Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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.
Human beings only see the Universe now: 13.8 billion years after the Big Bang. What would the earliest life, anywhere, have seen instead?
Machine learning tools are allowing scientists to better understand forms of intelligence that operate on spaces and timescales utterly unlike our own.
Scientists are livid over the OSTP director's official report to the President. Will it lead to a new golden age for US science, or end it?
200 years ago, we hardly knew anything about our Universe on cosmic scales. Today, there's so much that we know. Here's how we arrived.
Early on, the entire Universe was ionized. Without the forbidden two-photon transition, it would have remained that way for far too long.
