Planetary scientists have captured an image of near-perfectly circular sand dunes on the surface of Mars. While sand dunes across the Red Planet come in a wealth of shapes and sizes, such well-defined circles are unusual.

You don't often see Earth's dazzling auroras from this angle. NASA astronaut Josh Cassada just snapped a stunning shot of the light display from his perch on the International Space Station (ISS), which flies about 250 miles (400 kilometers) above Earth on average.

NASA's InSight lander detected an unusual quake on Mars. Then the Mars Reconnaissance Orbiter spotted a fresh impact crater.

When it comes to dramatic and awe-inspiring pictures of space, few can contend with what appears to be a pic of, well, nothing at all: a fascinating image of what seems to be a hole in the fabric of space, taken by the NASA/ESA Hubble Space Telescope.

William Shatner has made headlines this week with the announcement that his trip into space wasn't the celebration or high note he thought it would be – instead, it felt like a "funeral for planet Earth".

NASA suspects spaghetti-like debris captured by Perseverance's cameras in July is shredded Dacron netting from gear that landed the rover on Mars.

NASA’s car-sized Perseverance (Percy) Mars rover has been had at work carrying out its science campaign in Jezero Crater on the Red Planet, but it’s equally been busy scouting for sites for NASA’s planned Mars Sample Return (MSR) mission, which is a joint mission with the European Space Agency.

NASA's Curiosity rover recently got up close and personal with a tiny, flower-like mineral deposit on the surface of Mars. The beautiful branching rock, which is just 0.4 inch (1 centimeter) wide, looks a bit like a coral or a sponge. Despite its likeness to a living organism, however, the deposit is not alive and is a fairly common sight across the Martian landscape.

Given the intense temperatures and pressures of Venus, it is indeed impressive that Russian engineers were able to successfully land vehicles there 10 times during the 1970s and 1980s. These were Venera 7 to 14, and Vega 1 and 2 which deployed landers and balloon-born instrument packages.

Multiple images from the Mars Color Imager (MARCI) aboard NASA’s Mars Reconnaissance Orbiter (MRO) were used to generate this view of a regional dust storm obscuring Syrtis Major and Jezero Crater (white circle). The images were acquired on Jan. 9, 2022.

A spacecraft orbiting Mars has made the unexpected discovery of water in Mars' Grand Canyon, otherwise known as Valles Marineris.

Yutu-2 snapped a fuzzy view of something interesting on the horizon.

NASA's Perseverance rover continues collecting Martian rocks. The car-sized robot just snagged its fourth Red Planet rock sample, drilling another core from an intriguing stone that it first sampled a little over a week ago. "A rock so nice, I sampled it twice! Just capped and sealed my fifth sample tube, with another piece from this interesting rock. I'm doubling up on samples at some high-priority targets like this one...

NASA's Perseverance rover has socked away another Martian sample to send home to Earth. The car-sized Perseverance rover drilled a core sample on Monday (Nov. 15), filling a titanium tube with Red Planet rock for the third time ever.

The car-sized robot, and NASA's other Mars craft, had to stand down recently because the Red Planet went behind the sun. NASA's Perseverance Mars rover has emerged from its first "solar conjunction" blackout and gotten back to work on the Red Planet. It's even phoned home with its first Mars photos since reawakening.

Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai, has shared a new picture of Mars taken by the Hope Probe. He said on Saturday that data Hope had gleaned showed larger-than-expected amounts of oxygen on the Red Planet.

The lunar rovers of Apollo 15, 16 and 17 parked American automotive culture on the lunar surface, and expanded the scientific range of the missions’ astronaut explorers.

The dusty, rocky Martian surface and a Chinese rover and lander bearing small national flags were seen in photos released Friday that the rover took on the red planet. The four pictures released by the China National Space Administration also show the upper stage of the Zhurong rover and the view from the rover before it rolled off its platform.
