We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent and based on the same physics…

Curiosity has been exploring a region filled with boxwork formations, which formed billions of years ago when water leaked through rock cracks.

A lucky alignment of galaxies allowed researchers to identify the most powerful and distant "space laser" ever found.

For the first time, researchers have observed and measured weak electrical discharges, known as coronae, on trees during thunderstorms. A new study describes the near-invisible sparkles appearing similarly on branches of several tree species up and down the U…

Researchers find that the amygdala is a sophisticated mediator that chooses between action-based and stimulus-based learning strategies under uncertainty.

New research sheds light on what drives reddish water to emerge from underground to pour onto the Taylor Glacier.

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National Observatory of Athens, published in Nature Astronomy today, a…

A SpaceX Falcon 9 upper stage belched a massive cloud of lithium and other pollutants roughly 62 miles over Europe upon reentry.

Deep in the distant Kuiper Belt, a mysterious object with a snowman-like shape has caught the attention of astronomers.

A discovery by UCLA organic chemists may one day put catalytic converter thieves out of business. In new research, they've used abundant, inexpensive phosphorus as a catalyst in chemical reactions that usually require precious metals like platinum, one of the…

For a starfish, most of life is literally a blur.

Mirrorless is being left on terra firma.

A scientist has claimed the place we cannot see beyond the observable universe is where heaven could be located. This place begins from where the Cosmic Horizon ends. However, critics have dismissed his theory.

Scientists uncover the oldest fossilized butthole, revealing groundbreaking insights into early reptile evolution.

Gravitational lenses could allow us to find black hole binaries long before we're able to measure their gravitational waves.

Conventional electronics process information leveraging the electrical charge of electrons. Over the past few decades, some electronics engineers have been exploring the potential of a different type of device that instead processes and stores data exploiting…

The March 2026 total lunar eclipse will bring a dramatic blood moon to skies across North America, Australia, New Zealand and eastern Asia — if you know where to look.

The night sky is full of wonder. Here's what to look out for tonight.

Life’s genetic blueprint isn’t born in chaos—it’s built in 3D with precision from the very first moments.

Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer near oxygen-…

A 2021 satellite photo shows off the recently uncovered Yilan crater in China, which is most likely the youngest impact structure on Earth. The incomplete ring is also the largest of its kind and only the second impact crater ever found in the country.

By harnessing two natural timescales in resonator arrays, researchers created photonic chips that reliably produce multiple harmonics without active compensation. For decades, scientists and engineers have steadily advanced technologies that control and manip…

Paleontologists in Brazil have identified a previously unknown species of somphospondylan sauropod dinosaur with European affinities, hinting at ancient migration routes that once linked two continents now separated by the Atlantic Ocean.

6 planets will line up in the night sky on Saturday
