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

Circular astronomical image showing constellations and celestial objects labeled against a dark sky, reminiscent of a NASA PUNCH video sun corona visualization, with a timestamp of 2025-06-03 01:52 at the bottom left.
Launched in March, the PUNCH mission has viewed two incredible coronal mass ejections, tracking them farther from the Sun than ever before.
A flowchart with a large question mark at the top leads to boxes containing photos, abstract patterns, and arrows connecting each step on a textured green background.
Annie Duke, a poker champion turned decision scientist, talks with Big Think about how to choose well under uncertainty.
The tiniest galaxies of all are the most severely dominated by dark matter. Could black holes be the cause of the extra gravity instead?
A digital illustration showing a glowing blue particle on the left, evoking cosmic inflation, transitioning into a geometric, grid-like structure on a purple background on the right.
A few physical quantities, in all laboratory experiments, are always conserved: including energy. But for the entire Universe? Not so much.
A woman, resembling a paranormal investigator, holds a rectangular glass dish above her eyes, which are illuminated by light shining through the dish in a dark setting.
For his new book, “The Ghost Lab,” Matt Hongoltz-Hetling spent time with paranormal investigators to understand their relationship with science and society.
Timeline of the universe from the Big Bang, as described in cosmology, showing inflation, formation of atoms, stars, galaxies, and expansion to the present day over 13.8 billion years.
If you want to understand the Universe, cosmologically, you just can't do it without the Friedmann equation. With it, the cosmos is yours.
A large yellow hot air balloon with a smiley face is shown on the left; on the right, a bunch of parfit smiley face balloons float against a cloudy sky.
If happiness is an absolute good, would 1 billion slightly happy people be better than 1 million incredibly happy people?
A blue planet with visible rings and several small, bright Uranus moons is set against a darkened black background.
Viewing Uranus's largest moons with Hubble, astronomers hoped to find darkening on the trailing side. They found the exact opposite instead.
A worker in protective gear operates machinery in an industrial facility, with a partial overlay of solar panels and geometric patterns above—hinting at the innovative spirit found in stellar societies.
The cofounders of think tank RethinkX are convinced that humanity is undergoing civilizational phase change.
A white dinosaur skull silhouette on a black background with red, rough, scribbled lines evokes the intrigue of the dinosaur myth.
In "The Shortest History of the Dinosaurs," Riley Black reveals the bold mammals that thrived in the Age of Reptiles.
An illustration shows a cosmic ray entering Earth’s atmosphere, creating a cascade of secondary particles—some of the highest energy particles astronomers study—detected by an array of sensors on the ground.
On Earth, our particle accelerators can reach tera-electron-volt (TeV) energies. Particles from space are thousands of times as energetic.
Image of two large elliptical galaxies surrounded by several smaller, colorful galaxies and stars against a dark background in space.
The first galaxies were irregular blobs of gas and stars. But modern features, like spiral arms and bars, appeared earlier than expected.
A grey, icy planet or moon with surface cracks is shown against a backdrop of stars and the Milky Way galaxy.
The hunt for extraterrestrial life begins with planets like Earth. But our inhabited Earth once looked very different than Earth does today.
An artist's impression of a cluster of stars.
If the Universe is 13.8 billion years old today, but different ages the farther we look back, what does it mean for a star to be the first?
A man in glasses and a suit jacket, resembling John Green, stands in front of a light background with a purple rectangle and abstract black lines.
John Green opens up about his struggle to remain hopeful while writing about suffering and injustice.
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.
The COSMOS-Web has just finalized their release of their full field: larger and deeper than any other JWST program. Here's what's inside.
A large circular particle accelerator laboratory with various machines, cables, and equipment; two people are working near the center on experiments related to the muon g-2 anomaly.
When theory and experiment disagree, it could mean new physics. This time, they solved the muon g-2 puzzle, and saved the Standard Model.
Interior view of a large observatory telescope in operation at night, with orange light trails and a starry sky visible through the open roof.
The Vera C. Rubin Observatory in Chile will image the southern sky using the largest digital camera ever built.
Book cover with a gray textured background, featuring the title "DE KAI RAISING AI" and the subtitle "An essential guide to raising AI and parenting our future," all in white capital letters.
In "Raising AI," De Kai argues that today's AIs are already more like us than we think they are.
Edwin Hubble and Andromeda galaxy
For decades, astronomers have claimed the Milky Way will merge with Andromeda in ~4 billion years. Here's why, in 2025, that seems unlikely.
