Tantalizing dark streaks on Mars are bone-dry

Anew study said the streaks aren’t caused by water. Instead, the study suggests, the streaks are due to wind and dust.

Venus is more like Earth than we thought.

Data from NASA's Magellan mission suggests Venus could be more geologically active than previously thought. The data shows compelling evidence for ongoing tectonic activity shaping Venus's surface features.

Webb Observes Dynamic Infrared Aurorae on Jupiter

Now, the unique capabilities of the NASA/ESA/CSA James Webb Space Telescope are providing new insights into the Jovian aurorae.

New Signals Hint at a Lost Ocean of Water Concealed Within Mars

Evidence is mounting that a secret lies beneath the dusty red plains of Mars, one that could redefine our view of the Red Planet: a vast reservoir of liquid water, locked deep in the crust.

Early Mars Had Climate Warm Enough to Support Rain

The distribution of valley heads on Mars matches predictions for a climate that includes precipitation rather than just runoff from melting ice caps.

Curiosity Finds First In Situ Evidence of Carbon Cycle on Ancient Mars

A surprise discovery in Gale Crater is the component that was missing in the puzzle of Mars's climate history.

Jupiter storms are made of 'slushee-like' hailstones and lightning

Slushy hail, made of water and ammonia, may form during lightning-packed storms, giving researchers fresh clues about what lurks beneath the planet’s colorful cloud tops.

Hubble Sheds New Light on Atmospheric Composition and Dynamics of Uranus

A 20-year Hubble study of Uranus provide valuable data for understanding the atmospheric dynamics of this distant ice giant, which can serve as a proxy for studying exoplanets of similar size and composition.

Massive collision created Mercury, new theory suggests

A grazing giant collision between two similar-sized rocky bodies likely created Mercury a few billion years ago.

Venus May Be Even More Geologically Active Near Its Surface

An unexpected phenomenon called convection could help explain many of the volcanoes and other features of the Venusian landscape.

Extremely Weird Rock Found on Mars Looks Like Nothing Else Around It

Once again, Mars has presented us with an example of something it seems to have in abundance: extremely peculiar and baffling rocks.
