The search for extraterrestrial intelligence (SETI) has long roots in human history. With the advent of modern technologies, scientists were finally able to start scanning the skies for any sign of life. When the search first started back in the 1960s, it focused almost exclusively on trying to detect radio signals. Over the decades, no irrefutable evidence of any artificial radio signals was ever found. Financial support started to drift away from the discipline, and where the money goes so […]

A major component of NASA's Psyche spacecraft has been delivered to the agency's Jet Propulsion Laboratory in Southern California, where the phase known as assembly, test, and launch operations is now underway. Over the next year, the spacecraft will finish assembly and undergo rigorous checkout and testing before it's shipped to Cape Canaveral, Florida, for an August 2022 launch to the main asteroid belt.

Like millions of people around the world, David Shuster and his 7-year-old daughter cheered wildly as the Perseverance rover was lowered by sky crane to the Martian surface on Feb. 18 to start years of exploration. But for him and a subset of the Mars 2020 science team, true gratification will be delayed.

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 on other worlds.

Data from the NASA spacecraft's journey to Jupiter suggests that Mars may be shedding dust into interplanetary space.
