An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
Scientists looked for ways to trigger the “build whatever normally was here” signal for cells at the site of a wound.
The conservation of energy is one of the most fundamental laws governing our reality. But in the expanding Universe, that’s just not true.
There’s a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
A new paper reveals that the Voyager 1 spacecraft detected a constant hum coming from outside our Solar System.
From hellishly hot planets to water worlds, some distant planets are like nothing in our Solar System.
Best in class: Denmark and Uruguay. Worst in class: Papua New Guinea, Venezuela, and Russia.
Which philosopher had the strongest arguments? David Hume, who raised some of the best challenges for science, ethics, and religion.
From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?
And what if both parties are skilled at mirroring each other? Will it produce a stalemate?
Scientific surprises, driven by experiment, are often how science advances. But more often than not, they’re just bad science.
There are a few possible solutions to the problem of interstellar travel, but they largely remain within the realm of science fiction.
Our own galaxy, the Milky Way, is both completely normal and absolutely remarkable in a number of ways. Here’s the story of our cosmic home.
“Hubble’s Law” is only an approximation, and breaks down when we need it most. From anywhere in the Universe, you can choose to look out at any other galaxy that’s present. […]
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
Two aspects of memory – fast updating and long lasting – are typically considered incompatible, yet the insects combined them.
They are expected to be cheaper to build and even more reliable than today’s nuclear plants.
In physics, we reduce things to their elementary, fundamental components, and build emergent things out of them. That’s not the full story.
From time-traveling billiard balls to information-destroying black holes, the world’s got plenty of puzzles that are hard to wrap your head around.
With a finite 13.8 billion years having passed since the Big Bang, there’s an edge to what we can see: the cosmic horizon. What’s it like?
The Sun, as its never been seen before.
The highest-energy particles of all come from space, not human-made colliders. When it comes to the most energetic particle collisions of all, you might think that the Large Hadron Collider […]
There are many theories of gravity out there, and many interpretations of wide binary star data. What have we really learned from it all?
The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?
Popular media often frame scientists as having a cold, sterile view of the world. That couldn’t be further from the truth.
Ari Loeb, who suggested in 2018 that the mysterious object was an alien craft, is back to discuss the evidence.
When the average person has a “theory,” they’re just guessing. But for a scientist, a theory is the pinnacle of what we can achieve.
The natural wonders of Mauritius include the spectacular sight of an underwater waterfall. Here’s the science of how it works.
