Two versions of a Curiosity selfie: narrow and wide

NASA's Curiosity Mars rover took this 360-degree selfie using the Mars Hand Lens Imager, or MAHLI, at the end of its robotic arm. The selfie comprises 81 individual images taken on Nov. 20, 2021—the 3,303rd Martian day, ...

A one-way phone call from Mars

This November, ESA's Mars Express spacecraft carried out a series of experimental communication tests with the Chinese (CNSA) Zhurong Mars rover. Mars Express successfully caught data sent up 'in the blind' by the rover and ...

Lunar radar data uncovers new clues about moon's ancient past

The dusty surface of the moon—immortalized in images of Apollo astronauts' lunar footprints—formed as the result of asteroid impacts and the harsh environment of space breaking down rock over millions of years. An ancient ...

Mysterious clouds could offer new clues on dark matter

The hunt for gravitational waves, ripples in space and time caused by major cosmic cataclysms, could help solve one of the Universe's other burning mysteries—boson clouds and whether they are a leading contender for dark ...

Arecibo data still yielding galactic insights

Data collected by the Arecibo Radio Telescope before it collapsed late last year will help astronomers better understand how our local neighborhood of galaxies formed.
