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

Known as hypervelocity stars, we originally thought just one would be ejected every 100,000 years. The real number is much greater.
A vibrant solar flare erupts from the Sun's surface, showcasing sun activity in 2024 and emitting bright ultraviolet light in this detailed astrophotograph.
Northern lights in the American South, clusters of huge geomagnetic storms—the Sun is throwing a tantrum right on schedule.

Waistlines are expanding in most countries, except for a skinny list of nations bucking the trend.
A computer-generated image of a bright celestial object with an accretion disk, possibly representing what the sun looked like when it was born.
Newborn stars are surrounded only by a featureless disk. Debris disks persist for hundreds of millions of years. So when do planets form?

From forming bound states to normal scattering, many possibilities abound for matter-antimatter interactions. So why do they annihilate?
A female physician wearing a lab coat and glasses examines medical images on a lightboard. The background consists of a green and purple abstract design.
Female physicians tend to practice medicine as it should be practiced: with care and compassion.
SARS-CoV-2 first emerged in humans in 2019. Despite much noise generated by lab leak proponents, the evidence indicates a natural origin.
A composite image shows the sun's path in the sky at different times of the year over a grassy landscape, with three arches of sun positions represented by dots, illustrating the earliest solstice.
On June 20, 2024, the summer solstice occurs at its earliest moment since 1796: when George Washington was President of the USA. Here's why.

There are two different ways to measure the expansion rate of the Universe, and they don't agree. And no, new measurements don't help.
Two people are tandem skydiving, falling through the air above a landscape of fields, mountains, and coastline under a clear sky.
Is gravity weaker over distances of billions of light-years?
A new all-time record! JWST's discovery of JADES-GS-z14-0 pushes the earliest galaxy ever seen to just 290 million years after the Big Bang.
