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

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.
