NASA’s InSight lander has recorded the largest Marsquake yet
Any Martians out there should learn to duck and cover. On May 4, the Red Planet was rocked by a roughly magnitude 5 temblor, the largest Marsquake detected to date,…
Lava and frost may form the mysterious lumps on Jupiter’s moon Io
On Jupiter’s moon Io, lava creeping beneath frost may give rise to fields of towering dunes. That finding, described April 19 in Nature Communications, suggests that dunes may be more…
U.S. planetary scientists want to explore Uranus and Enceladus next
The continuing search for life beyond Earth is driving many of the priorities for what’s next when it comes to U.S. planetary exploration. In a new report that could shape…
Europa may have much more shallow liquid water than scientists thought
Europa’s frozen surface is covered with distinctive pairs of ridges that straddle troughs of ice. These double ridges are the most common features on the Jovian moon. But scientists don’t…
Here’s how NASA’s Ingenuity helicopter has spent 1 year on Mars
One year ago, Ingenuity took its first flight on Mars. And its story since is that of a real-world little helicopter that could. Ingenuity traveled to the Red Planet attached…
This is the biggest known comet in our solar system
The nucleus of a comet discovered in 2014 is the largest ever spotted. The “dirty snowball” at the center of comet C/2014 UN271 is about 120 kilometers across, researchers report…
New thermal maps of Neptune reveal surprising temperature swings
Neptune’s atmospheric temperature is on an unexpected roller-coaster ride, and it could take decades for scientists to piece together what’s happening at the distant planet. The ice giant’s global temperature…
Mars has two speeds of sound
On Mars, the speed of sound depends on its pitch. All sound travels slower through Mars’ air compared with Earth’s. But the higher-pitched clacks of a laser zapping rocks travels…
Diamonds may stud Mercury’s crust
A treasure trove of diamonds may be sown into Mercury’s cratered crust. Billions of years of meteorite impacts may have flash-baked much of Mercury’s surface into the glittery gemstones, planetary…
