Barnard’s star, the closest singlet star system to ours, has long been a target for planet-hunters. We’ve finally confirmed it: they exist!

The expanding Universe, in many ways, is the ultimate out-of-equilibrium system. After enough time passes, will we eventually get there?

The TRAPPIST-1 system is a treasure trove of possibilities and questions. Observations by JWST have just begun.

“Part of what’s happening now in the world is tension between organic animals and an inorganic digital system which is increasingly controlling and shaping the entire world.”

The detection of two celestial interlopers careening through our solar system has scientists eagerly anticipating more.

The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.

Cognitive systems famously posited by psychologist Daniel Kahneman (1934-2024) may hold the key to a more productive and focused work environment.

Get ready for the most peculiar road trip that will help you understand the vastness and emptiness of the solar system — and Sweden.

There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life’s final extinction will occur.

Our thermodynamic arrow of time explains why the entropy of any isolated system always increases. But it can’t explain what we perceive.

The technology could yield “made-to-order resistance genes” to protect crops against pathogens and pests.

According to Harvard career advisor Gorick Ng, this time-saving system can help us reclaim our work-life sanity.

Some microbes can withstand Earth’s most inhospitable corners, hinting that life may be able to survive similarly extreme conditions on other worlds.

From forgotten Hollywood movies to Frank Herbert’s “Dune,” science fiction illustrates some of our deepest fears about technology.

Susannah Fox, former chief technology officer for the HHS, explains how technology has empowered us to help fill in the cracks of the healthcare system.

For better and worse, the Columbian Exchange plugged the Americas into the global system — and there was no going back.

From inside our Solar System, zodiacal light prevents us from seeing true darkness. From billions of miles away, New Horizons finally can.

Artificial general intelligence will not arise in systems that only passively receive data. They need to be able to act back on the world.

In the early stages of our Solar System, there were three life-friendly planets: Venus, Earth, and Mars. Only Earth thrived. Here’s why.

Nearly half of all stars are born in binary systems, with the most massive ones dying the fastest. It’s not pretty for the “second” star.

Lost in a building or underwater? A new muon-based navigation system could be your guide.

How Daniel Kahneman and Amos Tversky cracked open behavioral economics and enlightened all our choices.

Straddling the bounds of science and religion, Newton wondered who set the planets in motion. Astrophysics reveals the answer.

Space weather poses a tremendous threat to all satellites, knocking all computer systems offline. Is that a recipe for Kessler syndrome?

The 5th brightest star in our night sky is young, blue, and apparently devoid of massive planets. New JWST observations deepen the mystery.

Back in 1990, we hadn’t discovered a single planet outside of our Solar System. Here are 10 facts that would’ve surprised every astronomer.

The future belongs to complexity.

The mind-blowing theory that everything is evolving—from minerals to music—explained in 3 minutes by a Carnegie scientist.

Neuroscientist and author Bobby Azarian explores the idea that the Universe is a self-organizing system that evolves and learns.

Why the road to self-driving vehicles is paved with smarter “dumb” cars.
