NASA astronaut Chris Williams talks about his journey from the Montgomery County school system to space.

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed an elliptical galaxy known as NGC 4486B. Results of the observational campaign, published Dec. 16 on the arXiv preprint server, deliver important insights into the …

Ever wondered why our seasons feel the way they do, despite the Earth being closest to the Sun during winter?

A dormant volcano in Ethiopia erupted after 10,000 years of silence. This event shows how the world's little-known volcanoes pose the greatest threat.

An 11-year-old’s beachside discovery has stunned scientists and triggered a major rewrite of prehistoric history. Buried beneath Britain’s crumbling cliffs lies evidence of a marine predator so massive, it rivals the blue whale, and it’s unlike anything seen …

Scientists have reversed electromagnetic waves in time—not science fiction, but a real experiment that challenges what we know about physics.

By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird part-solid, part-liquid-like state thought to exist inside Earth's inner core is indeed possible.

A teenager agreed to babysit a neighbor’s kids for a few hours, expecting a simple job and some extra cash. Instead, chaos ensued when the energetic eight-year-old destroyed his Nintendo Switch, turning a routine favor into a stressful ordeal. When he pol…

Our beginner-friendly guide helps you get familiar with the moon, Jupiter, nebulas and galaxies this Christmas.

Scientists in Paris discovered two new substances with incredible radioactivity. It earned them the Nobel Prize in Physics but would ultimately kill one of them.

Giant amphipod species Alicella gigantea, once thought to be very rare, is found to inhabit the majority of Earth's deep ocean floors.

A 50-year-old scientific mystery surrounding tissue regeneration after severe damage has finally been solved, offering exciting new insights into cell survival and repair.

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova—the explosive death of a massive star—at an unprecedented cosmic distance.

An astronaut on the ISS photographed a "lunar halo" over the Indian Ocean, revealing ice and rare optical phenomena from space.

Recent images of the interstellar object 3I/ATLAS show a tightly collimated anti-tail jet that extends out to at least 400,000 kilometers…

For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms.

How well do you know that organ between your ears? Test your recognition of neuroscience terms with this word search.

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Graphene is often described as a wonder material. It is strong, electrically conductive, thermally efficient, and remarkably versatile. Yet despite more than a decade of excitement, many graphene-based technologies still struggle to move beyond the laboratory.

A new type of lidar is allowing physicists to study cloud tops at a resolution 100 to 1,000 times higher than before.

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that appears to be slowly rotating as a whole. This coordinated mot…

Just in time for Christmas, a vast star-forming region shaped like a Christmas tree is lighting up space 2,700 light-years from Earth. NGC 2264 is a vast region of space where new stars are actively forming, located about 2,700 light-years from Earth in the f…

Perseverance has just uncovered something that doesn’t belong to Mars, and possibly not even the solar system.

They won't be home for Christmas, but that's okay.
