Raised ridges spidering across the floor of a Martian crater were likely created by runoff from a long-lost glacier that once draped the planet’s southern highlands. Credit: NASA An ancient crater lake in the southern highlands of Mars appears to have been fed by glacial runoff, bolstering the idea that the Red […]

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 […]

Technicians carefully lower the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument into the belly of the Perseverance rover. (Image credit: NASA/JPL-Caltech) Having safely landed on Mars on Feb. 18, NASA’s newest rover, Perseverance, is just beginning its scientific exploration of the Red Planet. But sometime in the next few […]

Powerful explosive strombolian eruption from two vents on Pico do Fogo volcano.   ANIMATION What would a volcano — and its lava flows — look like on a planetary body made primarily of metal? A pilot study from North Carolina State University offers insights into ferrovolcanism that could help scientists interpret landscape features […]

Vega is the fifth brightest star, excluding the sun, that can be seen from Earth. Credit: Stephen Rahn Astronomers have discovered new hints of a giant, scorching-hot planet orbiting Vega, one of the brightest stars in the night sky. The research, published this month in The Astronomical Journal, was led by University […]

An international research team with members from ETH has developed a new method for directly imaging smaller planets in the habitable zone of a neighboring star system. This opens up new possibilities in the search for extraterrestrial life. In the search for planets capable of sustaining life, an international research […]

“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth,” says Professor Anders Johansen.

Artist’s impression of the protoplanetary disk with magnetic field lines. Credit: Jean Favre CSCS In the last 25 years, scientists have discovered over 4000 planets beyond the borders of our solar system. From relatively small rock and water worlds to blisteringly hot gas giants, the planets display a remarkable variety. […]

An SwRI scientist used a new model to estimate Mars’ bombardment history. This new model indicated that some of the most prominent terrains associated with ancient water activity may be hundreds of millions of years older than previously thought, important data as NASA’s Perseverance rover prepares to land in one […]
