Space weather experts warn that a "moderate" geomagnetic storm could rock Earth over the weekend, potentially lighting the skies with vibrant auroras across large parts of the U.S. and Europe.

Breathing patterns among humans are so unique that they can work as an identification tool, scientists report. They propose someday using breath as a way to diagnose disease.

The Colorado River basin has lost a Lake Mead’s worth of water in the last 20 years — and scientists say we’re passing a "critical point" where pumping groundwater will become too expensive.

The Daniel K. Inouye Solar Telescope captured the sharpest-ever images of the sun’s surface, revealing ultra-fine bright and dark stripes called striations that are caused by powerful magnetic fluctuations.

The Zanj, enslaved people largely from Africa, rebelled at the same time they were ordered to build a massive system of canals in what is now Iraq, a new study finds.

In patients showing cognitive decline, a new blood test for Alzheimer's is expected to make diagnosis more convenient, accessible and inexpensive than other existing tests.

NASA's Chandra X-ray Observatory has captured a striking image of a distant quasar from the "cosmic noon," including a giant energy jet "being illuminated by the leftover glow from the Big Bang itself."

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

Researchers have found that ocean acidification entered a "danger zone" in 2020, suggesting increased carbon dioxide levels have caused Earth to breach another planetary boundary.

For the first time, scientists have imaged the elusive south pole of the sun. The images captured by the Solar Orbiter spacecraft reveal our star's magnetic field is a powder keg ready to blow.

Astronomers have discovered a new class of bright, long-lasting cosmic explosions that offer a new probe into studying the universe's most distant black holes.

Scientists are developing a new device that fits inside a menstrual pad and checks for "biomarkers" of disease in period blood.
