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

A split image showing a human hand making an "OK" gesture on the left, and an alien hand pointing with a glowing fingertip on the right.
The unanswered questions about sex, love, and pregnancy in space could shape the future of humanity more than we think.
Visualization of the timeline of the universe, from the beginning big bang to the present.
The Universe is expanding, the expansion is accelerating, and some galaxies even recede faster-than-light. Can we see a change in real time?

Even the most brilliant mind in history couldn't have achieved all he did without significant help from the minds of others.
A luminous dying sun with jets and swirling clouds appears at the center of a dark background, encircled by concentric patterns—an image reminiscent of Hubble’s stunning cosmic view.
Before Sun-like stars die, they transition from AGB red giants into preplanetary nebulae. Here's how Hubble sees the famous Egg Nebula.

Carl Sagan's baloney detection kit taught us how to separate good science from the work of charlatans. In 2026, that matters more than ever.
A laptop made of a rough, brown, stone-like material with green squiggly lines emerging from its screen, set against a black background.
AI is not a rupture in history, but a continuation of intelligence emerging where information becomes systematically arranged.
Silhouette of NASA's Europa Clipper spacecraft with antennas poised against a colorful planetary surface, sparking dreams of alien life.
No claim has even made it halfway up the Confidence of Life Detection (CoLD) scale, but 21st century science is just beginning to unfold.
Side-by-side comparison of the Pillars of Creation in space, showing Hubble's visible light image and JWST's infrared image. Labels indicate "Hubble (Visible)" and "JWST (Infrared)".
Here in our modern Universe, it's cosmic dust that forms planets, complex molecules, and enables life. But how did the Universe create it?
A book cover with colorful shapes set against a mysterious Dark Forest backdrop.
Writer and media theorist Bogna Konior connects cosmos and computer by reconsidering our eerily silent Universe.
star vs planet vs brown dwarf
13.8 billion years have passed since the Big Bang, but many stars will survive for longer than that. What's the longest-lived a star can be?
An older person sits on a chair against a white backdrop, with a colorful outer space scene digitally added around the background.

Astronomer Jill Tarter explains why SETI is really about technology, patience, and learning how to tell alien signals from our own.
Two bright celestial objects, including the brightest planet, shine in the night sky, partially obscured by clouds and surrounded by smaller, faint stars.
Even at its faintest, Venus always outshines every other star and planet that's visible from Earth, and then some!
A dense field of distant galaxies and bright stars against a black background, as captured in a JWST early galaxies deep space telescope image.
Many collaborations have used JWST to take deep-field images: some wider and some deeper than others. Here's how it can surpass them all.

A century ago, quantum physics overthrew our view of a deterministic Universe. A profound 21st century theorem closes the door even further.
Book cover titled "Governing Pandora" by Andrea Bonime-Blanc featuring a colorful, geometric open box on a black background with white text—reflecting themes relevant to the Age of Pandora.
Why we should balance innovation with stewardship — while reframing the “techno-optimists versus doomers” polarization.

30 years ago, we didn’t know other stars had planets orbiting them. Now, we may be on the verge of finding Earth’s Twin. Sara Seager explains.
cosmic rays
At the upper limits of what's energetically possible, cosmic rays still persist. What happens if a human gets hit by the most energetic one?
A man with glasses and a beard works on a clay sculpture using a tool, set against a collage of historical art images and decorative patterns inspired by traditional Pasto varnish techniques.
The revival of Pasto Varnish shows how living heritage can survive if knowledge is passed on in time.

Many top performers start behind — and overtake the early leaders later.

Our great hope is that today's indirect, astrophysical evidence will someday lead to successful direct detection. What if that's impossible?
