The sample of material delivered to our planet from the near-Earth asteroid Ryugu contained a mixture of extraterrestrial (helium and neon) and terrestrial...
Astronomers using the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory have discovered two...
This new image from the High Resolution Stereo Camera (HRSC) aboard ESA’s Mars Express orbiter shows a diverse region southeast of the Pickering crater...
On December 24, 2021, NASA’s InSight lander recorded a magnitude 4 marsquake with a distinct signature rippling across the surface of Mars. In a pair...
A major question in Mars history is whether the planet had an ocean in its northern hemisphere. New research provides evidence for a northern ocean or...
Radiation resistance of microbes is a key parameter in considering survivability of microbes over geologic times on the frigid, arid surface of Mars that...
A new image from the NASA/ESA Hubble Space Telescope shows two tails of dust ejected from the 160-m-wide asteroid moonlet Dimorphos, which orbits a larger,...
3200 Phaethon, one of the largest potentially hazardous asteroids, rotates once every 3.6 hours, and that rotation period is decreasing by about 4 milliseconds...
The dwarf planet Haumea resides in the Kuiper Belt beyond the orbit of the outermost planet Neptune.

New videos captured by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express orbiter show the rare moment of the Martian moon Deimos passing...
In the search for life beyond Earth, subsurface bodies of water in the outer Solar System are some of the most important targets. That’s why NASA and...
On September 26, 2022, NASA’s Double Asteroid Redirection Test (DART) intentionally slammed into Dimorphos, a moonlet of the asteroid Didymos. According...
Both the first and second interstellar meteors, IM1 and IM2, are outliers in material strength and may have originated in supernova explosions, according...
The subsurface of Mars during the Noachian period was likely to have been habitable for microorganisms that feed on hydrogen and produce methane, according...
