Webb Detects Complex Structures in Upper Atmosphere of Saturn

Astronomers using the NASA/ESA James Webb Space Telescope have detected a series of dark, bead-like and asymmetric star-shaped features in the ionosphere and stratosphere of Saturn.

NASA Says Mars Rover Discovered Potential Biosignature

A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. 

Scientists uncover hidden shards of Mars’ violent birth, frozen for billions of years

Mars isn’t the neatly layered world we once imagined — its mantle is filled with ancient, jagged fragments left over from colossal impacts billions of years ago. 

New Moon Discovered Orbiting Uranus

Using NASA’s James Webb Space Telescope, a team has identified a previously unknown moon orbiting Uranus, expanding the planet’s known satellite family to 29. 

Astronomers Find Hidden Volcano on Mars

The researchers posit that the volcano could have supported conditions favorable for life in the once-watery Jezero crater.

NASA Mars Orbiter Captures Volcano Peeking Above Morning Cloud Tops

A new panorama from NASA’s 2001 Mars Odyssey orbiter shows one of the Red Planet’s biggest volcanoes, Arsia Mons, poking through a canopy of clouds just before dawn.

A 'Crazy Idea' About Pluto Was Just Confirmed in a Scientific First

When the New Horizons spacecraft swept past Pluto and Charon in 2015, it revealed two amazingly complex worlds and an active atmosphere on Pluto.

We now have a good idea about the makeup of Uranus' atmosphere

20 years of observations have given us more knowledge about the icy giant.

Uncovering Ongoing Surface Modification On Europa

The JWST shows that ice on Europa is developing at different rates in different places, such as Tara Regio, where crystalline ice (lighter colors) is found on the surface as well as below the surface.

NASA's MAVEN Makes First Observation of Atmospheric Sputtering at Mars

After a decade of searching, NASA's MAVEN (Mars Atmosphere Volatile Evolution) mission has, for the first time, reported a direct observation of an elusive atmospheric escape process called sputtering.

Scientists' hunt for 'Planet Nine' finds evidence of dwarf world

A US-trio appears to have discovered a distant dwarf planet with a 25,000-year orbit bringing it into the ring of icy rocks around the solar system - the Oort cloud.

Venus Harbors Secret Asteroids That Could Threaten Earth

Dangerous rocks may co-orbit with Venus, but new research suggests only a space-based mission can prove it.

Scientists Find Jupiter Used to Be Twice Its Current Size

New research suggests that Jupiter used to be at least twice as big as it is today . Over time, the bloated world cooled off, contracting to the relatively humbler size it is today.

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.
