At the fringes of the Greenland Ice Sheet, where glaciers are constantly melting, water rushes everywhere through an intricate system of lakes and streams that branch out like slip and slide shoots of super chilled, bright turquoise water. Some of that water eventually cascades straight into the surrounding land and […]

The permanent rise of oxygen in the Earth’s atmosphere, which fundamentally changed the subsequent nature of Earth’s habitability, occurred much later than thought, according to new research. And the study, from an international team led by the University of Leeds and including researchers from the University of California-Riverside, Harvard University, […]

The Perseverance rover used its SuperCam laser to study this strange green rock on Mars. (Image credit: NASA/JPL-Caltech) Perseverance’s laser hasn’t yet penetrated the mystery of a strange Martian rock near the rover’s new digs. NASA’s rover is waiting for its companion, the Ingenuity helicopter, to make the first-ever powered flight on […]

ANIMATION Jovian jet streams above the cloud tops measured using the aftermath of comet collision. Working with a team led by French astronomers, Southwest Research Institute scientists helped identify incredibly powerful winds in Jupiter’s middle atmosphere for the first time. The team measured molecules exhumed by the 1994 impact of comet […]

ANIMATION Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, a team of astronomers have directly measured winds in Jupiter’s middle atmosphere for the first time. By analyzing the aftermath of a comet collision from the 1990s, the researchers have revealed incredibly powerful […]

A visualization of the Glashow event recorded by the IceCube detector. Each colored circle shows an IceCube sensor that was triggered by the event; red circles indicate sensors triggered earlier in time, and green-blue circles indicate sensors triggered later. This event was nicknamed “Hydrangea.” Credit: IceCube Collaboration The South Pole […]

Nearly 42,000 years ago, when Earth’s magnetic fields reversed, this triggered major environmental changes, extinction events, and long-term changes in human behavior, a new study reports. The findings, made possible by a new radiocarbon record derived from New Zealand’s ancient kauri trees, raise important questions about the evolutionary impacts of […]
