If you find a structure that looks like ancient life, can you be really sure that it is ancient life?

NASA's Cassini spacecraft sniffed out molecular hydrogen spewing from Enceladus' subsurface ocean. The discovery means Saturn's moon has all the basic ingredients needed to support life.

Later this year, China is launching the Change'5 spacecraft to return a sample from the Moon. The mission will pave the way for future ambitions, including crewed trips to the lunar surface.

After wrapping the final science investigations on the slopes of Cape Tribulation, Opportunity climbed up and over the rim of Endeavour Crater in March and embarked on the journey south toward its next science target: Perseverance Valley.

Now in its third year of orbiting a distant dwarf planet, a spacecraft from Earth is as active as ever. Like a master artist, Dawn is working hard to add fine details to its stunning portrait of Ceres.

There's no verdict quite yet on the giant planet's core, and scientists are still gathering clues about the accuracy of our current solar system formation models.

Arabia Terra has always been a bit of a martian enigma. Planetary scientist Joel Davis takes us on a tour of its valley networks and their significance in telling the story of water on Mars.

Opportunity has begun driving down a long southward slope in Endeavour, heading toward Perseverance Valley.

For nearly two years, Opportunity's world has been tilted 10–25 degrees as it drove down to the lower slopes of the wall of Endeavour Crater. Toward the end of last week, Opportunity pulled itself up and over the lip of the crater.

Our latest roundup of Cassini goodies from Saturn includes Pan, a ravioli-shaped moon that orbits inside the planet's ring system.

This week MAVEN had to execute a short rocket burn in order to prevent a future collision with Phobos. Curiosity (and other rovers) may have played a role in those trajectory predictions.

Driving the Mars Exploration Rovers (MER) mission further into its fourteenth year of surface operations, Opportunity continued hiking the slopes of Cape Tribulation in February and finally reached the crest of Endeavour Crater’s western rim.

The Dawn mission is executing an ambitious bonus goal recently devised for its extended mission. Mission Manager and Chief Engineer Marc Rayman brings us his monthly update.

Scientists have found seven, Earth-size planets orbiting a star just 40 light years away. Three lie in the habitable zone and could have water on their surfaces.

Ted Stryk

Amateur image processor Ted Stryk revisited Voyager 1 data of Enceladus and came across a surprise.

Today, NASA announced progress on a spacecraft that would assess whether Jupiter's Moon Europa is habitable, and earlier this month, an agency-sponsored science team released a report on a separate lander mission that would directly search for signs of life.
