new marvel is one more JWST surprise.

The Stoic philosopher argued that most of life is outside our control — but the little we do control defines who we are.

Our great hope is that today's indirect, astrophysical evidence will someday lead to successful direct detection. What if that's impossible?

Just like animals, galaxies often have bizarre, unusual, or even unique properties. But finding many, all at once, really does raise alarms.

Ernst Stromer discovered Spinosaurus in Egypt. His fossils were destroyed in WWII, yet still shape how we imagine this mysterious dinosaur today.

Our view of the world, the Universe, and ourselves can change with just one glimpse of what's out there. It's happened many times before.

Reading isn’t just writing prep; together, reading and writing help writers think and generate original ideas through extended cognition.

"The process of systematizing, correcting errors, finding approximations, and making them work as civil systems that was what really drove me to start looking at human calculation and what was the foundation that it laid for the modern computer age."

Even in an expanding Universe, we expect both redshifted and blueshifted galaxies. But nearly every one we see is redshifted. Here's why.

Today, nostalgia is somewhat kitsch. Back then, it was something to be feared.

"It's this modern idea of doing voluntary discretionary, physical activity for the sake of health and fitness."

The Sun often produces solar flares and coronal mass ejections, but a rare solar radiation storm made the 2026's first great auroral show.
