Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
The newest find recovers the earliest merger in galactic history: just 2 billion years after the Big Bang. Here’s what we know today.
Recent evidence could indicate the Universe doesn't expand evenly. Does that change our expected fate: Big Rip, Big Crunch, or Heat Death?
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
Time isn't the same for everyone, even on Earth. Flying around the world gave Einstein the ultimate test. No one is immune from relativity.
We assume there's no preferred frame of reference in the Universe, and that light behaves the same in all directions. What if we're wrong?
We've now found many "conjoined" objects in the asteroid and Kuiper belts, including the first contact trinary, Nysa. What does it all mean?
On Earth's surface, we accelerate at 1g: 9.8m/s². In orbit, the acceleration is only slightly less. So why, then, are astronauts weightless?
Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn't instant.
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
Today, the world's largest operating optical telescope is 10.4 meters in diameter. These 3 facilities will lead astronomy's next generation.
The artistic and the mathematical mind are not so far apart.
With the National Solar Observatory's incredible DKIST, we see the Sun in the highest resolution ever. Its latest images blew us all away.
Few wavelengths of light reach Earth's surface; the others require going to space. What can the ultraviolet ASPERA space telescope do?
On a world map of lightning strikes, the world’s busiest sea routes glowed bright — until ships cleaned up their act.
Between war, disease, environmental destruction, and resource overconsumption, our civilization's future is uncertain. Can science save us?
As far as we can tell, there's no limit to how far it goes on; only a limit to how far we can see. Could the Universe truly be infinite?
A Cold War accident became a reliable tool for using artificial lights at night to map GDP, poverty, urban sprawl, and even illegal fishing.
The Earth is a massive planet, but doesn't form a truly perfect sphere. Here's how to understand our strongest and weakest gravity points.
Neither Vannevar Bush's "Science: the Endless Frontier" nor OSTP's "Science: A New Golden Age" got it fully right. Here's what they missed.
Obviously, the gas giants all top this list. But the fall-off is rapid after that, and the final two spots in the top 10 are truly shocking.
