Scripps Oceanography researcher’s assertion bolstered by series of new studies. New research lends credence to an unorthodox retelling of the story of early Earth first proposed by a geophysicist at Scripps Institution of Oceanography at UC San Diego. In a study published on March 15, 2021, in the journal Earth and […]

NASA’s Galileo spacecraft caught Jupiter’s moon Io, the planet’s third-largest moon, undergoing a volcanic eruption. Locked in a perpetual tug of war between the imposing gravity of Jupiter and the smaller, consistent pulls of its neighboring moons, Io’s distorted orbit causes it to flex as it swoops around the gas […]

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 […]
