Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Theoretical physics is notorious for wild ideas that seem, at first, to be nonsensical fantasies. That's where the tooth fairy comes in.
Vague predictions and post hoc revisions help astrology feel meaningful, even while it fails empirical testing.
Astronomers study our cosmic history through stellar and galactic archaeology. But we can't conduct archaeology in space. At least, not yet.
Light pollution now steals a pristine night sky from the majority of humanity. The rise of LED lighting, primarily since 2014, is to blame.
Today, in the here-and-now, a full 13.8 billion years have elapsed since the start of the hot Big Bang. But would that be true for everyone?
In physics, we reduce things to their elementary, fundamental components, and build emergent things out of them. That's not the full story.
Animal-to-human organ transplants promise a future where survival no longer depends on another person’s death.
Messier 77 is one of the largest nearby spiral galaxies, with an active, brilliant core. Here's what JWST's incomparable eyes saw inside it.
A look at what could be if we ignore the doomers and make the most of AI.

Beneath our assumptions lies the most complex, unsolved question in physics: Why does time have any direction at all?
A relatively tiny world in the Kuiper belt, just 500 km in diameter, has an atmosphere after all, joining Pluto. Here's what we know today.
The soils of "managed forests" can take decades to rebuild the carbon stocks and microbial communities found in undisturbed forests.
Only nearby objects appear to the naked eye. With telescopes of all types, especially in space, we've smashed those records many times over.
Triton is Neptune's largest moon today, but it was once the undisputed king of the Kuiper belt. Here's why the outer solar system matters.
There's a lot of room in interplanetary, interstellar, and intergalactic space, but just how low the densities go is truly mind-boggling.
Contrary to common experience, not everything needs a medium to travel through. Overcoming that assumption removes the need for an aether.
Newton's gravitational constant, G, is still known to just 3 significant figures in 2026. New measurements merely highlight our uncertainty.
In 2006, the IAU defined "planet" for the first time, excluding Pluto and all other dwarf planets. In 2026, is it now time for a change?
From within our own galaxy to behemoths billions of light-years away, supermassive black holes create jets like nothing else in the cosmos.
It takes incredible energies to accelerate masses near the speed of light. So how do the farthest galaxies speed away from us so quickly?
