Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Dust is ubiquitous in the modern Universe, appearing in nearly all galaxies. But our cosmos was born dust-free. So where does it originate?
In revolutionary Russia, a group of forward-thinking philosophers offered an alternative to both futurism and communism.
Strengthen your focus like a muscle.
It's the origin of our entire observable Universe, but it's still not the very beginning of everything.
Real understanding, argues Jeff DeGraff, doesn’t come from outputs — it comes from practice.
The most common type of exoplanet is neither Earth-sized nor Neptune-sized, but in between. Could these haze-rich worlds house alien life?
In this excerpt from "Facing Infinity," Jonas Enander examines how John Michell conceived of "dark stars," or massive bodies with enough gravity to trap light, all the way back in 1783.
The Holy Grail of physics is a Theory of Everything: where a single equation describes the whole Universe. But maybe there simply isn't one?
JWST isn't the first telescope to peer into this factory of star-birth some 5500 light-years away, but its views are the most educational.
Going back to 1990, we hadn't even found one planet outside of our Solar System. As we close in on 6000, we now see many of them directly.
Since even before Einstein, physicists have sought a theory of everything to explain the Universe. Can positive geometry lead us there?

"We're stuck at type zero. But what would it take to move between universes? What would it take to enter a black hole? What would it take to break the light barrier?"
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
The Juno spacecraft, orbiting and imaging Jupiter since 2016, is still succeeding. Without a further extension, the mission now faces death.
The African Union argues that the Mercator projection distorts the continent, both in size and global attention.
With several seemingly incompatible observations, cosmology faces many puzzles. Could early, supermassive stars be the unified solution?
As we look to larger cosmic scales, we get a broader view of the expansive cosmic forest, eventually revealing the grandest views of all.
Explanations for the cosmic speed limit often conflate mass with inertia.

“Nothing about human behavior makes sense except in the light of culture and in anthropology, and we need to understand the cultural component to our behaviors as well.”
The Universe isn't just expanding; the expansion is accelerating. If different methods yield incompatible results, is dark energy evolving?
