Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.

The Orion Nebula surrounded by stars, with a bright green meteor streaking diagonally across the image, evokes the wonder of shooting stars illuminating the night sky.
The Orionids meteor shower peaks October 20th/21st here in 2025, coinciding with a new Moon. See the brightest shooting stars of the year!
A view of deep space showing numerous galaxies of various shapes and sizes scattered across a dark background.
To learn how our Universe grew up, we have to look at large numbers of galaxies at all distances to find out. Good thing we have JWST!
A colorful, irregular galaxy with bright clusters of stars, some possibly from a generation stars before sun, and nebulae against a dark background scattered with distant stars.
Our Sun only arose after 9.2 billion years of cosmic history: with many stars living and dying first. How many prior generations were there?
Collage with hands shaping dough, overlapping U.S. flags, circular architectural elements, and "THE NIGHTCRAWLER" at the top—reflecting on the AI divide woven into the fabric of American life.
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
Since the time of Galileo, Saturn's rings have remained an unexplained mystery. A new idea may have finally solved the longstanding puzzle.
A person holds an oval mirror in front of their face against a blue background, with their reflection appearing abstract and distorted, evoking the surreal influence of ai on self-perception.
If AI is modeled only on human intelligence, will it inherit only human ways of seeing the world?
Two illustrations: on the left, a ball bounces back after hitting a wall; on the right, inspired by quantum advances, the ball passes through—echoing breakthroughs honored with the Nobel Prize in Physics. A child throws the ball in both scenarios.
Quantum mechanics was first discovered on small, microscopic scales. 2025's Nobel Prize brings the quantum and large-scale worlds together.
Book cover titled "Governing Babel" by John P. Wihbey, featuring a stylized blue and black illustration of a tower with small human figures walking—reflecting themes of online speech moderation.
In this excerpt from "Governing Babel," John Wihbey explores how AI is reshaping online moderation by offering tools that can help human moderators, but also raises the risk of disinformation and digital chaos.
Large white letters spelling "AGI" are displayed on a platform in front of steps, with additional bilingual signs reading "REASONERS" and "CHATBOTS" in English and Chinese.
A firsthand look at China’s material progress and clean-tech revolution — and what could happen if we let an authoritarian state steer AI's future.
From the vastness of space, Earth at night reveals its exo-earth beauty, with illuminated continents showcasing a tapestry of lights across North and South America. Major cities and regions emerge from the glowing darkness, painting a vivid picture against the backdrop of oceans.
In 2025, Earth remains the only planet where life is known to exist. Without a second example, "The Stand" has a vital lesson to teach us.
Green circuit board lines form three dollar signs on a dark background with faint circuitry patterns.
Behind the plateau in corporate AI lies a surge in personal and agentic use.
A split image shows a star field on the left and a COSMOS-Web survey area diagram on the right, with labeled NIRCam and MIRI footprints alongside the moon for scale, highlighting galaxies explored by JWST science.
By deeply imaging a large volume of space, COSMOS-Web provides JWST's widest cosmic views. Its gravitational lenses reveal a big surprise.
As the Universe ages, it continues to gravitate, form stars, and expand. And yet, all this will someday end. Do we finally understand how?
Collage featuring a man operating early computer equipment and a man in aviator goggles, with the text "THE NIGHTCRAWLER" above them—capturing the creative sparks of innovation and adventure.

"Could black holes be the key to a quantum theory of gravity, a deeper theory of how reality, of how space and time works? Well, I think so."
From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?
An astronaut stands proudly on the moon's surface near scientific equipment and a lunar lander, as the American flag waves in the background, symbolizing a pioneering USA nation.
As October begins, thousands of longtime NASA employees are leaving the agency. 4000+ will exit by January 9, 2026, changing NASA forever.
Book cover with the title "The Formula for Better Health: How to Save Millions of Lives—Including Your Own" by Tom Frieden, MD, MPH, featuring illustrated silhouettes of people and a nod to Alice Hamilton’s pioneering work in public health.
In this excerpt from "The Formula for Better Health," Tom Frieden explores how Alice Hamilton transformed public health in her fight against lead poisoning.
